For millennia, alloys have helped human in expanding construction capacity and act as the cornerstone for innovation, among which, brass and stainless steel are the two biggest categories to be widely applied in construction, transportation, machine building, and plumbing.
Brass is an alloy of copper and zinc, and it is favored by people for its superior corrosion resistance, thermal conductivity,and easy processing properties. But everything has two sides, it used to be a common practice to add lead to brass for better malleability. But if such brass contains high level of lead, is used in fixture contacting with food and drinking water, when lead together with food and water gets into body and be absorbed and stored in our bones, blood, and tissues, it can cause chronic lead poisoning and affect body system by damage to hematopoietic system, nervous system, digestive system, cardiovascular and cerebrovascular system and kidney.
More and more countries and regions starts to attach importance to dangers of lead, and implement new regulations to limit use of lead.
Quality stainless steel is an alternative material to the lead free regulations, as it is 100% lead-free, safe to use and in accordance with NSF372. 304 and 316 stainless contain 18% chromium and 8-10% nickel, the nickel gives the steel a particular crystalline structure to increase the material’s strength and malleability while the chromium helps the steel resist corrosion, which is good enough for some plumbing fixture such as taps. That’s also why from the initial beginning, Flowtech choose 304 or 316 stainless steel for our Xpressfit tap series, though it requires higher design & processing capabilities，it is healthy to use and benefit users and environment.
