Copper-based deposited alloy strip for contact material and process for producing the same

摘要

A copper-based deposited alloy strip for a contact material has a maximum value of a difference not larger than 100 MPa among three of tensile strengths, that are a tensile strength in a rolling direction thereof, a tensile strength in a direction crossing the rolling direction with an angle of 45 degrees, and a tensile strength in a direction crossing the rolling direction with an angle of 90 degrees. A process for producing the copper-based deposited alloy strip for a contact material includes the steps of: performing a solution heated treatment on a copper alloy strip; and performing an aging heat treatment on the copper alloy strip.
