Chung Metal Manufacturer & Suppliers in Da Nang, Vietnam, offers high-quality Beryllium Copper bars and rods for industries that demand high mechanical strength, good electrical conductivity, and corrosion resistance. Our beryllium copper stock is metallurgically processed to strict standards and shipped with certification and close dimensional control. Those needing a supply of beryllium copper rod for performance‑sensitive applications in electronics, tooling, aerospace, and safety environments count on us.
These alloys consist of ~1.8–2.1% beryllium in copper with small amounts of alloy additions (e.g. cobalt, cobalt + nickel) to maximize properties. Ultimate tensile strength as high as 1,300–1,400 MPa in peak aged or heat treated condition; also yield strength is high. Hardness at peak tempers is high (frequently in higher Rockwell or Brinell ranges), although elongation is smaller in hardest tempers (but still satisfactory in moderate tempers). Electrical conductivity reduces slightly in hardened conditions (typ. ~20–30% IACS or higher, depending on temper). Density ~8.25–8.36 g/cm³. High fatigue strength, wear resistance, and stability under cyclic loading.

To select the right Beryllium Copper bars, consider factors like strength, conductivity, corrosion resistance, temperature range, and machining requirements based on your specific application needs and environmental conditions.
Yes, Beryllium Copper rods are customizable in terms of length, diameter, and specific alloy grades, catering to various industrial applications like electrical, mechanical, and aerospace needs.
Used in springs, connectors for precision, relays, switch contacts, welding electrodes, mold inserts, non-sparking tools, bushings, and high reliability components. Also in oil & gas applications in flexible shafts, downhole tools, and connectors. Where conductivity combined with mechanical strength and resistance to corrosion or wear is necessary (instrumentation, broadcast contacts), beryllium copper bars and rods are a standard selection. Their mechanical, electrical, and thermal properties combined make them essential in numerous specialty uses.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
