How to choose the materials of faucets?
Faucets are closely related items in our lives. Most people should have had the experience of buying faucets. We can often hear that the price of full copper faucet is 25 RMB, a zinc alloy one is 10 RMB, SS304 faucet one is 160 RMB. From a few to a few hundred RMB, are you confused? Today, I will let you the materials of faucets and why their prices is so big difference. You will have a better understanding of how to choose the material of faucet.
Faucet material classification: The common faucet materials on the market today are: stainless steel 304, all plastic, brass, zinc alloy material faucet and other categories.
1. Brass: Brass is the most common material for faucet manufacturing. It is made of H59/H62 copper, which is an international standard. The casting adopts a steel mold for gravity casting. Its wall thickness is uniform, generally 2.5-3.0 mm. The characteristics of the faucet made of brass are: non-rust, durable, anti-oxidation, and sterilization effect on water (the disadvantage is: contains lead, lead is a harmful metal, international standards require that the lead in copper content should not exceed 2.5%.
2. Zinc alloy: low-grade material, the density of zinc alloy is lower than that of copper, and the tap without copper feels heavier. From the inner wall, the surface of zinc alloy is easy to oxidize, and white oxide powder will appear on the surface. The strength is much worse than copper, the service life is not long, the lead content is high, if the faucet made of zinc alloy will oxidize and rot in only one to two years. Now zinc alloys are mainly used to make handles for faucets. It is made of zinc alloy die-casting and then chrome plated. Most faucet handles on the market are made of zinc alloy.
3. Engineering plastics: ABS plastic faucet has the characteristics of corrosion resistance, aging resistance, no rust, no lead, no poison, no taste, high pressure resistance, light weight, simple construction, low price, etc. It is a new type of green environmental protection product The water quality is free from the risk of rust and pollution; the faucet made of plastic is environmentally friendly, non-toxic, non-polluting, compact in shape, simple and convenient to install, and meets the national drinking and civil drinking water standards.
4. Stainless steel 304: In 21st century, health and environmental protection have gradually become the new theme of modern life. Stainless steel 304 is an internationally recognized healthy material that can be implanted into the human body. Therefore, kitchen and bathroom supplies with stainless steel 304 as the main material have begun to become popular in European and American countries. However, due to the high hardness and toughness of stainless steel, it is difficult to manufacture and process, which seriously affects the mass production of stainless steel faucets. Therefore, the price of real 304 stainless steel faucets is higher than the price of copper. Its characteristics are: health and environmental protection; the product materials are all made of high-quality 304 stainless steel, which is not rusty and lead-free. The faucet itself will not cause secondary lead pollution to the water source, harming people's health, and can create a healthy kitchen and water environment for us.
