The B12 alloy, with the C90800 designation, complies with the key legislation that includes the Federal Safe Drinking Water Act 1974 - SDWA, the Federal Potable Water Reduction Act of 2011 and California Ab1953.

Material with good wear resistance, resistant to corrosion and salt water. CuSn12Ni2-C - GS and CuSn11Pb2 - GS materials were developed from this alloy. They are distinguished by greater stability and wear resistance, together with improved anti-friction properties.

Speed reducers, worm gears.

B12 tin bronze alloys, such as the C90800, are generally found in heavy duty gear, bush and bearing applications where there is high strength and low speeds and heavy loads. Other high strength applications for these alloys are pump impellers, piston rings, steam fittings and valve bodies. C908 tin bronze castings are used in components of movable bridges, turntables for bridges and other structures for fixed and expansion bearings with slow or intermittent movement with heavy loads.
