Abstract
There is provided a machinable .alpha.+.beta. brass containing bismuth and phosphorous. By maintaining the phosphorous content within a critical range, the alloy exhibits good elevated temperature tensile elongation in the temperature range of 100.degree. C.-350.degree. C. without a decrease in machinability due to phosphide formation. In preferred embodiments, the alloy further contains a tin addition for enhanced corrosion resistance. The combination of tin and phosphorous provides enhanced corrosion resistance to the alloy than could be predicted from either addition alone.
