Beryllium Copper C17200
Beryllium copper alloy 172 (BeCu) is one of the highest strength copper alloys, ideal for parts that require high strength and electrical conductivity. It has excellent corrosion and galling resistance. Beryllium copper 172 is also non-magnetic and has a very low permeability, making it a suitable choice for magnetic housings.
BeCu 172 has a machining cost factor of 3.0 when compared to steel 12L14. It is good for soldering, brazing, forging, welding, and hot and cold working. BeCu 172 can be annealed.
Industries & Applications
- Electrical contacts
- Bushings
- Bearings
- Pump components
