At present, although the international palladium price is cheaper than that of platinum, in history, the international palladium price was about 3 yuan/gram higher than that of platinum (on November 6, 21, the international palladium price was as high as 1,94 US dollars/ounce). Palladium is one of the rarest precious metals in the world, and it is only produced in a few countries such as South Africa and Russia, with an annual total output of less than 5% of gold, which is even rarer than platinum. Platinum and palladium are the two minerals with the least reserves in the platinum group. Moreover, there are four major trading varieties of palladium, gold, platinum and silver in international precious metal spot and futures trading.
what makes palladium different
1. White gold is called K platinum and platinum, but it is actually an alloy. Its code name WG(White Glod) also means white gold. Generally, WG 585 (14k,) WG 75 (18k) is commonly used for foreign stamps; Or just represent the gold content by mathematics. White gold has good reflectivity and is not easy to lose its luster.
second, platinum is also called pure white gold. Its symbol is pt, silvery white, with a specific gravity of 21.35, a melting point of 1,7℃, a Mohs hardness of 4-4.5 degrees, chemical stability, and no acid and alkali corrosion except aqua regia. Pure platinum is soft, and the addition of metals such as palladium, rhodium and ruthenium will increase its hardness.
3. platinum Alloy refers to the alloy of platinum mixed with other metals, such as palladium, rhodium, yttrium, ruthenium, cobalt, osmium and copper. Although the hardness of platinum is higher than that of gold, it is not enough for inlay, and it must be alloyed with other metals before it can be used to make jewelry. The stamp of platinum ornaments in the world is the words pt,plat or Platinum, and it is represented by the number of thousandths of purity. For example, pt9 indicates that the purity is 9%. The specifications of platinum jewelry in the world are PD 1, PD 95, PD 9 and PD 85. < P > Fourth, palladium is a member of the platinum group, which is not easy to oxidize and lose its luster under normal conditions. Oxide will be produced on the surface at about 4℃, but it will regain its luster when the temperature rises to 9℃. At present, palladium is cheaper than platinum, which is used by jewelry industry alone or as a component of gold, silver and platinum alloys. To increase its hardness. Gold, palladium and alloys of platinum and palladium are common in the market.
palladium is more suitable for jewelry
palladium is relatively stable and can resist acid corrosion. Palladium has almost no impurities and its purity is extremely high. The purity of palladium is also very suitable for the skin, because unlike other metals, palladium will not cause allergic reactions to the skin. The international jewelry industry began to process palladium and platinum for jewelry and decorative works of art, and gradually formed a fashion trend.
palladium and platinum jewelry is stamped with the word "or" internationally, and it is represented by the number of thousandths of purity. For example, pd95 indicates that the purity is 95%, and the specifications of palladium and platinum jewelry are PD 1, PD and PD 85. Palladium jewelry products enjoy the same high-quality after-sales service as platinum.
