SANKOL HG22K is a mild acid gold plating process that produces a 22 Kt gold alloy deposit. This system can operate within a wide current density range to provide a
mirror-bright deposit with a hardness range of 240-280 Vickers, up to 10 microns or more. The SANKOL HG22K deposit has a uniform color, is very ductile, and
corrosion-resistant, making it particularly suitable for jewelry or decorative applications. Both rack and barrel plating can use this process. It is highly stable and effortless to control.
