Copper and copper alloys are versatile materials known for their excellent electrical and thermal conductivity, corrosion resistance, and ductility. Copper and copper alloy are some of the most versatile engineering materials available. The combination of physical properties such as strength, conductivity, corrosion resistance, machinability and ductility make copper suitable for a wide range of applications. These alloys are widely used in various industries, ranging from electrical wires to high-performance components in aerospace and marine environments.

Available grades

Brass: H59, H62, H65, H68
Beryllium copper: C17000, C17200, C17500
Cast beryllium bronze: C82000, C82200, C82400, C82500, C82600, C82800

Corrosion resistance
Choose alloys with higher corrosion resistance for marine or outdoor environments, such as bronze and copper-nickel alloys
Electrical/thermal conductivity
Pure copper or copper-silver alloys are ideal for applications requiring high conductivity
Strength and durability
For structural applications, stronger alloys such as aluminum bronze or brass are preferred
Machinability
For precision and large-scale manufacturing, leaded brass or machinable copper alloys are recommended for better machinability
