Introduction
Copper alloys are available in more than 400 varieties. Each type of
copper alloy has specific properties that suit a number of
manufacturing processes, environments and applications. Some of the
copper alloy forms include:
- Beryllium copper
- Nickel silver
- Tin bronze
- Brass
- Phosphor bronze
- Gunmetal
- Aluminum bronze
- Copper-nickel
