Beryllium Copper C17500 Machining
Beryllium Copper C17500 Machined Parts
Sunhy has a reputation for machining quality parts from Beryllium Copper 175. We can machine intricate parts on our CNC Swiss machines and CNC turning centers.
Beryllium copper alloy 175 (BeCu) is a free-machining copper alloy, ideal for parts that require high strength and stiffness. It has excellent electrical conductivity. Beryllium copper is also suitable for environments that require high corrosion resistance, such as marine environments.
BeCu 175 has a machining cost factor of 1.5 when compared to steel 12L14. It is good for soldering, brazing, welding, and hot and cold working, but is not ideal for forging. BeCu 175 can be annealed.
