Copper Pins

Our Copper Pins are made from ETP grade copper to ensure minimal resistance and maximum current carrying capacity. They are essential for high-performance electrical connectors, power distribution systems, and automotive electricals. Unlike brass, pure copper offers superior conductivity, making these pins ideal for applications where heat generation must be minimized. We machine these pins with specialized tooling to prevent burrs and ensure a clean finish. We can offer them in various tempers from soft to hard, allowing for crimping applications or rigid plug pins.
