Application

NiCr 70-30 is used for corrosion resistant electric heating elements in industrial furnaces with reducing atmospheres. Nickel Chrome 70/30 is highly resistant to oxidation in air. Not recommend for use in MgO sheathed heating elements, or applications using nitrogen or carburizing atmospheres.

  • Electrical parts and electronic components.
  • Electric heating elements (home & industrial use).
  • Industrial furnaces up to 1250°C.
  • Heating cables, mats and cords.
