Product description
Nickel Chrome wire has the organizational stability of such heating alloy, electrical stability of physical properties,high temperature and good mechanical properties, weldability is good, long-term use will not produce brittlefracture. Used for manufacture of household appliances and working temperature below 1000 ℃ heating element, longlife. Because of high nickel content, so the price is higher.
