1. All copper: the pure copper faucet is refined with all copper and chrome plated on the surface, with high gloss and high wear and corrosion resistance. The quality is mainly distinguished by its own copper content and process. The copper used in the plumbing industry is mainly 59 copper. The number represents the copper content. The higher the copper content, the higher the density and the heavier the weight. Therefore, weight is one of the standards to distinguish the grade of faucet.

2. Alloy: the price of alloy faucet is much lower than that of all copper faucet, and this faucet is easier to produce on a large scale. Zinc alloy is widely used. Zinc alloy faucet is harmful to human body and is not durable. At present, zinc alloy can be used to make faucet handles and some bathroom hardware pendant. Because the zinc alloy electroplating process is very mature, and some manufacturers will deliberately increase the weight of the zinc alloy faucet, it is difficult to distinguish it from the all copper faucet through weight and appearance. For your health, it is still recommended to buy faucets that have passed the evaluation of relevant certification and evaluation institutions.

3. Ceramics: Ceramic faucet is the faucet made of ceramics as the name suggests. Compared with other faucets, ceramic faucets have the advantages of no rust, no oxidation and not easy to wear. The appearance of ceramic faucet is beautiful and generous. Because the shell is also ceramic products, it can be matched with sanitary products to add the artistic sense of ceramic products and set off the high-grade temperament of sanitary ware.

4. Stainless steel: the stainless steel faucet does not contain lead, and is acid and alkali resistant, free from corrosion, does not release harmful substances, and will not pollute the source of water. It is understood that at present, the surface of stainless steel faucets above 304 does not need electroplating. Its surface only needs polishing to show the natural color of stainless steel, and can continuously maintain silver white luster and never rust. The hardness and toughness of stainless steel are more than 2 times higher than those of copper products. However, the hardness, toughness, solution casting and cutting of stainless steel are much more difficult than copper, and the cost is high.
