Title:
MANUFACTURE OF COPPER ALLOY
Document Type and Number:
Japanese Patent JP2618560
Kind Code:
B2
Abstract:
PURPOSE: To manufacture a precipitation hardening copper alloy in which high strength and excellent transformation property are provided by executing a prescribed solution treatment and aging after the copper alloy of a regular alloy composition consisting of Ni, Sn and Cu is cast.
CONSTITUTION: A starting raw material is a copper alloy containing 2-10% Ni, 2-12% Sn, wherein the composition ratio of Ni to Sn is preferably 0.3:1 to 1:1 or 2-9% Ni, 6-10% Sn, 0.05-0.6% Mn, the balance Cu and regular impurities. The copper alloy is cast into a block or after being cast in a strip, is cold-rolled. Then, after the copper alloy is solution-treated at 650-800°C for 3-24 hours, it is cooled, preferably, rapidly cooled. Thereafter, the copper alloy is aged at 260-380°C for 15 minutes to 14 days and then, cooled in air.
