Title:
COPPER ALLOY THIN SHEET FOR PRODUCING CONNECTOR AND CONNECTOR PRODUCED BY THE THIN SHEET
Document Type and Number:
Japanese Patent JP3796784
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a copper alloy thin sheet for producing a connector not only excellent in tensile strength, elongation, electric conductivity and spring critical value, but also excellent in spring critical value after forming and ther mal creep characteristics and furthermore small in die wear in blanking and to provide a connector produced by the above copper alloy thin sheet.
SOLUTION: This steel sheet is composed of a copper alloy having a compsn. contg., by weight, 0.3 to 2% Mg, 0.001 to 0-02% P, 0.0002 to 0.0013% C and 0.0002 to 0.001% oxygen, and the balance Cu with inevitable impurities and having a structure in which oxide grains contg. fine Mg with ≤3μm grain size are uniformly dispersed into the matrix.
