🧲 Premium Reliable Copper Crucible – C10200 E-Beam Use

✨ NiTiCu Metal supplies custom copper crucible solutions for e-beam evaporation systems, vacuum coating equipment, laboratory evaporation sources, and precision machined copper components. This product page focuses on C10200 oxygen-free copper, a high-conductivity copper grade used when customers need clean machining, stable thermal transfer, and drawing-based crucible support. Unlike alumina, graphite, tungsten, or molybdenum containers, a copper crucible is selected mainly for heat transfer, e-beam source compatibility, and custom geometry rather than for ordinary uncooled high-temperature melting.

🌟 A copper crucible is especially useful in evaporation equipment where the crucible or liner works together with the e-gun pocket, cooling structure, and deposition material. The design may look simple from the outside, but the real performance depends on internal cavity shape, rim thickness, bottom radius, fit with the hearth, machining quality, and thermal contact. NiTiCu can manufacture according to customer drawings, samples, or dimensional requirements, including small research pieces and repeated industrial batches.

🔬 What Is a Copper Crucible?

🧪 A copper crucible is a machined copper container, liner, insert, or evaporation source component used to hold material during controlled thermal processing. In many cases, it is not a free-standing refractory crucible used in open flame. Instead, it is part of a vacuum deposition system or water-cooled furnace structure where the surrounding equipment controls temperature, cooling, and energy input. This distinction is important because copper has excellent thermal conductivity but a melting point lower than refractory metals.

🌙 For e-beam evaporation, a copper crucible can be used when the deposition material can be run from the e-gun pocket and a liner is still required. The customer must select the proper cavity size, fill level, ramp recipe, and liner material according to the evaporation material and equipment model. A correctly made copper crucible helps fit the source pocket accurately, supports stable handling, and provides a clean machined copper interface for the process.

📊 Key Copper Material Data

📐 Copper is element Cu, atomic number 29, with a relative atomic mass of 63.546. Its density is about 8.96 g/cm³ and its melting point is about 1084.62°C. These values explain both the advantage and the limitation of a copper crucible. The material conducts heat very well and can be machined accurately, but it should not be described as a universal ultra-high-temperature refractory container.

⚙️ Property	📌 Typical Reference Value	🧭 Practical Meaning
🧪 Element	Copper / Cu	Base material identity
🔢 Atomic Number	29	Confirms elemental copper
⚖️ Relative Atomic Mass	63.546	Useful for technical documentation
🧱 Density	About 8.96 g/cm³	Helps estimate part weight
🌡️ Melting Point	About 1084.62°C	Shows limitation of uncooled use
🔥 Boiling Point	About 2560°C	Useful for material reference
⚡ Conductivity Nature	High thermal and electrical conductivity	Core reason for copper crucible selection
🛠️ Processing	Machining, drilling, turning, milling	Suitable for custom source components

🧭 Because copper is highly conductive, it can quickly transfer heat away from localized hot zones when the design includes proper contact or water cooling. This is why copper parts are widely used in electrical equipment, heat exchangers, vacuum components, and thermal management structures. For a custom copper crucible, the engineering value comes from geometry, material grade, surface quality, and compatibility with the equipment.

💎 Why Choose C10200 Oxygen-Free Copper?

🔷 C10200 is an oxygen-free wrought copper grade. Copper Development Association data lists C10200 as Oxygen-Free OF copper, with minimum Cu content of 99.95% and maximum oxygen content of 0.0010%. It also notes that in the annealed condition, this alloy has a minimum conductivity of 100% IACS. These numbers make C10200 a strong choice for precision copper crucible parts where conductivity and material cleanliness are important.

🧾 Material Grade	📊 Key Data	🎯 Why It Matters
C10200	Oxygen-free copper	Cleaner copper grade for technical parts
Cu Content	Min. 99.95%	Supports high-purity copper supply
Oxygen	Max. 0.0010%	Reduces oxygen-related concerns
Conductivity	Min. 100% IACS in annealed condition	Useful for conductive and thermal designs
Form	Wrought copper	Suitable for machined custom components
Typical Use Direction	Vacuum, electrical, thermal and precision copper parts	Matches e-beam and equipment applications

🛠️ For a copper crucible, C10200 is often preferred over general copper when the customer wants better control of oxygen content and reliable conductivity. The grade can be turned, milled, drilled, bored, chamfered, polished, and inspected according to drawing. If the design includes a special cavity, step, thread, flange, side groove, or cooling feature, C10200 oxygen-free copper gives a practical base for custom manufacturing.

