Overview

What Is CuZn40 Powder?

CuZn40 powder, also known as C28000 brass, is a brass alloy composed of approximately 60% copper and 40% zinc. This higher zinc content gives CuZn40 increased strength and hardness compared to other brass alloys like CuZn30. It’s often used in applications where mechanical strength and durability are critical, such as in heavy machinery, valves, and fittings.

The combination of copper and zinc in CuZn40 results in a material that is tough, wear-resistant, and capable of handling high-stress environments. Additionally, it has good corrosion resistance in non-aggressive environments, making it suitable for both indoor and outdoor applications.

Key Features

• High Strength: With a higher zinc content, CuZn40 offers greater tensile strength and hardness.
• Good Machinability: Can be easily machined and fabricated into complex parts.
• Corrosion Resistance: Performs well in non-aggressive environments, making it suitable for marine and industrial applications.
• Ductility: Though less ductile than CuZn30, CuZn40 still offers reasonable ductility for forming and stamping processes.
• Cost-Effective: Due to its high zinc content, CuZn40 is often more affordable than other copper-rich alloys.

CuZn40 Powder Composition

Understanding the composition of CuZn40 powder is key to understanding its mechanical properties and applications. This alloy is primarily a combination of copper and zinc, but small amounts of other elements may also be present to enhance specific characteristics.
