| 304 stainless steel angle valve, multiple advantages, including the use of 50 years!A beautiful,Copper surface the best processing method are plating nickel and chromium. Fast a year, generally 3-5 years, slow person 10 years gradually lost its surface gloss, pitting, finally plating peeling, revealing patina. And polished stainless steel angle valve surface will always remain a silver-white luster, never rust, after many years of use as long as you wash wipe it clean water, clean and bright, luxurious new.Two, durableStainless steel hardness, toughness of 3 times more than copper. Never, never rust and corrosion, frost resistance. Brass angle valve often encounter the thread breaks in embedded nut, or due to rust and corrosion and rupture caused by water leakage, and these will smash tiles to replace, very trouble. Stainless steel angle valve into a lifelong enjoyment, but also from the middle of the replacement of the angle valve trouble.Three, health, environmental protection, no leadStainless steel does not contain lead, and acid and alkali resistance, corrosion resistance, does not release harmful substances, does not pollute your source, to ensure human health, hygiene, environmental protection. Very suitable for direct drinking water. Copper faucet leaded and release the lead element, lead is harmful to human body, it will generate copper oxide, causing the patina, contamination of your water, health risk. Now, the children are not even exceed the standard blood lead high blood lead, causing anemia children and even mental decline, how to reduce childhood lead ingestion is the young parents must consider the problem.Four, complicated manufacturing process, high processing difficulty high costStainless steel copper melting point melting point of about 1600 degrees, about 1000 degrees; the hardness and toughness of copper stainless steel is more than three times, machine tool loss rate is a hundred times more copper; stainless steel polishing material wastage rate is more than 10 times of stainless steel cop |
