Palladium is one of the platinum group elements. This metal is hard and looks like platinum. It can present a silvery metallic luster and has the advantages of high temperature resistance, corrosion resistance, wear resistance and strong ductility.
Palladium is a platinum group metal, which is regarded as a substitute for gold or platinum by jewelry connoisseurs. Its catalytic performance makes palladium a very valuable metal in automobile industry.
Palladium has a natural pure white luster like platinum, and its color is bright. It also looks like platinum, but compared with platinum, the price of palladium is lower. Because palladium has some unique physical and chemical characteristics, it is more difficult to process jewelry than platinum, and the requirements for all links are very high.

In mineral classification, platinum group elements belong to natural platinum subgroup, including natural element minerals such as iridium, rhodium, palladium and platinum. And there is a wide range of isomorphic substitution between them, thus forming a series of isomorphic mixed crystals.
These elements are very similar in physical and chemical properties, especially palladium and platinum, which are as similar as brothers. The metallurgical properties of these two metals are very similar, because they are also rare and have similar uses, and they often replace each other in various applications.
