Abstract

PURPOSE: To make a Cu alloy equal to brass in strength and enhance the electric conductivity and the sensitivity of stress corrosion crack resistance of the alloy by adjusting the alloy to a composition contg. a small amount each of Co, P and one or more kinds among Ag, Sn, In, Mg, Mn, Zn, si and Al.
CONSTITUTION: This Cu alloy with high strength and high electric conductivity contains 0.1W2.0% Co, 0.01W0.5% P and 0.1W1.0% in total of one or more kinds among Ag, In, Sn, Mg, Al, Si, Mn and Zn except the balance Cu. since this alloy is equal to brass in strength and more superior than brass in electric conductivity and sensitivity of stress corrosion crack resistance, when it is used as a material for parts of electric and electronic apparatus, the reliability of the parts can be improved.
