Why do faucets need chromium plating

Why do faucets need chromium plating?

When choosing a faucet, why is every bright ?

That's right. Basically, all the faucets, whether stainless steel or granite, are shiny when they are just bought. People can cast shadows on the mirror. At the beginning, we just thought that this kind of faucet should be well looked at.

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

Although the name has been widely spread, many people even if they do not engage in architectural decoration have heard of the name of chrome plating, but it is not many people who know its true meaning and significance, and even some people say: since the tap can be chrome plated, why can't it be plated with gold?

Chromium is a kind of silver white metal with micro blue color. The chromium coating has high hardness. According to the bath composition and process conditions, the hardness can vary in a wide range of 400-1200 HV.

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

In the same way, the chromium coating has good chemical stability and does not work in alkali, sulfide, nitric acid and most organic acids. Because chromium does not change color, it can maintain its reflection ability for a long time, which is better than silver and nickel.

At the same time, there is another important reason for chrome plating of 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 after long-term exposure to air and water, so it must be coated 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 own job 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, chrome plating has become an indispensable part of all faucets. It is also under the development of chrome plating technology that the shape of faucet has been sublimated and become the shining pearl in bathroom.
