Starc Metals is a reputable manufacturer and supplier located in Canberra, Australia, with a focus on high-performance Beryllium Chromium Copper Bars and Rods. We pride ourselves on our dedication to quality, precision, and innovation, ensuring that our materials are engineered for outstanding conductivity, strength, and durability. Our products are made using cutting-edge manufacturing techniques and stringent quality control measures to meet international standards. We serve a variety of industries, including aerospace, electronics, and defense, guaranteeing reliable performance and top-notch material integrity. As a company that puts customers first, we offer tailored solutions to meet the ever-changing demands of modern engineering and manufacturing.
Beryllium Chromium Copper Bars and Rods are primarily made of copper (about 97.5–98.5%) with small amounts of beryllium (0.5–1.0%) and chromium (0.1–0.5%). This special blend gives them excellent thermal and electrical conductivity while boosting their strength and hardness. Depending on the temper, the alloy typically shows a tensile strength ranging from 700 to 1,400 MPa and can reach a hardness of up to 380 HV. It also boasts impressive wear resistance, fatigue strength, and thermal stability, making it perfect for tough industrial applications that require both conductivity and mechanical strength.
