Zinc

Like tin electroplating, zinc electroplating is often chosen when the cost is a primary concern. One key advantage of plating with zinc is its compatibility with just about any type of metal. Zinc can also produce a wide range of surface colors. In its natural state, zinc will provide a silvery-gray finish, although colors such as blue, yellow and black can be achieved. Important zinc plating benefits include excellent adhesion and its resistance to hydrogen embrittlement. Because of its superior adhesive capabilities, zinc plating is sometimes used to provide a base coat prior to painting. Zinc plating is frequently used in the manufacturing of washers, bolts, nuts, transmission components, armored personnel carriers, and tanks.
