This has made Busby Metals’ aerospace-certified high-performance copper alloys the go-to option for companies like Boeing and Airbus for materials to build aircraft that lives truly depend on. Our expert consultants and deep experience give us the edge.
Our lineup of Aerospace-grade copper alloys includes:
Copper Beryllium C17200
One of the most popular high-strength copper alloys in the world, C17200 has superior attributes in nearly all areas, including Strength, conductivity, ductility, corrosion resistance, machinability, and formability.
C17200 has:
- Moderate thermal and electrical conductivity
- Low friction / anti-galling
- No magnetic interaction
- Superior resistance to erosion and corrosion
- The ability to anneal and re-age
Copper Beryllium C17510
An excellent option for electronic connectors and mold tooling, C17510 boasts extremely high conductivity properties while having very low friction. This makes it a good choice for high-demand electronics applications.
C17510 features:
- One of the highest yield to elongation ratios in electronics
- Excellent resistance to seawater and other corrosives
- Easy machinability
- Multiple tempers
Tellurium Copper C14500
Generally considered the easiest copper alloy to machine, C14500 seeks a balance between strength and conductivity. C14500 is perfect for electronic applications where large amounts of stress or frequent cycling may occur, while still being conductive enough for reliable electrical use.
C14500 copper alloy has:
- Improved strength
- Excellent conductivity
- Good formability
- Excellent ductility
Cupronickel CuNi14Al2
Cupronickel products are especially noted for their excellent resistance to corrosion, even beyond most other copper-based alloys. They’re widely used in both marine and aerospace applications, as well as their inability to produce sparks under any forms of impact.
Cupronickel CuNi14Al2 boasts:
- High impact resistance
- High strength
- Excellent corrosion resistance
- Moderate machinability
ToughMet 3 ® Spinodal C72900
This specialty wrought Copper-Nickel-Tin alloy has much the same strength as copper beryllium alloys, but with lower heat/electrical conductivity. This makes it an excellent alternative in scenarios where beryllium is undesirable.
C72900 features:
- High stiffness ratio
- Excellent bearing performance
- High strength
- Easy machinability
- High corrosion and erosion resistance
