Introduction

C86300 Thin Copper Sheet Metal

C86300 copper alloy, commonly known as high-strength manganese bronze, is a specialized material primarily used in demanding industrial applications where strength and wear resistance are paramount. Its key characteristics make it stand out as a premier choice for heavy-duty mechanical components.

The alloy offers an exceptional combination of very high tensile strength and hardness, which allows it to withstand extreme mechanical loads and shock. Furthermore, it possesses excellent wear resistance and anti-friction properties, classifying it as a “bearing bronze” ideal for high-load, low-speed environments. Despite its robust nature, C86300 maintains good castability and machinability, enabling the production of complex parts like gears, bushings, and heavy-duty bearings with relative ease and precision.

Applications for C86300 Thin Copper Sheet Metal

Heavy-Duty Bushings and Bearings

Its exceptional wear resistance and "bearing bronze" properties make it the premier choice for high-load, low-speed sleeve bearings, bushings, and thrust washers in industries like mining, construction, and marine engineering, where lubrication can be limited.

Gears, Pinions, and Worm Wheels

The alloy's unique combination of high strength, hardness, and good anti-frictional qualities against steel makes it ideal for durable gears, especially worm wheels in power transmission systems, where it provides quiet operation and long service life under heavy loads.

Wear Plates and Guides

C86300 is extensively used for manufacturing wear plates, liners, and guide rails in heavy machinery. Its ability to resist abrasion and deformation under constant pressure and sliding contact protects more expensive structural components from premature failure.

Valve Components and Hydraulic Parts

The material's high compressive strength, pressure tightness, and corrosion resistance suit it for critical components such as valve stems, hydraulic cylinder parts, and pump components that operate under high stress in corrosive environments like marine or chemical processing.
