Abstract

The present invention relates to a white noble metal alloy combination, which comprises at least one of platinum and palladium which alloying with gold, siller and one or more choice additive alloy elements. Specifically speaking, in a specific way of implementing, the present invention discloses a white noble metal alloy combination which can be used to manufacture headgear and other products. In addition, the present invention also relates to a method for manufacturing finished products with such white noble metal alloy combination.

Description

technical field [0001] This invention relates to white precious metal alloy compositions. More specifically, in one embodiment, the present invention relates to white precious metal alloy compositions suitable for making jewelry and other finished articles. In addition, the present invention also relates to methods of making articles from the white precious metal alloy composition. Background technique [0002] The popularity of white gold has been steadily increasing in recent years, resulting in a corresponding increase in demand for platinum jewelry, especially in Japan and China. Platinum is especially popular due to its relative cheapness compared to platinum, as the public cannot easily distinguish platinum jewelry from platinum jewelry. In other words, for the wearer, platinum jewelry can maintain the aura and exclusivity of platinum jewelry at a greatly reduced price. [0003] Many jewelry manufacturers are able to create jewelry from platinum. In fact, platinum ...
