The color of electroplating cobalt alloys is similar to electroplating cobalt, but it is softer and more popular. Most of them are currently used to replace chromium. Cobalt is not easy to roll, and tin -plated cobalt alloys can be used for small parts rolling. In addition, the cobalt alloys of the electricity and sinking tin have good uniform plating and rolling capabilities, which can be applied to complex workpieces. If double nickel is placed at the bottom, its corrosion resistance is not lower than chromium. In order to prevent the surface discoloration, the chromate impregnation method improves its corrosion resistance.
Its appearance is light rose, which makes people feel good and has excellent corrosion resistance. Tin nickel alloys can obtain a good bright surface on the bright matrix or bright nickel plating layer. If the matte surface (pear -shaped pattern) is electroplating, the original state of the surface can appear. The uniform electroplating performance of the electrical stealth coating is very excellent, and there is almost no flat effect. It is suitable for electroplating that requires extremely fine lines and rotating processing products.
