C17300 Beryllium Copper Bar

Product Description

C17300 Beryllium Copper is a high-performance, wear-resistant copper alloy renowned for its exceptional hardness, superior conductivity, and excellent tempering resistance. Its remarkable vertical stability ensures that thin sheets remain straight and resistant to bending, making it an ideal electrode material for aviation component processing.

 

This alloy boasts excellent processability and high thermal conductivity, along with outstanding welding, corrosion resistance, polishing, wear resistance, and anti-adhesion properties. It can be forged into various complex shapes, and its strength and wear resistance surpass those of chromium copper alloys, offering superior physical performance.

 

C17300 Beryllium Copper Bar contains a small amount of lead, which enhances its suitability for automated machining operations. The lead promotes the formation of finely divided chips, thereby extending the lifespan of cutting tools.

 

Composition

The typical composition of C17300 Beryllium Copper includes:

Beryllium (Be): 1.8 - 2.0%

Cobalt (Co): 0.20% min

Copper (Cu): Balance

 

Heat Treatment

C17300 can be heat treated to achieve higher strength and hardness. The process typically involves solution annealing followed by age hardening.

 

Standards

C17300 Beryllium Copper Bar conforms to various industry standards, including ASTM B196, AMS 4533, and CDA 173.

 

Machinability

The alloy has good machinability in the annealed condition, but it becomes more challenging to machine after heat treatment due to increased hardness.
