1. Cast iron faucets belong to old-fashioned faucets, and due to the easy rusting of cast iron, they are usually painted externally to prevent rust. This type of faucet is relatively rough in manufacturing, prone to polluting water quality, prone to rusting and leakage of valve bodies, and has been basically eliminated.
2. Plastic faucets are generally made entirely of PVC material, with rich colors, and can be mass-produced using molds. Plastic faucets have the characteristics of low price, corrosion resistance, light weight, high pressure resistance, and are rust free and non-toxic. However, plastic faucets are not sturdy, have a short lifespan, and are prone to producing a loud whistling sound when draining water, which is very disturbing to the public.
3. Alloy faucets are similar to plastic faucets, with low prices and easy mass production. Alloy faucets are mostly made using sandblasting technology and machine die-casting. The biggest disadvantage is that they are prone to sand holes inside, have poor toughness, and often experience cracking during use in China.
4. Due to its antibacterial and bacteriostatic properties, copper is suitable as a material for faucets. Moreover, all copper faucets are excellent in terms of corrosion resistance, acid and alkali resistance, and wear resistance, making them the best material for faucets. However, currently most faucets on the market are made of alloy copper, which is pure copper or 59 copper. Some products contain a small amount of lead, which is harmful to the human body.
5. The biggest advantage of stainless steel faucets is that they do not contain lead, and like all copper materials, they have better acid and alkali resistance, corrosion resistance, hardness, and toughness than pure copper. However, the processing difficulty of stainless steel products is relatively high, the technology is not yet mature, and the cost is relatively high.
6. Ceramic faucets have high aesthetic value, are rust resistant, wear-resistant, and do not pollute water sources. Ceramic faucets are highly artistic and can be integrated into kitchen and bathroom design effects. However, the high price and fragility of ceramic products are also the biggest drawbacks
