K represents K gold (or open gold), which is a alloy made of gold and other metals. k gold's "K" is the writing of the word "karat" of the foreign language. The comprehensive statement: Karat Gold (that is, K gold), "AU" or "G" is a symbol used internationally to represent the purity (that is, the gold content). k gold jewelry is characterized by small gold volume, low cost, and can be made into various colors, and it improves hardness and is not easy to deform and wear. K gold is divided into 24K gold, 22K gold, 18K gold, 9K gold, etc.
The expansion information: K gold characteristics: one of the characteristics of gold is high ductility, so it is difficult to inlay various exquisite styles, especially when inlaid pearls, gems and gems and gems and gems Emerald and other treasures are easily lost. Therefore, people add a small amount of silver, copper, zinc and other metals to gold to increase the strength and toughness of gold. The gold jewelry made, also known as K gold. k gold can be prepared into various colors as needed. There are various colors of K gold jewelry popular in the world. Everyone is common in yellow and white. Mixing 25%of 入 or nickel in gold will become white, which is the main ingredient of it is gold. This is called white K gold. For science and technology, it is not possible to refine pure gold materials with a purity of 100%. Therefore, the golden position standard K in the gold content in the gold product generally refers to the pure gold as 24K gold, but it only contains 100%in theory, but it does not exist. So in national standards, the gold content of the merchants that the gold jewelry must not use the irregular standard method of "24K gold". Since the pure gold is 24K, that is, the theoretical gold content is 100%, then 1K means that gold products contain pure gold 1/24, about 4.16%. 18K gold represents the gold content of 18/24, which is 75%of pure gold, and the rest are other materials such as silver or copper. The gold jewelry contains other metals. Regarding the color content of gold products, the national standards have clear regulations, that is, each gold jewelry sold by merchants must be listed to indicate its gold content and weight. The weight of the gold jewelry is all using the national statutory unit. Its gold content should use "K gold" (excluding 24K gold), "foot gold" (not less than 99%), "thousands of gold" (not less than 99.9%). Pure gold "" 24K gold "and other" 24K gold "and other irregular standard methods. Reference information Source: Baidu Encyclopedia_k gold
Use K gold to represent gold content. The premise is that 24K gold indicates that the gold content is 1, which is 100 %. 18K gold indicates that the gold content reaches 75 %, and 19K gold means between 79, 16 and 79, and 17 % of the gold content. The gold jewelry sold on the market is divided into foot gold and K gold jewelry: According to the national standards, the content of several common gold jewelry is: 24K market occasionally marked with 24K gold jewelry. According to national standards, the theoretical value of 24K gold content should be 100 %, and gold is not red. Therefore, 24K does not exist. The content of thousands of gold is 99, 9, commonly known as three 9. Foot gold content is 99, 0, above, commonly known as two 9.
It refers to the gold content ratio on the ring. Pure gold is 24K, and 18K means that there are no 18 miles of gold (the rest are zinc, copper) because we know that the pure gold texture is relatively soft, and the wear is more powerful after long use. Therefore, some metals of intensity are added, and then processed into alloy to increase the overall strength and toughness. Makes gold is not easy to wear, and the price will be cheaper.
