Gold plating products
Jinyuan Kang electroplating gold according to its process characteristics, there is no cyanide gold plating and cyanide gold two. At present, the quality of gold plating is cyanide (potassium cyanide) gold plating as well, its color, adhesion, wear resistance are better than non-cyanide gold-plated. Function can increase the material's conductive properties. Gold-plated layer for the golden yellow, with high chemical stability, only soluble in aqua regia, insoluble in other acids. The atomic price of gold is one and three. The standard potential of a gold price is φ ° Au + / Au is + 1.68V and the standard potential of trivalent gold is φ ° Au3 + / Au is + 1.50V. For steel, copper, silver and its alloy matrix, the gold coating is the cathode coating, the pores of the coating affect its protective properties.
Jinyuan Kang gold plating layer of good ductility, easy polishing, high temperature, with good anti-discoloration performance. Silver plating on the silver layer can prevent the discoloration of silver; gold alloy coating can be a variety of colors, it is often used as decorative coatings, such as jewelry, watches and clocks, works of art and so on.
Jinyuan Kang electroplating gold has a low contact resistance, good electrical conductivity, easy welding, corrosion resistance, and has a certain wear resistance (referring to hard gold), and thus in precision instruments, printed circuit boards, integrated circuits, Shell, electrical contacts, and so has a wide range of applications.
