Composition of CuZn20 Powder

Understanding the elemental composition is essential for assessing how CuZn20 performs under different conditions. This alloy’s primary components, copper (Cu) and zinc (Zn), create a balance between ductility and strength.

요소구성 (%)합금에서의 역할
구리80Provides conductivity, corrosion resistance, and ductility.
아연20Increases strength, hardness, and wear resistance.

Why This Composition?
The high copper content gives CuZn20 its characteristic properties, while zinc’s presence enhances its hardness and resistance to mechanical wear. Compared to higher-zinc alloys, CuZn20 offers improved workability, making it ideal for precise, high-stress applications.
