Today, with the development of economy and science, there are various faucets with cast iron, all plastic, all copper, alloy, ceramics, stainless steel and other materials as the main body. Among them, cast iron faucets have been gradually eliminated, and all-plastic faucets are mostly used in special fields. At present, the faucets that are most frequently contacted in the family mainly include all copper, alloy, ceramic and stainless steel faucets. Alloy faucet has been out of people's sight more and more because it is harmful to health. Although ceramic and stainless steel faucets have their own advantages, they are generally expensive and difficult to process, so there are fewer types and quantities of products. All-copper faucet occupies a dominant position in the leading material market with its excellent cost performance.

? I. All-copper faucet

Pure copper faucet is made of pure copper, with chrome-plated surface, high gloss, wear resistance and corrosion resistance. Quality is mainly distinguished by its own copper content and process. Copper used in plumbing industry is mainly 59 copper. Besides copper, there are other metals. If the lead content is too high, it will be harmful to human health. At present, the lead content of many faucets on the market is generally 3%-5%. In view of this situation, some manufacturers have been developing low-lead faucets, the lead content of which can be lower than 0.3%. In view of the fact that it is difficult for ordinary consumers to judge the lead content, and there are strict regulations on the lead content of pipeline products in the world, it is best to buy faucets that have passed relevant certification for their own health. (Tip: When you get up every morning, you can turn on the tap for half a minute to drain the water inside to avoid taking too much lead. )

? Second, the alloy faucet

? Compared with all-copper faucets, the price of alloy faucets is much lower, and this kind of faucets is easier to produce on a large scale. Among them, a large number of zinc alloys are used, and zinc alloy faucets are harmful to human body and not durable. At present, zinc alloy can be used as the handle of faucet and some bathroom hardware pendants. 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 in terms of weight and appearance. For your health, it is still recommended to buy faucets that have passed the evaluation of relevant certification and evaluation institutions.

? Third, ceramic faucets Ceramic faucets, as the name suggests, are faucets made of ceramics. Compared with other faucets, ceramic faucets have the advantages of no rust, no oxidation and no wear. Ceramic faucets are beautiful and generous in appearance, because the shell is also ceramic products, so they can be matched with bathroom products to add the artistic sense of ceramic products and set off the high-grade temperament of bathroom.
