Cast

Tin bronze alloys, such as C91600, are typically found in gear, high-strength bushing 天天斗牛bearing applications where low speeds 天天斗牛heavy loads are present. Other high-strength applications for these alloys include pump impellers, piston rings, steam fittings 天天斗牛valve bodies. C916 tin bronze castings are utilized in movable bridge components, turntables for bridges 天天斗牛other structures for fixed 天天斗牛expansion bearings with slow or intermittent movement with heavy loads.
