Chung Metal supplies Copper C11300 Bars and Rods, a copper alloy with good machinability and intermediate strength. It is also known as “high-machinability copper” with minute additions of lead to enhance chip breaking and surface finish on machining. Our C11300 products are well suited for applications that call for both electrical performance and high-speed machining accuracy.
C11300 is composed of ~99.5% copper and 0.4–0.7% lead. Its conductivity is approximately 85–90% IACS. The tensile strength is between 250–320 MPa; yield strength ~100–150 MPa; elongation is approximately 20–35%. It possesses very good machinability (rated ~85–90%) and average corrosion resistance.

Copper C11300 Bars and Rods naturally resist corrosion due to their high purity and deoxidized composition. However, in harsh or aggressive environments, additional protective coatings may be applied for enhanced durability.
Yes, Copper C11300 Bars and Rods are fully recyclable. Copper maintains its properties after recycling, making it an eco-friendly material for reuse in various industrial applications.
Copper C11300 Bars and Rods can be used for potable water applications due to their corrosion resistance and non-toxic properties. However, local regulations should be checked for specific usage requirements.
Typically applied in machined electrical connectors, screw machine components, pins, terminals, bushings, and plumbing fittings. Its simplicity in machining renders it economical for mass production. Also used in precision components where good conduction and close tolerance are crucial.
