| titleOfInvention | Silver alloy product and jewelry and method for producing silver alloy product |
| abstract | [Objective] To obtain a silver alloy product having sufficient strength while maintaining the brightness of pure silver. [Configuration] near the surface from the surface 1a of up to 200 to 500μm depth of ring 1 made of silver alloy containing magnesium 0.2 to 2.0 percent by weight in the silver (jewelry silver alloy product) A surface hardened layer 2 having a hardness higher than that of the inner alloy 3 is formed in the region by a heat hardening process. The thermosetting treatment is performed in the air at a temperature of 550 to 800 ° C. for 30 minutes or more after being formed into a product shape with the silver alloy. As a result, a surface hardened layer 2 having a surface Vickers hardness of 200 to 300 Hv is formed, but the inner alloy 3 has a lower hardness and has a toughness close to that before the heat hardening treatment.
