Faucets, angle valves, showers, this kind of household water-related hardware, always claim to be all copper. But is all copper really good? This is not necessarily true. At least copper can never avoid rust in use!

In order to prevent rust, copper will make some improvements in the material-made of copper-zinc alloy or copper-lead alloy (so all copper ≠ pure copper). If so, its corrosion resistance is still difficult to meet the demand. So we have to make some articles on the surface-electroplating process.

The so-called "copper" faucets and other hardware we usually see are all copper that has been alloyed and electroplated.

Better than copper is stainless steel. This thing is quite resistant to corrosion, "not rusting" is just its basic ability. And the hardness is high, relatively speaking, the life span is longer.

The reason why it is difficult to see stainless steel in water fittings is mainly because its hardness is too high-when processing high-precision products such as faucets, high hardness means high difficulty. Therefore, stainless steel hardware is not absent, but the price is too high and the cost performance is too low.

Overall, copper hardware is not the best, but it is the most cost-effective. For home users, copper hardware has been able to meet the demand.
