Beryllium Copper (BeCu), also known as Copper Beryllium and Beryllium bronze, is one of the highest strength copper-based alloys available on the market today. The industrial-grade of beryllium copper contains 0.4%-0.2% beryllium. The alloys are also non-magnetic and non-sparking, so they provide many ideal materials in many applications.
Advanced Refractory Metals is a leading supplier of beryllium copper products. We offer competitive pricing and great lead times on all our materials, and we’re capable of supplying custom materials per any specs/drawings you provide us with.
