CU-MG-P BASED COPPER ALLOY MATERIAL AND METHOD OF PRODUCING THE SAME

摘要

PURPOSE: A Cu-Mg-P based copper alloy material and a producing method thereof are provided to balance the tensile strength and elstic limit of the Cu-Mg-P based copper alloy material with a high level. CONSTITUTION: A Cu-Mg-P based copper alloy material comprises Mg 0.3~2 weight%, P 0.001~0.1 weight%, Cu, and inevitable impurities. The area rate of crystal grains is 45~55% of the measured area of the Cu-Mg-P based copper alloy material. The tensile strength of the copper alloy material is 641~70 N/mm2. The elastic limit is 472~503 N/mm2.
