Materials for hardware
Hardware is an inseparable part of people's lives every day to see the hardware shadow. Hardware is usually used metal materials . Hardware can be divided according to the type of metal , gold, silver , copper , iron, tin and other five metals.1 , brass , brass is an alloy of copper and zinc , the color increases with zinc content . Mechanical properties than copper brass high , under normal circumstances does not rust and will not corrode , and plasticity better able to withstand hot and cold processing.
2 , bronze, refers to an alloy of copper and tin , accustomed to other copper alloys brass and copper-nickel alloy called bronze outside the industry .
3 , phosphor bronze, bronze containing phosphorus component becomes phosphor bronze.
4, stainless steel , stainless steel, acid-resistant stainless steel is short . In the atmosphere, water vapor , fresh water and other weak corrosive medium or corrosion of stainless steels have called stainless steel, acid and just generally have a stainless steel.
5 , aluminum , aluminum alloys based on aluminum general. Alloying element intensity is relatively high, close to or exceed the high quality steel , good plasticity , can be processed into a variety of profiles, with excellent electrical conductivity, thermal conductivity and corrosion resistance , widely applied in industry , second only to the use of steel .
