Overview
C81500, known as chromium copper, is a unique copper alloy that bridges the gap between high conductivity and robust mechanical properties. The addition of chromium to the copper matrix significantly enhances its strength and hardness without significantly compromising its electrical and thermal conductivity. This makes C81500 an excellent choice for applications where both conductivity and durability are essential, such as electrical contacts, resistance welding electrodes, and structural components in electrical systems. Furthermore, it exhibits good wear resistance and corrosion resistance, ensuring long-term performance and reliability in demanding environments. This combination of properties makes C81500 a valuable material for applications requiring a balance of conductivity, strength, and resistance to wear and corrosion.
Typical Uses
Cams, fittings, flanges, forming rolls and dies, ordnance parts, shaft sleeves, steel mill nuts, worm gears. Other typical uses include hydraulic cylinder parts, heavy load bearings, hooks, large valve stems, struts, and rudders.
