Gold is a special reserve currency which is to be used to repay the debt, to promote and coordinate the national trade balance between the countries. Because of its excellent ductility and plasticity, in addition to exiting in the usual forms of gold bullion and gold blocks, gold can also be made of a number of exquisite handicrafts and fully loved by the people. But with the ups and downs of international situation, the declined gold price makes gold collectors gradually lost interest in it and turn their interests to the tungsten gold-plated collections. Tungsten gold-plated products are the high cost performance and high quality and cheap alternative collections which can well interested the expensive gold products.in collectibles.

 

Gold-plating process can be divided into electroless gold-plating and gold-plating. Electroless gold-plating is mainly used in the manufacture of semiconductors and printed circuit boards and plays an important role in the electronic plating. Whether it is a gold-plating or electroless gold-plating, both of them could be divided into non-cyanide gold-plating and cynide gold-plating. For now, the abrasion resistance, luster and adhesion of the products, made by the cyanide gold-plating, are better than the products made by non-cyanide gold-plating. The reason is that cyanide gold-plating has strong capability of cathodic polarization, dispersion and coverage. Since the existing essence of tungsten gold-plated products are to be used as collections and ornamental products, so the gold-plating process of tungsten gold-plated products mainly dependent on cyanide gold-plating, which will make the plating layers delicately and lightly with good corrosion resistance, abrasion resistance and good anti-tarnished capability.
