Beryllium Copper Alloy (C17200 / C17510)
High-Strength Spring & Electrical Solutions by Huaxiao-Alloy
1. What Is Beryllium Copper?
Beryllium Copper (BeCu) is a high-performance copper alloy containing a small amount of beryllium, offering an exceptional combination of ultra-high strength, excellent electrical conductivity, and outstanding fatigue resistance. It is widely used in applications where mechanical performance and reliability are critical.
At Huaxiao-Alloy, Beryllium Copper is supplied as a precision-engineered solution, ideal for springs, connectors, molds, and high-end electrical components, rather than as a standard copper alloy product.
