Tin Bronze Bushing For Mining Equipment uses high-purity copper as the base material, and ...
Copper alloy Worm Gear For Engineering Machinery Turbine is specially designed for engineering machinery (such as turbochargers, hydraulic drive systems, heavy-duty steering mechanisms, engineering drilling rig power heads, etc.), providing reliable power transmission and precise motion control in high-impact, high-temperature, and dusty environments.
1. Special copper alloy materials - rigid demand for engineering machinery
Material selection:
High-strength aluminum bronze (ZCuAl10Fe4Mn2): tensile strength ≥800MPa, high temperature resistance (≤350℃).
High-lead tin bronze (ZCuSn10Pb10): lead content 8-12%, excellent self-lubricating properties.
Core characteristics:
Anti-bite: prevent steel worm gears from adhesive wear during frequent start-stop.
Friction reduction and wear resistance: hardness HB190-220, wear amount in dusty environments is 40% lower than that of steel gears.
Vibration absorption and noise reduction: reduce equipment operating noise by 3-5dB (key to cab comfort).
