Why do faucets need chrome plating?

When choosing the faucet, I believe many home decoration white people will have this idea: why every faucet is bright?

That's right. Basically, all the faucets, whether they are copper or zinc alloy, are shiny on the surface. People can cast shadows on the mirror. At the beginning, we just think that such faucets should be well looked at.

Later we learned that this is not just for the sake of beauty. This technology is called chrome plating.

Although the name has been widely spread, many people, even those who do not engage in architectural decoration, have heard of the name of chrome plating, but few people know its true connotation and significance.

Chromium is a kind of silvery white metal with a little blue. The chromium plating layer has a high hardness. According to the composition of the bath and the process conditions, the hardness can vary in a wide range of 400-1200hv.

At the same time, the chromium plating layer has good heat resistance. When heated below 500 ℃, its gloss and hardness have no obvious change. The friction coefficient of chromium plating layer is small, especially the dry friction coefficient, which is the lowest among all metals. So the chromium plating layer has good wear resistance.

Similarly, the chromium plating layer has good chemical stability, does not act in alkali, sulfide, nitric acid and most organic acids, and because chromium does not change color, it can maintain its reflection ability for a long time, so it is superior to silver and nickel.

At the same time, there is another important reason for chromium plating on faucets.

Because the faucet needs to be washed by water for a long time, and the main material of the faucet, whether iron or copper, is extremely easy to rust when exposed to air and water for a long time, so it must be plated with a layer of metal that is not easy to rust as protection.

With good chemical stability, corrosion resistance, wear resistance, chromium has become the best choice for this metal.

After finishing his duty of maintaining stability and preventing rust, the faucet designer found that the appearance provided by chrome plating can also add luster to this humble bathroom accessory.

Nowadays, chromium plating has become an indispensable part of all faucets. It is with the development of chromium plating technology that the appearance of faucets has been sublimated and become the shining pearl in the bathroom.
