What silver is good; What kinds are there?

According to the purity of silver from high to low: foot silver, pure silver, silver plating, silver plating, containing silver ions.

1. Foot silver: Foot silver with a silver content of not less than 99%. National standards include Zuyin 990 and Zuyin 999 (note: silver with higher content than Zuyin belongs to silver raw materials, and the purity of finished silver is Zuyin 999). Thousands of feet of silver generally refers to 999 silver, and thousands of feet of silver generally refers to 9999 silver. Now the State Administration of Quality Supervision has cancelled the saying of "Thousand Foot Silver" and "Ten Foot Silver", which are collectively called "Foot Silver".

Features: Because the foot Ginta is soft, it is not easy to cast into the desired jewelry shape, and it is easy to wear and oxidize and blacken. So it is not suitable for jewelry. Many people pay more and more attention to the purity of silver, so now many craftsmen will choose the raw materials of silver according to different processes. For example, hammering, embossing and other processes are generally made of high pure silver, and carving and other processes are made of 925 silver. )

2. Pure silver: pure silver with a silver content of not less than 92.5%. This is also an internationally recognized standard for pure silver (and pure silver in our life usually refers to silver with a purity close to 100%, that is, silver with a silver content of over 925% in the finished product, including: pure silver 925, foot silver 990 and foot silver 999).

Features: Pure silver has ideal hardness, brightness, luster and oxidation resistance due to the addition of 7.5% alloy. But also can be inlaid with all kinds of precious stones, diamonds, jade articles and white stones. Since then, silver jewelry has become a new generation leader in the fashion world with its bright color, unique style, exquisite workmanship and moderate price.

3. Silver plating: Silver plating crafts are made by directly beating silver into thin slices and wrapping it on other metals or materials.

Features: the thickness is thicker than that of silver plating, and it is not easy to fade and wear, so the cost is higher and the price is more expensive than that of silver-plated jewelry.

4. Silver plating: Silver plating is to melt silver into liquid and then spray it on other metal surfaces, which is characterized by being extremely thin.

Features: low cost, and the jewelry made is easy to fade, such as sweat, acid and alkali. It can make the surface of jewelry silver-plated and oxidized, and wear quickly.

5. Containing silver ions: As the name implies, it is a product containing silver ions. (Silver ions are generally prepared by electrolysis)

Features: Silver ions are positively charged cations formed by the loss of one or more electrons of silver atoms, such as Ag+ and Ag2+? , Ag3+, etc. It usually exists in the form of aqueous solution, and silver ions have the function of sterilization and disinfection. Commonly used in: water purification, medicine, skin care products, daily necessities and other fields.

Second, what is the best silver?

Judging from the silver content, the finished product of 999 pure silver is better, while the purity of practical utensils such as silver pots, silver tea sets and silver tableware is better than 99%, that is, the silver content is above. Moreover, the higher the purity of hand-made, the more conducive to beating.

From the production process and style, 925 silver is far superior to 999 pure silver. The international standard purity of finished silver jewelry is 92.5%, with bright color, unique style, exquisite craftsmanship and leading the trend.

Silver plating and silver plating also have their own unique processes, and silver ions are more widely used.

It can be summarized in one sentence. There is no best, only the most suitable. The use and technology of each product determine the different uses of silver. I hope every product can be worth the money. I hope today's sharing will help you. See you next time.

I am the most beautiful woman, just for you to know how to hide the pot.

I have a silver pot that is enough to comfort my leisure. Watch the flowers bloom and fall, and enjoy the scenery of the four seasons.
