Brass is the most common material for the manufacture of brass bath faucets. It is processed from international standard H59/H62 copper. The casting adopts steel mold for gravity casting, and its wall thickness is uniform, generally 2.5-3.0 mm. The faucet made of brass is characterized by no rust, durability, anti-oxidation, and bactericidal effect on water. The disadvantage is that it contains lead. Lead is a metal that is harmful to health, and international standards require that the lead content in copper should not exceed 2.5%.
Entering the 21st century, health and environmental protection have gradually become the new themes of modern life. Stainless steel is an internationally recognized healthy material that can be implanted into the human body. Therefore, kitchen and bathroom products mainly made of stainless steel have become popular in Europe and the United States. But the price of real 304 stainless steel faucet is higher than that of copper.
Zinc alloy is a low-grade material. The density of zinc alloy is smaller than that of copper, and the faucet that feels less than copper is heavier. The surface of zinc alloy is easily oxidized from the inner wall, and white oxidized powder will appear on the surface. The strength is much worse than copper, the service life is not long, and the lead content is high. If the faucet made of zinc alloy is only one to two years old, it will oxidize and rot. Now zinc alloy is mainly used to make the handle of the faucet.
