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