C86200 is a high-performance copper-zinc alloy wire, commonly classified as a manganese bronze. Its primary distinction lies in its exceptional mechanical properties, which are significantly superior to those of standard brass alloys. The alloy achieves high tensile strength and outstanding wear resistance through a composition that includes copper, zinc, manganese, and iron. This makes C86200 wire an ideal choice for demanding industrial applications where components must withstand heavy loads, constant friction, and shock, such as in heavy-duty bushings, bearings, pump parts, and valve stems.
Beyond its strength, C86200 offers reliable corrosion resistance, particularly in marine and acidic environments, ensuring long-term service life. It also features good machinability for precision fabrication and excellent pressure tightness, preventing leaks in sealed components. Due to this combination of durability, wear performance, and environmental resilience, C86200 copper wire is a preferred material in sectors like shipbuilding, offshore engineering, heavy machinery, and aerospace, where failure is not an option.
