304 stainless steel advantages are very good, but the shortcomings are also very obvious, processing difficulties, used for plumbing and sanitary ware do not fit in, a little less attention to injury to the main pieces, and high cost, difficult to operate, plumbers and electricians are easy to get tight not loose, and in the north does not keep warm there is also the risk of burst pipe.
And copper faucet has been the European side of the centuries-old tradition, our own sanitary brand is not very strong, high-end basic in Europe and the United States side, so we can only go with others.
Another is that although copper in some aspects than stainless steel, but compared to cast iron, zinc alloy is still much better.
And although copper is easy to long patina, but the patina is also a protective layer, can prevent further corrosion, you see archaeological digging out of the metal is only gold, silver and copper, buried thousands of years are fine, other iron and other metals are rotten.
