The recommended brands of sinks are Jiumu, Kohler, and Supor. They are cost-effective and safe. Don’t buy other brands you have never heard of. Among them, Jiumu is more recommended.

Currently, copper alloy is the most suitable main material for home use. Because copper ions have a certain bactericidal effect and prevent bacteria from producing antibodies, the inner wall of the copper faucet will not breed bacteria. This is Other materials are incomparable, which is why many brands now choose copper materials to make faucets. Brass among copper alloys is a combination of copper and zinc. It has good mechanical properties, wear resistance and corrosion resistance, so it has become the first choice for faucet materials.

Brass can be divided into many types depending on the copper content. Currently, most faucets are made of H59 copper, which is brass with a copper content of 57% to 61%. In fact, some international bathroom faucets Brands even use H62 copper to produce faucets, because H62 copper has a higher copper content and better corrosion resistance than H59 copper.

In addition to copper and zinc, brass also contains trace amounts (less than 0.5%) of lead. When the faucet was exposed and caused lead poisoning, everyone thought it was caused by the lead in the brass itself, but everyone left Anyone who talks about poisoning at a dose is just a hooligan. The current national standard for lead content in faucets is that as long as the amount of lead released does not exceed 5 μg/L, it will not threaten human health. In fact, standard H59 copper does not need to worry about this problem.

Most of the faucets on the market that have been found to have excessive amounts of lead leaching are not made of standard brass, but are made of shoddy zinc alloy, have too many impurities, or are recycled. It is roughly processed from scrap copper, and the faucets made in this way have quality problems.
