This of precious metal materials gold, silver, platinum, etc. The jewelry is welded with metal alloy materials for non -precious metal materials, such as copper, zinc, etc., and the welding of jewelry welding.
The precious metal materials refer to eight elements of gold (AU), silver (AG), platinum (PT) 钯 (PD), oh (OS), 铱 (IR) 钌 (RU) 铑 (RH).
The most commonly used precious metal materials in the production and production of jewelry are gold, silver and platinum, and their alloy. The commonly used gold alloy is mainly 18K gold, 14K gold, 12K gold and 9K gold; the commonly used silver is 925 silver; Common platinum is platinum 900 (marked as PT900), platinum 950 (marked as PT950), and now the market has also begun to appear in the market (labeled PT990).
among these precious metal materials, the nature of platinum is the most stable, which has also become the pulse point for merchants in the jewelry market to promote platinum jewelry in the current jewelry market.

Bronze has strong wear resistance. Special brass is also called special brass.
