• Ni80Cr20 Details

  
  
  

  Cr20Ni80 is a resistance electric heating alloy with stable microstructure, stable electrical and physical properties, good high-temperature mechanical properties, good cold deformation plasticity, good weldability, and no brittle fracture after long-term use. Mainly used for manufacturing household appliances and heating elements with working temperatures below 1000 ℃, with a long service life. Due to its high nickel content, the price is relatively high.
