The main material of kitchen faucets currently used in China is brass HPb59, which contains trace amounts of lead.
The main components of steel are iron and carbon. Ordinary carbon steel is easy to oxidize and rust. Adding chromium, nickel, and other metals to carbon steel can make the steel have a corrosion-resistant passive film, which prevents the metal from being further corroded. , so as not to rust. An important factor affecting the corrosion resistance of stainless steel is the content of chromium elements. The higher the chromium content, the less likely it is to rust.
Stainless steel faucets are safe and lead-free, free of corrosion and exudates, and have no odor or cloudiness issues. It will not cause secondary pollution to the water quality, keep the water quality pure and hygienic, and fully guarantee hygiene and safety. The melting point of stainless steel is higher than that of copper, and it is not easy to form. At present, the production process is relatively immature. The faucet needs to be replaced every 3 to 5 years, and 6 new faucets need to be purchased in less than 30 years, and the overall cost is higher. The market and technology are relatively mature, and mass-produced copper faucets can meet the needs of consumers at different levels.
