Copper Nickel Wire manufacturer in India

Types of Copper Nickel Wire

  • Hecnum (CuNi44) - Hecnum (a registered Trademark of Omega Resistance Wire) or CuNi44 is a Copper Nickel alloy containing Nickel, Manganese and balance Copper. It is suitable for low temperature heating elements up to a maximum of 400 °C.
  • Copper Nickel 23 wire- Copper Nickel 23 or CuNi23Mn is a copper nickel alloy with the addition of Manganese to produce an alloy with a relatively low resistivity but high resistance to oxidation and chemical corrosion. Maximum working temperature is 500 °C.
  • Copper Nickel 6 wire - Copper Nickel 6 or Alloy 60 is characterised by low resistivity, with a medium resistance to oxidation and chemical corrosion. The maximum working temperature is 300 °C.
