FORMING AND HEAT TREATMENT PROCESS FOR COPPER ALLOY ELECTRIC CONNECTOR MATERIAL AND COPPER ALLOY FOR ELECTRIC CONNECTOR MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a forming and heat treatment process for an electric connector material with spring properties and a copper alloy suitable for electric connector material.;SOLUTION: This is a forming/heat treatment process for a copper alloy used for electric connector components wherein heat treatment is provided subsequent to forming process. The electric connector alloy material is formed into a spring component maintaining the change in the hardness of spring portion less than 10 in terms of Vickers hardness (Hv) before and after it is formed. It is followed by heat treatment in which the change in the hardness of spring portion is maintained less than 10 in terms of Vickers harness (Hv) before and after the heat treatment. The heat treatment is preferably performed at the temperature range of 200-800 degrees Centigrade for 5-10,000 seconds.;COPYRIGHT: (C)2002,JPO
