Alloyed bronze welding wire for ampcoloy alloys. Very good
heat conductivity. Beryllium Copper is the most commonly
utilized Copper Beryllium alloy and is notable for its highest strength and hardness compared to commercial copper
alloys. BeCu25 alloy contains appr. 2% of beryllium and
achieves its ultimate tensile strength can exceed 200 ksi,
while the hardness approaches Rockwell C45. Meanwhile,
the electrical conductivity is a minimum of 22% IACS in the
fully aged condition.
