Authentic pure gold wire, diameter 1.0mm, au99.99%, electrophoresis cell electrode, 1g about 6-7cm, production deviation, settlement by weight.
Content and composition guarantee. Other sizes can be customized, generally produced in 2-3 days, standing 0.5mm 1.0mm off the shelf.
The diameter of the gold wire, i.e. its thickness, is exquisite. If it is a little less, its weight will be much less. This unit uses a milligram scale, i.e. one thousandth of a gram scale. It weighs the weight and sells it according to the weight, without any difference.
Common sense of gold:
Gold is the elemental form of chemical element gold (chemical element symbol AU), which is a soft, golden yellow, corrosion-resistant metal. Gold is one of the rarest, most precious and most valued metals. In the world, gold is generally measured in ounces. In ancient China, gold was measured in two units, which is a very important metal. It is not only a special currency for reserve and investment, but also an important material for jewelry, electronics, modern communication, aerospace and other sectors.
The chemical symbol of gold is Au, and the English code of finance is xauusd or gold.
Physical property
1. Color:
When gold is melted, the steam is green; during smelting, its gold powder is usually brown; if it is cast into a thin piece, it can transmit green light more.
2. Ductility:
Unusually strong. An ounce of gold can be pulled 50 miles long, and its malleability makes it easy to cast, making it a good choice for jewelry. Gold is the strongest of all metals.
3. Malleability:
come first on the list. It can make very thin and easy to roll up gold. An ounce of gold can be hammered as thin as 4 million feet and 100 square feet in area.
