Kranar materialklassificering
The faucets commonly used in the market today are stainless steel, mässing, zinc alloy faucets.
1.Mässing: kitchen and bathroom products made of Brass have become popular to all over the world. Den är gjord av internationell standard H59/H62 koppar. The casting is made by steel die for gravity casting. Its wall thickness is uniform, i allmänhet 2.5-3.0 mm.
advantage:The faucet made of brass is characterized by: ingen rost, hållbar, antioxidation, bactericidal effect on water
disadvantages: lead is a kind of metal that is harmful to health, international standards require that lead in copper content should not exceed 2.5%.
2.Rostfritt stål: Entering the 21st century, health and environmental protection have gradually become a new theme in modern life. Rostfritt stål är ett internationellt erkänt hälsosamt material som kan implanteras i människokroppen.
advantage: health, miljöskydd; all materials are made of high quality 304 rostfritt stål, ingen rost, no lead, the faucet itself will not cause secondary lead pollution to the water source, harming people’s health, can create a healthy kitchen for us. Hygienic living water environment.
disadvantage:på grund av den höga hårdheten och segheten hos rostfritt stål, det är svårt att tillverka och bearbeta, vilket allvarligt påverkar massproduktionen av rostfria kranar. Därför, priset på verkliga 304 stainless steel faucets is higher than that of copper.
3.Zinklegering: low-grade material, the density of zinc alloy is smaller than that of copper, and the tap of the copper material is not heavy. From the inner wall, the surface of the zinc alloy is easily oxidized, and white oxidized powder appears on the surface.
Styrkan är mycket sämre än koppar, the service life is not long, och blyhalten är hög. If the faucet made of zinc alloy is only one to two years, det kommer att oxidera och ruttna.
Numera, zinc alloy is mainly used for the manufacture of faucets. It is die-casted from zinc alloy and then chrome-plated. Most of the faucet handles on the market are zinc alloy.
