Introduction

C86200 Thin Copper Sheets

C86200, commonly known as manganese bronze or high-strength yellow brass, is a high-performance copper-zinc alloy distinguished by its exceptional mechanical properties. Its primary characteristics are very high tensile strength, excellent wear resistance, and good hardness, making it far superior to standard brass alloys for heavy-duty applications. These properties stem from its unique composition, which includes significant additions of manganese, aluminum, and iron, contributing to its robust performance under stress and friction.

In terms of manufacturability, C86200 offers good machinability and excellent hot workability, allowing it to be effectively forged, extruded, or rolled at elevated temperatures. However, its high strength limits its ductility for cold-working processes. Combined with its inherent corrosion resistance and pressure tightness, these attributes make it a premier choice for demanding industrial components such as high-strength gears, heavy-duty bearings, valve stems, pump parts, and marine hardware.

Applications for C86200 Thin Copper Sheets

Heavy-Duty Machinery and Transmission Systems

It is a core material for manufacturing heavy-duty gears, worm gears, bushings, and high-pressure bearings, widely used in high-load, high-wear transmission components in mining machinery, heavy machine tools, and stamping equipment.

Marine and Marine Engineering

Due to its excellent resistance to seawater corrosion and cavitation corrosion, it is commonly used in the manufacture of critical equipment such as ship propellers, rudder bearings, seawater pump valve components, and offshore platform accessories.

Aerospace and Defense Industry

It plays a role in applications requiring high strength, wear resistance, and non-magnetic properties, used in aircraft landing gear bearings, helicopter rotor system components, missile parts, and wear-resistant structural components of certain special military equipment.

High-Pressure Valves and Pumps

Utilizing its high pressure resistance, excellent sealing properties, and corrosion resistance, it is used to manufacture critical fluid handling components requiring both strength and resistance to media corrosion, such as high-pressure valve stems, valve cores, pump housings, and plunger sleeves.
