BERYLLIUM-COPPER, METHOD FOR PRODUCING BERYLLIUM-COPPER, AND APPARATUS FOR PRODUCING BERYLLIUM-COPPER

摘要

A method for producing beryllium-copper which contains at least Be and Cu, includes holding the beryllium-copper for a predetermined solid solution time in a solid solution temperature range in which Be is dissolved into the Cu; cooling the beryllium-copper at a cooling speed at which the Be remains dissolved in the Cu; applying plastic strain to a cooled beryllium-copper over multiple times in a processing temperature range in which the Be is not precipitated; and holding the beryllium-copper for a predetermined age hardening time in a precipitation temperature range in which the Be is precipitated.
