C86200 is a classic copper alloy hailed as “high-strength manganese bronze.” It is renowned for its remarkable mechanical properties—after heat treatment, it achieves strength and hardness exceeding that of ordinary steel, with a tensile strength easily surpassing 690 MPa, while retaining the inherent corrosion resistance of copper-based materials. This alloy exhibits excellent wear resistance under low-speed, high-load conditions, making it an ideal choice for manufacturing wear-resistant structural components such as ship propellers, heavy gears, and critical bearings.
Even more remarkable is the exquisite balance between its robust physical properties and excellent processability. Before heat treatment, it possesses excellent forgeability and machinability, facilitating machining and forming; after quenching and tempering, the material can still undergo precision grinding and surface treatment. This “shape first, strengthen later” characteristic allows it to handle complex component machining and provide long-term stable service under harsh conditions such as marine environments and heavy-duty machinery, making it a classic material solution in engineering that balances performance and durability.
