METHOD OF EVALUATING BENDING WORKABILITY AND SPRING CHARACTERISTICS OF METALLIC MATERIAL, AND METALLIC MATERIAL

摘要

PROBLEM TO BE SOLVED: To find material characteristics having strong correlation with bending workability and contact pressure of a contact section, when the material is processed into a connector terminal with regard to a phosphor bronze, a titanium-copper alloy, and a Corson alloy. SOLUTION: The method of evaluating bending workability and spring characteristics of a metallic material is based on the difference between compressive proof stress and tensile proof stress in a direction parallel to rolling and the difference between compressive proof stress and tensile proof stress in a direction perpendicular to rolling.
