Chuck Metals is a reliable manufacturer and supplier of Beryllium Chromium Copper Bars and Rods based in Singapore, Pulau Ujong. They provide high-strength, high-conductivity materials that cater to the aerospace, automotive, electronics, and tooling industries. This advanced copper alloy boasts an impressive mix of mechanical strength, electrical and thermal conductivity, along with resistance to wear and corrosion. Chuck Metals offers Beryllium Chromium Copper in precision-forged and machined bar and rod forms, adhering to international standards like ASTM B441 or B534. With a strong emphasis on material traceability, dimensional accuracy, and quick delivery, Chuck Metals has established itself as a trusted partner for top-notch copper alloy solutions.
Beryllium Chromium Copper Bars and Rods mainly consist of copper (~97.5%), beryllium (~1.8–2.0%), and chromium (~0.3%), merging the strength of beryllium copper with the enhanced thermal and corrosion resistance provided by chromium. This alloy achieves a tensile strength of up to 1400 MPa (after heat treatment) and retains electrical conductivity of up to 45% IACS. It also features high hardness (~38–44 HRC), good fatigue resistance, and excellent dimensional stability under thermal cycling, making it perfect for complex, high-performance applications.
