Description
High-Purity Copper Granules – 99.999% Cu
📦 Product Overview
The High Purity Copper Granules catalog lists 99.999% purity copper particles for material-processing enquiries. Specify particle form, size distribution, quantity, intended process and the required analysis basis. Use the ordered batch chemical report and particle inspection to select feedstock for laboratory work, melting or alloy production.
ASTM B170 is an oxygen-free electrolytic copper refinery-shape reference. Agree the final granule particle requirements, chemical analysis basis, sampling, packaging and acceptance documents for the intended process.
🔍 Material Composition & Purity Assurance
Confirm the 99.999% purity reporting basis and the required metal and nonmetal impurity limits in the order. Agree the applicable analysis methods, such as ICP-OES and gas analysis, with representative batch sampling and the requested chemical report.
Catalog Chemical Reference Values (wt%):
| Element | Symbol | Content (Max) |
|---|---|---|
| Copper | Cu | ≥ 99.999% |
| Oxygen | O | ≤ 0.0005% |
| Lead | Pb | ≤ 0.0005% |
| Iron | Fe | ≤ 0.0005% |
| Nickel | Ni | ≤ 0.0003% |
| Sulfur | S | ≤ 0.0003% |
The listed 99.999% Copper Granules are a feedstock enquiry route. Confirm the required analysis basis, impurity acceptance, particle condition and packaging with the material documents and quotation.

🏭 Manufacturing Process & Quality Control
1️⃣ Raw Material Selection
For the listed 99.999% purity route, specify the feedstock analysis basis and required impurity limits with the batch material documents.
2️⃣ Vacuum Melting
The copper is melted under vacuum or inert gas to avoid oxidation and minimize gas absorption.
3️⃣ Controlled Granulation
The molten copper is rapidly cooled and atomized to form uniform granules, achieving consistent particle size distribution.
4️⃣ Sieving & Particle Classification
Granules are screened to achieve the required mesh size, suitable for applications ranging from <1 mm to 10 mm.
5️⃣ Final Inspection & Packaging
Specify the required chemical analysis, particle inspection and any electrical checks for the intended process. Confirm the sampling and the listed vacuum-packed or sealed-container packaging with the quotation.
🔬 Key Applications
🧪 Laboratory Research – Ideal for metallurgical studies, alloy development, and thermal conductivity experiments.
Electronics material enquiries — define the downstream process, particle requirements and chemical acceptance before selecting copper feedstock.
🔩 Alloying Agent – Blended with other metals to create specialized alloys for aerospace, automotive, and marine industries.
Thermal-component feedstock — specify the downstream forming or melting process and the required material analysis.
Specialist material enquiries — state the component or process specification, impurity requirements and required inspection documents.
For copper supply and market background, consult U.S. Geological Survey copper statistics. Select granules using the required particle form, size distribution, assay basis and process acceptance criteria rather than a general market-demand forecast.
