18K gold is favored by jewelry artists because of its moderate flexibility, easy modeling, strong personality and expressive force, and becomes the first choice material for jewelry works of art ...
As a precious metal, gold has good physical properties. "Real gold is not afraid of fire" means that gold has high chemical stability and is not easy to react with other substances, so there is no need to worry about oxidation and discoloration.
Even in the molten state, it will not be oxidized and discolored, and it will still be golden yellow after cooling. High density and heavy touch. Good toughness and ductility, good electrical conductivity. Pure gold is bright yellow, but the color changes greatly after mixing with other metals, such as gold-copper alloy is dark red, and silver-containing alloy is light yellow or grayish white. Gold is easily ground into powder, which is also the reason why gold is dispersed in nature. Pure gold jewelry is also easy to wear and lose weight.
Extended data:
note:
1, gold has excellent ductility. 1 oz gold can be stretched to 50 miles long, and its ductility makes it easy to cast, making it a good choice for making jewelry. Of all metals, gold has the greatest pulling force.
2, the ductility is second to none. It will cause extremely thin gold sheets to roll up easily. Gold weighing 1 ounce can be hammered into 1 foot thickness and 100 square foot thickness. The ancients hammered it into thin slices and spread it in temples and palaces for decoration. All these can show that gold is extremely flexible and plastic.
Although gold is a very soft metal, it is not as good as lead and tin. Nails can be used to draw marks on pure gold, which makes gold very easy to process.
