Chuck Metals is a reliable manufacturer and supplier of high-purity copper products based in Singapore, Pulau Ujong. They offer top-notch Copper C10500 Bars and Rods, perfect for critical electrical, electronic, and industrial applications. C10500, also known as OFE Copper (Oxygen-Free Electronic), is celebrated for its outstanding conductivity and purity, making it a go-to choice for industries that need minimal electrical resistance and excellent formability. Chuck Metals provides copper rods and bars that meet precise tolerances, boast an excellent surface finish, and comply fully with international standards. With quick delivery and expert technical support, Chuck Metals ensures consistent performance for demanding copper applications.
The Copper C10500 Bars and Rods contain 99.99% pure copper with no residual oxygen, which gives them the highest electrical conductivity among commercially available copper grades—typically reaching ≥101% IACS. They also feature excellent thermal conductivity, low volatility, and remarkable ductility. In terms of mechanical properties, they have a tensile strength of about 220–300 MPa (when annealed), making them easy to machine, fabricate, and weld in sensitive applications. The lack of oxygen eliminates the risk of hydrogen embrittlement during high-temperature processing, which is vital for vacuum systems, electronics, and instrumentation that require absolute material integrity.
