Aiman Metals provides high-machinability Copper C11400 Rods and Bars in Kuala Lumpur, Malaysia. Another name for “Free-Cutting Copper,” C11400 is a copper alloy with sulfur designed to have superior machinability without sacrificing conductivity. Suitable for automated screw machines and CNC lathes where accuracy and repeatability of dimensions are essential, Aiman Metals provides C11400 bars and rods in a wide range of sizes, tempers, and lengths for mass production or custom components. With stringent quality control and following ASTM B301 and other specifications, our products provide enhanced machining performance for a variety of industrial uses.
Copper C11400 comprises approximately 99.5% copper with 0.02–0.06% sulfur, which enhances machinability significantly. It gives approximately 90% IACS electrical conductivity and tensile strength of ~250 MPa in annealed condition. The alloy maintains excellent ductility and corrosion resistance but facilitates chip formation and tool life better than unmixed copper alloys. It‘s brazable and solderable, though welding is not usually advisable. C11400 provides superior surface finish in machined components and is therefore the first choice for precise copper parts.

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 Bar and Rod are used predominantly in high-speed machining applications such as plumbing fittings, electrical hardware, fasteners, gas valves, terminal connectors, and custom electrical components. It is best suited for automatic lathes, where quick turnaround and close tolerances must be achieved. The material is also applied in mechanical couplings, precision bushings, and grounding parts where conductivity and machinability must exist simultaneously. C11400 is selected where low tool wear, clean surfaces, and precise dimensions are required, thus finding applicability in small as well as high volume production in electrical and general manufacturing.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
