Description
🏆 Superior C36000 Brass Plate – Proven and Reliable ASTM B36 Brass Sheet
🧩 Product Overview
C36000 Brass Plate, also known as free-cutting brass or leaded brass, is a high-machinability copper-zinc alloy that includes a small percentage of lead to improve chip breaking and cutting performance. Composed of approximately 61.5% copper, 35.5% zinc, and up to 3.0% lead, C36000 is engineered for superior machinability, making it the standard choice for precision components requiring tight tolerances and smooth finishes.
This alloy conforms to ASTM B36 standards and is widely used in CNC machining, automatic screw machines, and mass production environments where high-speed cutting is critical. C36000 Brass Plate delivers excellent wear resistance, low friction, and good thermal conductivity, making it ideal for electrical components, valves, fittings, gears, and instrumentation hardware.
🔬 Chemical Composition of C36000 Brass Plate
| Element | Symbol | Typical Content (%) |
|---|---|---|
| Copper | Cu | 60.0–63.0 |
| Zinc | Zn | Balance |
| Lead | Pb | 2.5–3.7 |
| Iron | Fe | ≤ 0.35 |
| Total Impurities | — | ≤ 0.5 |
The lead content in C36000 Brass Plate is uniformly dispersed in the copper-zinc matrix, significantly enhancing tool life and productivity while ensuring smooth surfaces and reduced work hardening.

🛠️ Workability and Machining
✅ Machining
C36000 Brass Plate is considered the benchmark alloy for machinability. With a machinability rating of 100%, it is commonly used for:
- CNC-turned parts
- Milling and drilling operations
- High-speed production lines
It forms short, broken chips that do not jam tools, reducing tool wear and cooling system load.
✅ Forming
While C36000 is optimized for cutting, it also provides decent cold-forming capabilities:
- Stamping and blanking at high production rates
- Acceptable bending and pressing, especially in thinner gauges
- Hot forging is limited but possible with proper temperature control
✅ Joining
- Soldering: Excellent
- Brazing: Good
- Welding: Not recommended (due to lead)