🧩 Copper Crucible vs Refractory Crucible

⚖️ Customers sometimes compare copper, graphite, alumina, molybdenum, and tungsten crucibles as if they perform the same job. They do not. Graphite and alumina are often selected as heat-resistant containers. Molybdenum and tungsten are refractory metals used in vacuum or special high-temperature environments. A copper crucible is different: it is normally chosen for high thermal conductivity, precision fit, and equipment-specific evaporation or cooling design.

🏺 Crucible Type	🔥 Main Strength	⚠️ Key Limitation
Copper Crucible	Thermal conductivity, e-beam source fit, machining accuracy	Not for uncooled ultra-high-temperature use
Graphite Crucible	Thermal shock resistance and high-temperature service	May contaminate some materials
Alumina Crucible	Ceramic stability and oxidation resistance	Brittle and less conductive
Molybdenum Crucible	Refractory metal performance in vacuum	Higher cost and different machining route
Tungsten Crucible	Very high melting point	Expensive and difficult to machine

🪐 This comparison helps buyers avoid selecting the wrong product. If your process requires a container for direct open-air high-temperature melting, a copper crucible may not be suitable. If your process requires a machined liner for e-beam evaporation, a custom insert for a copper hearth, or a water-cooled copper component, copper can be the right material choice.

⚙️ Custom Design Options

🧰 NiTiCu focuses on drawing-based production. A custom copper crucible can be made as a simple cylindrical liner, a stepped insert, a tapered cup, a rectangular pocket, a multi-cavity part, or a water-cooled copper component depending on the application. The customer can provide a drawing, old sample, equipment model, or target dimensions for review.

📦 Custom Item	✅ Available Direction
Shape	Round, tapered, stepped, rectangular, special cavity
Material	C10200 oxygen-free copper, C11000, C12200 or custom copper grade
Diameter	Custom OD and ID according to source pocket
Height	Short liner, deep cup, or drawing-based depth
Bottom	Flat, rounded, thick bottom, stepped bottom
Rim	Straight rim, chamfered rim, thick rim, flange
Holes / Grooves	Thread, side hole, locating groove, water channel if required
Surface	Machined, polished, deburred, cleaned
Inspection	Size check, visual check, material certificate support

🔩 For e-beam evaporation use, the cavity shape is very important. A small difference in bottom radius or wall angle may affect how material sits inside the crucible, how the beam interacts with the charge, and how the part fits into the equipment. Before production, NiTiCu recommends confirming the critical dimensions, especially OD, cavity diameter, cavity depth, bottom thickness, and rim height.

🌡️ E-Beam Evaporation Use

🛰️ In an e-beam evaporation system, the material is heated by an electron beam under vacuum. The source assembly, hearth pocket, crucible liner, charge material, power recipe, and deposition rate must work together. A copper crucible can be useful when the equipment design requires a copper liner or machined insert with good thermal conduction and accurate fit.

🔭 Kurt J. Lesker notes that copper crucibles are available for e-beam sources and that custom sizes are available upon request. It also explains that copper crucibles can be good options for materials run directly from the e-gun pocket when a liner is still required. This matches the positioning of NiTiCu’s product: not a generic melting cup, but a custom copper crucible for technical evaporation systems.

🧪 E-Beam Requirement	🧩 Copper Crucible Design Focus
Source pocket fit	Accurate OD, height and bottom form
Material loading	Correct cavity depth and fill volume
Thermal transfer	Good contact surface and copper conductivity
Clean operation	Smooth internal machining and deburring
Repeat process	Consistent dimensions for repeat orders
Special system	Drawing-based custom size support

🌌 Customers should also pay attention to fill level and process recipe. Overfilling, wrong ramp settings, strong power fluctuation, and improper cooling can damage a crucible or cause unstable deposition. The part supplier can control material, dimensions, machining, and packing, but the process engineer must control operating conditions.

💧 Water-Cooled Copper Crucible Direction

🚿 Some customers use the term copper crucible for water-cooled copper hearths, cold crucible systems, or furnace copper containers. In this direction, the copper body is normally designed to transfer heat rapidly into cooling water. The part may include internal water channels, external jackets, pipe connections, brazed or welded structures, sealing surfaces, and mounting holes.

🧊 A water-cooled copper crucible must be reviewed more carefully than a simple e-beam liner. The drawing should define water inlet and outlet, flow direction, wall thickness around channels, sealing method, pressure requirement, leak test expectation, and connection type. If a customer only sends an outside dimension without cooling details, NiTiCu will need more information before quoting.

