Beryllium Copper C17300 Machining

Beryllium Copper C17300 Machined Parts

Cox Manufacturing has a reputation for machining quality parts from Beryllium Copper 173. We can machine intricate parts on our CNC Swiss machines and CNC turning centers.

Beryllium copper alloy 173 (BeCu) is a free-machining copper alloy, ideal for parts that require very high strength and stiffness. It has excellent electrical conductivity and is one of the highest strength copper alloys. Beryllium copper is also suitable for environments that require high corrosion resistance, such as marine environments.

BeCu 173 has a machining cost factor of 1.0 when compared to steel 12L14, making it a better economic choice than BeCu 172. It is good for soldering, brazing, welding, and hot and cold working, but is not ideal for forging. BeCu can be annealed.
