BECOL-25®
2% Beryllium Copper Alloy ASTM B196: C17200
We stock Beryllium Copper Round Rod in a
comprehensive range of sizes up to 12"dia
BECOL-25® is supplied solution heat treated for optimum workability
prior to precipitation
hardening by the customer to develop the full strength and hardness.
BECOL-25 contains around 2% beryllium and 0.4% cobalt/nickel and is capable of attaining the highest strength and hardness of any commercially available copper based alloy.
