CR FREE CU ALLOYS AND ITS MANUFACTURING METHOD WITH HIGH ELECTRICAL CONDUCTIVITY AND HIGH TENSILE STRENGTH

摘要

PURPOSE: A copper alloy without chrome including high electrical conductivity and high tensile strength and a manufacturing method thereof are provided to obtain an environment-friendly metal. CONSTITUTION: A copper alloy without chrome including high electrical conductivity and high tensile strength contains 0.3~0.9 weight% of iron, 0.1~0.6 weight% of cobalt, 0.01~0.10 weight% of magnesium, 0.1~0.5 weight% of phosphorus, and copper. The conductivity of the copper alloy without chrome including high electrical conductivity and high tensile strength is over 75% IACS. The room temperature tensile strength of the copper alloy is over 530 mega pascals.
