Use of palladium

What is the use of palladium? If you don't know, let's take a look! This article introduces palladium in several aspects, some physical properties and basic concepts of palladium, and some special uses of palladium.

Palladium is one of the rarest precious metals in the world and is much rarer than gold. Only a few countries in the world, such as Russia, North America and South Africa, produce. Jewelry made of palladium not only has the natural brilliance of platinum, but also lasts for a long time. Palladium has almost no impurities, and its purity is extremely high, shining with white light. The purity of palladium is also very suitable for the skin and does not cause skin irritation.

Palladium has excellent physical and chemical properties, high temperature resistance, corrosion resistance, wear resistance and strong stretchability. It can be replaced with platinum in purity, rarity and durability, whether it is made of jewelry alone or Inlaid with precious stones, it is the most ideal material.

The stamp of international palladium jewellery is "Pd" or "palladium" and is represented by the purity of thousands of digits. For example, Pd990 means purity is 990 ‰, palladium jewelry has different purity according to Pd900, Pd950, Pd990. Pd999 (thousands of palladium gold jewelry) with high purity is available.

Palladium has become a popular jewellery variety in the international market in recent years. In fact, as early as 1991, the International Organization for Standardization has released the "Provisions and Nomenclature of Purity of Precious Metals for Jewelry" including Palladium Jewelry. The Jewelry Standardization Technical Committee also provides information on national standards for palladium jewellery.

Like palladium, palladium, because of its scarce production, few origins, and uneven global distribution, often causes price changes due to certain special factors (such as the boom and decline of the auto industry, market intervention in a producing country, etc.). . It was once higher than the price of platinum in history. Palladium and platinum, gold and silver are the trading varieties of international precious metals spot and futures. Palladium and platinum have important applications in automotive exhaust gas treatment. So why did palladium jewellery wait until now?

This is because some special physical properties of palladium make the manufacturing process of palladium jewellery more complicated (for example, the casting process requires high vacuum). After years of careful research, the current technology and process are becoming more mature, and palladium can become a jewelry. There are two other important reasons why palladium jewellery is now fashionable. First, the price of platinum has been pushed up to the extreme, and it is getting farther away from the mass consumer. But the charm of this white metal has always attracted people, so the jeweler Created white 18K gold (this is a pale yellow alloy with 75% gold content and white metal plated on the surface).

White 18K gold jewelry looks similar to platinum jewelry, but the price is much cheaper. At the same time, the hardness of the alloy is slightly higher than that of platinum, which better meets the processing needs of jewelry processing. (The disadvantage is that after the gold jewelry is worn, the surface coating will wear out. Showing a light yellow color).

Palladium has a price advantage and has the same internal and external qualities as platinum. This is the essence that can partially replace platinum and K gold jewelry. Second, the density of palladium is lighter. Palladium with the same weight as platinum can have nearly 2 times the volume. Jewelry designers have provided a variety of materials for the design of the style, making the palladium jewelry more full, richer and more textured. With the improvement of the level of palladium jewellery manufacturing and the deeper understanding of the jewellery, in the near future, palladium will not only become fashionable in the form of jewellery, but also be admired in the jewellery.

The use of palladium is so extensive that it can also be used to treat automobile exhaust. It is believed that with the continuous development of technology, the use of palladium will be more extensive.
