C90700 (SAE 65) Tin Bronze is primarily a gear bronze. It is strengthened by the solid solution of tin in the copper. This results in a strong, hard intercrystalline phase rich in tin. The tin atoms distort the copper matrix enough to help inhibit slip of crystal layers and the intercrystalline phase contributes to hardness. The tin bronzes do develop a low friction deposit of bronze on the mating steel parts. For this reason, tin bronze is the alloy of choice for nonferrous gears. Conforms to continuous cast specification ASTM B505
