Abstract

PURPOSE: To provide an age hardening Au alloy for decoration having excellent processing property and capable of obtaining high hardness containing Ni, Cr, Co and Zr respectively in a predetermined ratio and comprising the remainder of Au.
CONSTITUTION: An age hardening Au alloy for decoration contains 3W12wt% Ni, 0.3W1wt% Cr, 1W9wt% Co and 0.05W0.1wt% Zr respectively and comprises the remainder of Au. When said Au alloy is used as a watch with extremely high age hardening property, a thickness thereof can be made thin and said Au alloy contributed thinning. Further, when said Au alloy is used as a necklace, a finger ring or the like, they are hardly injured. Moreover, by altering an age hardening time, hardness thereof can be selected corresponding to a use.
