PURPOSE: To obtain superior strength, elasticity and electric conductivity and the like for wire harness terminal copper alloy by making Cu to contain, a specific ratio of Zn, Sn, Ni, and in some cases P.
CONSTITUTION: The copper alloy for the terminals of a wire harness is composed of Zn, Sn, Ni, and in some cases P in 5-15%, 0.5-3.0%, 0.1-1.0% and 0.01-0.1% by weight respectively, and the remaining of Cu and unavoidable impurities. Zn contributes to the improvement of strength, elasticity and heat resistance, and the copper alloy must contain at least 5% of Zn by weight. However, if the content of Zn exceeds 15%, electric conductivity and corrosion resistance are reduced. Sn helps to increase the strength, elasticity and other characteristics. However, if the content of Sn is less than 0.5%, the effect is not sufficient, and if it exceeds 3.0%, the electric conductivity and other characteristics are greatly reduced. Ni helps to increase strength, elasticity and other characteristics. At least 0.1% of Ni is needed to be effective. However, if the content exceeds 1%, the electric conductivity is greatly reduced. With the above composition, an alloy which excells in strength, elasticity, electric conductivity and also in moldability and corrosion resistance can be obtained.
