Brush Wellman’s Alloy Products Group’s ToughMet copper- nickel-tin alloy has shown continued success in mining and offhighway machinery. And, according to the company, test results show that ToughMet bushings with solid lubricant inserts can be used as a dry replacement for oil-lubricated leaded tin bronze bushings. ToughMet is also a proven alternative to traditional transmission thrust-bearing materials without increasing frictional power loss or endangering mating components.
