The difference between chrome plating and galvanizing of metal plating parts

For those who have just contacted the electroplating processing needs, our products need to be galvanized or chrome-plated. It is not very well understood, and galvanized products are often required to be chrome-plated.

So what is the difference between galvanizing and chrome plating?

1. The appearance color is different:

The surface of the galvanized plated parts is a little blue-white, shiny but not very bright. After passivation, it can be made into blue-white zinc, multi-colored zinc, black zinc, military green and other colors.

The chrome finish is bright blue and blue, and the other chrome finishes are black chrome.

2. The function of chrome plating is different from that of galvanized chrome:

Zinc plating is only a layer of zinc metal plated on the surface of the electroplated parts. It is anodized for the iron base and has certain electrochemical protection. The galvanized parts have good rust resistance.

The chrome is plated with decorative chrome and hard chrome. The chrome plating is to plate the surface of the plated part with a single chrome metal layer of several micrometers or more. It has excellent abrasion resistance. The decorative chrome should be plated first. After chrome or nickel plating, the chrome layer is very enamel. It has the function of beauty and protection. It is mainly used for processing products with high decorative requirements.

3. The cost of chrome plating and galvanizing is different

The cost of galvanizing is low, and the cost of chrome plating is high. The cost of chrome plating is higher than that of galvanizing because of the materials used in electroplating, the labor used in electroplating, and the maintenance of electroplating. .
