Can. The gold jewelry can be divided into two categories: pure gold and K gold. K gold jewelry is a jewelry made of other metals (such as silver, copper metal) to its golden materials, also known as "opening gold" and "color gold". Due to the number of other metals, different K numbers of K gold jewelry are formed. k the size and gold content as follows: 24K, 99%or more; 22K, 91.7%; 21K, 87.5%; 18K, 75%; 14K, 58.5%; 12K, 50%; 10K, 41.66%; 9K, 37.5.5 %; 8K, 33.34%; 6K, 25%. Extended information: In gold jewelry, pure gold jewelry texture is soft, with a bite of the teeth and easy to bend. The color is golden, pure, soft, heavy, and has a heavy feeling. K -gold's head jewelry texture is slightly harder, the teeth bite the use of mintes, the color is yellow in yellow, and the number of K is reduced, the white increases, and the yellow is shallow. The feel of K gold jewelry is not as heavy as pure gold jewelry. In addition, both pure gold and K gold jewelry have a printing sign. The printing on the gold jewelry is useful "gold" and the "KG" English letters represent the texture. When indicating the gold content, the word "99" or "24K" indicates that it is pure gold jewelry. The K gold jewelry is marked with the corresponding K number, such as the K gold jewelry marked "18K". %. Reference materials Source: Baidu Encyclopedia-Gold Jewelry
Gold can be used to participate in jewelry together. The 22K gold and 18K gold we often say is the K gold jewelry made by gold copper to reduce the content of gold. It is also a copper gold alloy jewelry. The copper gold alloy production process is to put gold and brass in the melting furnace, melt them together with a high -temperature spray gun, and then pour into the plaster mold of jewelry. After cooling and molding , By polishing. Because the gold ginseng copper jewelry is made on the surface, it is not so bright or not as golden jewelry as golden jewelry. Generally, the copper gold jewelry will be placed in an electroplating groove to electrocated 24K gold. The jewelry is as beautiful as the golden. The gold jewelry of copper will increase, and the texture of pure gold jewelry is relatively soft.
No, gold is gold, copper is copper products, and the two products are mixed up with pure gold or pure copper, and the color of the copper is different from the color of gold. The hardness of the copper is relatively large. The hardness is small, and it is easy to break a little force, and the copper uses a large strength to break it during the process of breaking.
Copper: It pure copper is a soft metal. When the surface is just cut, it is red and orange with metallic luster, and the single matter is purple -red. Good ductility, high thermal conductivity and high electrical conductivity. Therefore, cables, electrical and electronic components are the most commonly used materials. It can also be used as architectural materials and can form many alloys. Copper alloy has excellent mechanical properties and low resistance, the most important bronze and brass. In addition, copper is also durable metal, which can be recovered many times without damaging its mechanical properties.
Gold:
The single -quality form of gold is a soft, golden, and precious metal. Gold is one of the rare, precious and most valued metals. Internationally, gold is generally based on ounces, and ancient China was used as a gold unit. It was a very important metal. It is not only a special currency for reserves and investment, but also an important material for the jewelry, electronics, modern communications, aerospace and air industry and other departments.
