CORSON ALLOY AND METHOD FOR MANUFACTURING SAME

摘要

Provided are a Corson alloy in which the occurrence of sagging is significantly reduced, and a method for manufacturing the Corson alloy. A Corson alloy containing 0.8 to 4.5% by mass of one or more of Ni and Co and 0.2 to 1.0% by mass of Si with the balance made up by copper and unavoidable impurities. The Corson alloy has a Young's modulus (bending flexure coefficient) in the 90-degree direction (where the degree represents the angle with respect to the rolling direction on the rolling plane of the copper foil; the same applies below) of 100 to 120 GPa, and the Young's modulus (bending flexure coefficient) in the 45-degree direction is no greater than 140 GPa.