💦 Cooling Design Item	📌 Information Needed
Water Channel	Diameter, path, depth and wall allowance
Inlet / Outlet	Thread, tube, flange or custom connector
Pressure	Working pressure and test pressure
Flow Rate	Required or estimated cooling flow
Sealing	O-ring, brazing, welding or mechanical seal
Mounting	Hole positions, slots and reference surfaces
Inspection	Leak test, dimensional check and photos

🛡️ For cooled designs, safety margin matters. Thin walls around water channels can increase machining risk, while overly thick walls may reduce cooling response. A well-designed copper crucible should balance mechanical strength, cooling efficiency, manufacturability, and maintenance access.

🏭 Application Areas

🏗️ A custom copper crucible can serve many industrial and laboratory systems. Typical uses include e-beam evaporation sources, vacuum coating equipment, research deposition systems, water-cooled furnace hearths, cold crucible concepts, thermal test fixtures, custom copper liners, and equipment spare parts. The best design depends on the customer’s machine and process.

🏭 Application	🔍 How Copper Helps	📋 Common Buyer Request
E-Beam Evaporation	Accurate liner fit and good thermal conduction	Cavity liner by drawing
Vacuum Coating	Clean machined copper component	Small batch custom insert
Laboratory Equipment	Custom research source part	One piece or trial quantity
Water-Cooled Furnace	Fast heat extraction	Copper body with cooling channels
Copper Hearth	Stable conductive base	Machined pocket or hearth plate
Custom Equipment	Drawing-based copper component	OEM-style part support

🔬 In laboratory projects, customers may need only one or two pieces to test the design. In industrial equipment, they may need repeated batches with the same dimensions and surface finish. NiTiCu can support both directions, but the inquiry should clearly state whether the copper crucible is a prototype, spare part, replacement component, or production item.

📐 Machining and Tolerance

🪚 Copper is ductile and conductive, but it is not always easy to machine perfectly. Tool geometry, clamping method, cutting speed, burr control, and polishing method can influence the final appearance. A custom copper crucible may require internal boring, pocket milling, edge chamfering, drilling, threading, and surface cleaning. Tight tolerances are possible for many features, but they should be defined realistically.

🧿 For precision work, customers should mark critical dimensions on the drawing. Not every surface needs the same tolerance. The OD may control fit with the source pocket, while the inner cavity may control loading volume. The rim may require smooth handling, while bottom thickness may influence heat transfer. Clear priorities help control both cost and lead time.

📦 Packaging and Shipment

🚚 Copper surfaces can be scratched or oxidized during handling if they are not protected. NiTiCu can pack each copper crucible individually with soft wrapping, sealed bags, foam inserts, reinforced cartons, or wooden cases for larger parts. Before shipment, we can provide product photos so customers can check visible shape, surface, and packing arrangement.

🏷️ For international shipment, normal documents may include invoice, packing list, product label, material certificate when required, and dimensional inspection notes for drawing-based parts. If the order is urgent for equipment repair or laboratory testing, please tell us the delivery deadline early so we can discuss production and courier options.

📑 Quality Documentation

📋 A machined copper crucible is usually checked by material grade, dimensions, surface condition, and drawing consistency. For C10200 oxygen-free copper, a material certificate can support alloy identity. For custom parts, dimensional inspection is often more useful than a general certificate because the customer needs to know whether the part fits the equipment.

📑 Document	🧭 Purpose
Material Certificate	Confirms copper grade such as C10200
Drawing Confirmation	Confirms design before machining
Dimensional Inspection	Checks OD, ID, cavity depth and key features
Surface Photos	Shows visible finish before shipment
Packing List	Confirms quantity and package details
Commercial Invoice	Supports purchasing and customs clearance
Custom Label	Helps link parts to project or equipment number

🧾 If your company has a required inspection form, please send it with the inquiry. Some customers need only size and photo confirmation, while others require full dimensional records. Early confirmation prevents delays after the copper crucible has already been produced.

🧭 How to Request a Quotation

📨 To quote accurately, NiTiCu needs enough technical information. Please provide material grade, drawing or sample photo, outer diameter, inner cavity dimensions, total height, bottom shape, quantity, tolerance, surface requirement, and application. For e-beam use, equipment model or source pocket information is helpful. For water-cooled use, cooling structure and leak test requirement are essential.

🧩 Inquiry Information	💬 Example
