Tin bronze alloys, such as C90810, are typically found in gear, high-strength bushing and bearing applications where low speeds and heavy loads are present. Other high-strength applications for these alloys include pump impellers, piston rings, steam fittings and valve bodies. C90810 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.
