Beryllium Copper Spring Sheet

Beryllium copper combines elasticity, strength, durability, and conductivity. Due to its nonmagnetic and non-sparking characteristics, it can be used in applications involving potential hazards and high sensitivity in place of standard steel alloys. Furthermore, it can be used in marine and chemical environments as it resists corrosion, but it should not be used in environments with ammoniacal solutions, nitric acid, and acid chromate, and in high concentrations of ferric chloride, ferric sulfide, and other ferric compounds.

We provide beryllium copper spring sheets for different engineering purposes. Known for their versatility, our sheets can be formed or stamped into intricate patterns while maintaining impressive dimensional stability. Beryllium copper also demonstrates excellent resistance to precipitation hardening treatments. While beryllium copper spring sheets possess different mechanical properties in comparison to high-strength alloys, they most certainly stand to be one of the strongest variants of copper alloys.
