What is the difference between gold and gold? What is the difference between gold and gold

Pseudo gold, an imitation gold alloy. Copper, lead, zinc, nickel, tin, etc. are the main materials, and there are many new imitation gold materials with copper as the matrix. Jewelry made of gold has a similar appearance and luster to 18K gold, and the texture is also similar to K gold, which has the advantage that the resistance to human sweat and air pollution corrosion is better than that of brass, but it is still lower than **, so it is called Yajin.

Yajin has a different formula and a slight difference in color. For example, when copper is 87 5%, zinc is 12 5%, or copper is 86 5%, zinc is 12 5%, and tin is 1%, it is golden red; 75% copper, 22% zinc, 2% tin, 1% lead, light golden yellow; Copper 58 5% 68 5%, Zinc 30% 40%, Tin 1 5%, or Copper 90%, Aluminum 7%, Nickel 3%, golden yellow; Wait a minute.

Yajin material is this year in China to develop the successful development of excellent imitation gold materials, it issued by the State Science and Technology Commission and entrusted to the Ministry of Light Industry to organize the relevant scientific research units and factories to develop, this scientific research achievements have been awarded the third prize of Shanghai Science and Technology Progress Award.

**(Gold) is the elemental form of the chemical element gold (chemical element symbol AU), which is a soft, golden-yellow, corrosion-resistant ***. Gold is one of the rarest, more precious and most highly valued metals. Internationally, it is generally measured in ounces, and in ancient China, it was "two" as the unit, which is a very important metal.

It is not only a special currency for reserves and investment, but also an important material for the jewelry industry, electronics industry, modern communications, aerospace industry and other sectors.

The chemical symbol is AU, and the financial English is XAU, or the name comes from a story of Aurora, the goddess of dawn in Roman mythology, which means shining dawn.

Yajin is not **, it is an imitation gold alloy. It is a new type of gold-like material with copper, lead, zinc, nickel, tin, etc. as the main materials and copper as the matrix. Jewelry made of gold has a similar appearance and color to 18K gold, and the texture is also similar to K gold.

Yajin is a metal-like material, mainly copper, lead and zinc, and its appearance is similar to **18K.

**The higher the purity of the jewelry, the darker the color. In the absence of a gold medal, the general fineness can be determined according to the following colors (based on lapis and gold. The so-called lapis gold is**contains only **ingredients):

The color of dark red yellow is more than 95%, light red yellow is 90% 95%, light yellow is 80% 85%, blue yellow is 65% 70%, color blue with white light is only 50% 60%, and light yellow and white is less than 50%. The commonly said seven green, eight yellow, and nine red can be used as a reference.

There is a difference between Yajin and **, and the deposit is more valuable than **I am**. Better, the gold content is more meaningful.

The purity of the mainland's ** jewelry is not very good, and the purity of Hong Kong** is much better than that of the mainland. If you want to buy a better purity**, Hong Kong Chow Tai Fook**, the mainland's Lao Fengxiang is also OK. Yayi **** You can buy a purity of 99%, which is marked in these gold stores.

Yayi, China's top ten ** jewelry brands, China's 500 most valuable brands, the quality will not be bad.

Yayi**'s reputation is not bad, and I haven't heard of any adulteration for the time being.

Can you elaborate on that a little bit more?

Yayi is also a time-honored gold store, which is still more reassuring. Yayi's reputation is not bad, I haven't heard of any adulteration for the time being, Yayi is still China's top ten **Qinkongsen jewelry brands, China's 500 most valuable brands, and the quality will naturally be poor sooner. And in the past few years, it has been uneventful, and it is also a good choice to buy it for investment.

Yajin is a man-made metal made of a variety of metal alloys, so it has high strength and corrosion resistance, and it is relatively low. Compared with **, the specific gravity of Yajin is lighter, the texture is not hard enough, the surface is easy to be scratched, and it is difficult to recover. Due to the different alloy compositions of gold, its color will also vary, for example, silver gold will look more similar to white gold, while red gold will appear more eye-catching.

It is a natural metal, named after its yellow color, which is more valuable and stable than Yajin. It has been used as a currency and wealth reserve for thousands of years, weighs about 19 grams per square centimeter, is dense, has a hard texture, and the surface is not easily scratched, and it is easy to melt and manufacture. In addition, it can also be used for jewelry, round ornaments and investment, and it is relatively high in the international market due to its scarcity and value.

Mainly used in industry and manufacturing, Yajin has low cost and high intensity, while **has investment and reserve value, and is able to obtain high transactions in the market**. Of course, there are other aspects to the difference, but the above elaboration can give everyone a simple idea of the pants.
