Compared with copper, stainless steel faucet has high hardness and toughness. Stainless steel faucets are durable, hygienic and environmentally friendly, and are beneficial to human health. Moreover, it is resistant to acid and alkali, is not corroded, and does not release harmful substances.
Due to the strong hardness of stainless steel, the precision casting process is much more complicated than that of copper, the consumables are very expensive, and the sealing performance is not good, so the price is also relatively expensive.
Although stainless steel does not rust, if you buy inferior goods from bad merchants, there will still be some rust in the later period of use. Moreover, stainless steel is an emerging industry, and a variety of toxic heavy metals will inevitably be added to the production process. Although there is no data to indicate whether these heavy metals will be precipitated in water for a long time, some people want to reduce costs, so they cannot guarantee real stainless steel production.
The chemical properties of brass shower faucets are more stable than those of stainless steel, acid and alkali resistance, long service life and durability. The texture of copper is relatively soft, the melting point is low, the plasticity is strong, the production process is mature, the cost is controllable, and it is conducive to circulation.
High-quality copper can kill 99% of the bacteria in tap water, so there is no need to worry about overnight water, or the foreign matter entering the infected bacteria caused by the burst of tap water.
However, copper faucets contain metal lead and patina to varying degrees, and copper with poor material will contain more metal lead.
