CNC Machining of Aluminum Alloy Shell

CNC Processing of Tin-Cobalt Alloy for Aluminum Alloy Shell


Tin-cobalt alloy electroplating and cobalt electroplating are similar in tone, but softer and more popular. At present, chromium is mostly used to replace chromium abroad. Electroplating cobalt is not easy for barrel plating, while electroplating tin-cobalt alloy can be used for barrel plating of small parts. In addition, tin-cobalt alloy electroplating has excellent uniform plating ability and barrel plating ability, so it can be applied to workpieces with complex shapes. If double nickel is plated on the bottom layer, its corrosion resistance is no less than that of chromium plating. In order to prevent surface discoloration, chromate impregnation is used to treat the surface, which can also improve its corrosion resistance.


Its appearance is pale rose tone, making people feel very comfortable, and has excellent corrosion resistance. Lustrous


Substrate or bright nickel plating, followed by tin-nickel alloy plating, can get a good glossy surface. If electroplating on the dull surface (pear grain), the original condition of the surface can be reproduced. The plating ability of the electroplating layer is very excellent, almost no leveling effect, so it is suitable for plating products requiring very fine lines and rotary processing.
