Chuck Metals is a trusted and seasoned manufacturer and supplier of top-notch metal products, proudly based in Singapore, with a robust distribution network throughout Pulau Ujong. The company is dedicated to providing precision-engineered materials, offering a diverse selection of copper and copper alloy products designed for industrial and electrical uses. One of their standout products is the Copper C11400 Bars/Rods, renowned for their exceptional machinability and impressive thermal and electrical conductivity. With a commitment to consistent quality control and prompt delivery, Chuck Metals caters to vital sectors like electrical, electronics, plumbing, and general engineering, delivering reliable solutions that meet rigorous technical standards.
The Copper C11400 Bars/Rods are primarily made of copper (over 99.9%) with a slight addition of sulfur (0.02–0.04%), which greatly enhances machinability without sacrificing conductivity. These bars boast excellent thermal conductivity, high electrical conductivity (over 90% IACS), and good resistance to corrosion. The sulfur addition provides free-cutting characteristics, making them perfect for high-speed machining tasks. C11400 strikes a balance between strength and formability, with moderate tensile strength typically ranging from 250 to 400 MPa, depending on the temper. These mechanical and physical attributes make C11400 ideal for components that require precise dimensions, clean finishes, and reliable electrical performance.

Copper C11400 Bars and Rods have good thermal conductivity but are not ideal for high-temperature applications. They are best used at temperatures up to 200°C to prevent softening and degradation.
Yes, Copper C11400 Bars and Rods are fully recyclable. The material retains its properties after recycling, making it an eco-friendly option for sustainable industrial use and reducing environmental impact.
Copper C11400 Bars and Rods are naturally resistant to corrosion in many environments. However, in harsh conditions such as marine or acidic environments, additional protective coatings may be recommended.
Copper C11400 Bars/Rods find extensive use in industries where outstanding machinability and conductivity are crucial. In the electrical and electronics fields, they are utilized for terminals, connectors, switch components, and bus bars, thanks to their high conductivity and smooth finish post-machining. In plumbing and HVAC systems, they are used for fittings and valves where corrosion resistance and formability are key. Additionally, they are employed in industrial equipment that requires precision-turned parts, such as fasteners, pins, and threaded components. C11400’s versatility makes it a go-to choice for various applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
