Copper Base Alloys for Precision Investment Casting
Copper-base alloys have a predominant component of copper and are typically classified as brasses or bronzes. Brasses are copper alloys where zinc is the primary alloying addition. Bronzes are alloys in which tin is typically the main alloying element. They are commonly used for plumbing, marine and electrical applications because they provide excellent corrosion resistence, high thermal conductivity and toughness.
Additional benefits of using copper-base alloys include:
- Good castability
- Favorable mechanical properties
- Excellent machinability
- Friction and wear characteristics
