What's the craft of the old temple e5 gold 999?

Old Temple e5 pure gold 999 is a cyanide-free hard gold process. Cyanide-free hard gold is the abbreviation of three dimensions. The gold content of cyanide-free hard gold is 999, which is also called hard pure gold. Cyanide-free hard gold is a new technology, which is essentially pure gold. Unlike Laojin, cyanide-free hard gold is sold directly as finished products. The purity of metal prepared by electrolysis is quite high.

Characteristics of pure gold

Cash nano-electroplating technology is adopted, and the improvement of molding process makes gold more three-dimensional. Through the application of space dewaxing technology of cash, its finished jewelry can be formed at one time, without solder joints and seams, with smooth and perfect surface lines and three-dimensional modeling. Through the application of different processes such as polishing, grinding and wire drawing, it shows the effect of contrast between light and shade, highlights different textures, and is fashionable and lovely.

By improving the working temperature, PH value, organic brightener content and stirring speed of electroforming process, the traditional crystallization mode of gold is changed, and the hardness of gold is improved by changing the arrangement order of gold atoms, while ensuring that only the molding process is changed, but the purity of gold is not changed. The hardness of cyanide-free hard gold is four times higher than that of pure gold, and the process is expensive.
