Connaissance des matériaux chauffants

Ferritic alloys (FeCrAl)

These alloys have high electrical resistivity and are highly resistant to oxidation

Austenitic alloys (NiCr, NiCrFe)

These alloys have high mechanical strength, even at high temperatures

Kanthal® or Nikrothal® for industrial furnaces?

The two main types of alloys have their own specific properties

Nickel-iron alloys (NiFe)

These alloys have low resistivity and high temperature coefficient of resistance

Copper-nickel alloys

Versatile alloys with a special characteristics – both electrical and mechanical

Stranded resistance heating wire

Stranded resistance wires in the well known Nikrothal® and Kanthal® alloys

General factors and furnace-specific factors

Element life is dependent on the alloy used, element temperature, element design

Furnace-specific factors

When heated, resistance alloys form an oxide layer on their surface preventing further oxidation
