Neil Metals, based in Kolkata, India, has built a solid reputation as a leading manufacturer and supplier of top-notch Beryllium Copper Bars and Rods. We’re dedicated to providing high-performance copper alloys that are designed to excel in even the toughest industrial settings. Our Beryllium Copper products stand out for their remarkable strength, excellent conductivity, and impressive resistance to fatigue and corrosion. With rigorous quality control and a commitment to global standards, Neil Metals caters to a variety of industries, including aerospace, electronics, automotive, and tooling. Our reliable logistics, technical know-how, and focus on customer satisfaction make us a go-to partner for advanced copper alloy solutions throughout India and beyond.
Beryllium Copper is primarily made up of 1.8–2.0% Beryllium, with the rest being Copper, and it may also contain small amounts of Cobalt or Nickel. This alloy boasts a fantastic blend of high strength (up to 1400 MPa tensile strength), hardness (up to 45 HRC), and outstanding electrical and thermal conductivity. It’s known for its excellent resistance to wear, galling, and corrosion, maintaining its mechanical properties over a wide temperature range. Plus, Beryllium Copper Bars and Rods are non-sparking and non-magnetic, making them perfect for use in hazardous or precision-sensitive environments where reliability and safety are paramount.

Beryllium Copper Bars and Rods find extensive applications across various industries thanks to their high strength, conductivity, and non-magnetic characteristics. In the electronics field, they’re commonly used in connectors, switches, and semiconductor test sockets. The aerospace and automotive sectors rely on them for critical components like landing gear bushings, bearings, and high-stress springs due to their fatigue resistance. In oil & gas and mining, their non-sparking properties make them ideal for tools used in explosive environments. They’re also essential in precision tooling, molds, and instrumentation, where reliability is key.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
