4 thoughts on “Platinum did not belong to gold. Why do precious metal platinum preferred to make jewelry?”

  1. Jewelry jewelry is a must -have tool for daily matching, and it is also the first choice for us to choose gifts. Friends who know more about jewelry in jewelry may find that most jewelery uses precious metals, and it is common, but gold and platinum. I believe it is not necessary to say more, everyone knows, but why is platinum often used as jewelry production? Let me take a look with you why Platinum is preferred by making jewelry.
    Platinum (English: Platium). Natural element platinum is a rare valuable metal element in the crust. The element symbol is PT. Because "platinum" is combined by the word "gold" and "white", and the color is silver -white, it is also called "platinum". Platinum has been widely used in the jewelry industry for about a hundred years. Its strength and antioxidant and the strong attraction of silver white color make it a practical and eye -catching metal. It is not only used for diamond inlaid, but also in various fine jewelry. Platinum is more rare than gold. The current price of platinum is almost twice gold. Generally, the pure platinum of 999 purity is rarely used to make jewelry because it is too soft as other metals. In most jewelry production, the platinum is a alloy, which is 95%platinum and 5%copper alloy. For AVIC cast alloys, 5%of copper are mixed with copper and cobalt. Other alloys that are generally recognized by the public are: 80%platinum and 20%alloy, 95%platinum and 5%alloy. When buying platinum, it is best to understand the composition of this alloy. Different alloys have different attributes, and suppliers usually tell you these.
    The processing technology of platinum jewelry is difficult, and the welding temperature of platinum is very high, which requires a special welding gun. It can use hybrid and propane mixed gases, or hydrogen and hydrogen hydrogen gases. When welding, you need to wear a special black protective glasses, because the strong yellow light emitted by metal at high temperature will burn people's eyes. When operating, platinum should be very clean. When platinum is in contact with metal tools, such as rolling, knocking, brushing, etc., it should be soaked in the thermal nitrate solution (the ratio of water and nitric acid is 10: 1) to ensure its purity. In addition, it is best to distille and clean up the operation tools before the operation of platinum. Any metal particles are deposited on platinum. When heating, it will be burned and leaves small holes on the surface of the platinum, and these small holes will be difficult to remove.
    In welding, it should be placed on a special welding chloroplasma platform, not all on the charcoal platform, because this will mix the carbon into the metal. Do not use ordinary tweezers for welding platinum operations. If it is necessary, the mule should be made from tungsten. Because platinum is not easy to be oxidized, the operation can be completed at a high level when welding. The welding point should be welded tightly and does not need to aid welding. In fact, welding agents may contaminate platinum due to silicon precipitation. Platinum can use high temperature welds, medium temperature welds or low temperature welds. A large welding point can put a small piece of platinum for welding. After welding, this platinum becomes the main part of the welding point and forms the work by grinding.
    During platinum processing, a set of knife should be prepared separately. If not, it should be polished before using other knife. Use 800, 1500, and 4000 fine polishing agents to polish the surface of the polished platinum. These polishing agents can be used for polishing paper, on the polishing machine, and is used for platinum polishing. The polishing agent should be used for white metal -general polishing with Hyfin, and a fine high -quality polishing with a green or white polished wax containing chromium or aluminum oxide.
    In the above content, do you have a deeper understanding of your precious metal platinum that made jewelry? For the production of jewelry, knowing the characteristics of these materials can better process and transform.

  2. Because platinum is rare, and the chemical properties are stable, corrosion -resistant, acid and alkali; shiny pure white is very beautiful, so it is the first choice for jewelry.
