ABSTRACT:
A high-purity hard gold alloy containing 50 ppm or more of Gd and one or more of other additional elements in Au having a purity of 99.7% by weight or more, such that a total content of the additional elements is 100 to 3000 ppm. The high-purity gold alloy can be hardened to a level approximately equivalent to that of 18-karat gold at a relatively low working ratio, and the high-purity gold alloy thus hardened is not extremely softened by a heat treatment performed as a post-treatment, such as brazing or welding.
