C86300 copper pipe, also known as manganese bronze pipe, is a high-strength copper alloy primarily composed of copper, zinc, and a significant addition of manganese and iron. This specific composition grants it exceptional mechanical properties, most notably high tensile strength and superior wear resistance. As a result, it is a preferred material for demanding applications involving heavy loads, high stress, and significant friction, such as bushings, bearings, gears, and valve components in machinery and marine equipment.
Despite its strength, C86300 maintains good machinability and castability, allowing for relatively efficient manufacturing into complex shapes and precise parts. While it offers moderate corrosion resistance, particularly in marine atmospheres, its primary advantage lies in its durability under mechanical wear rather than in highly corrosive chemical environments. This combination of strength, wear resistance, and manufacturability makes C86300 pipe a critical engineering material in industries where component longevity and performance under pressure are paramount.
