Nickel-iron alloys

NICKEL-IRON (NiFe) ALLOYS Nickel-iron (NiFe) alloys for up to 600°C (1110°F): Nifethal® 70 and Nifethal® 52 are alloys with low resistivity and high temperature coefficient of resistance. The positive temperature coefficient allows heating elements to reduce power as temperature

Austenitic alloys

AUSTENITIC (NiCr, NiCrFe) ALLOYS Nickel-chrome (NiCr), also called nichrome, alloys have a high mechanical strength, which is retained even at high temperatures. This makes them suitable as heat-resistant material in industrial processes. Kanthal’s NiCr alloy products, Nikrothal®, are also

Embedded element type

Content: Coils in grooved metal plates Cartridge elements, powder filled Heating cables and rope heaters Mica elements The wire in the embedded element type is completely surrounded by solid or granular insulating material. Metal sheathed tubular elements Kanthal® D is generally the best

Standard tolerances

Standard tolerances for wire and ribbon are given below. Size tolerances do not apply to material manufactured to resistance tolerances and vice-versa. Tolerances on electrical resistance RESISTANCE OF WIRE AT 20°C (68°F) Diameter ≤ 0.127 mm (0.005 in) ± 8%. All dimensions > 0.127

Design factors

Content: Operating life Oxidation properties Corrosion resistance Maximum wire temperatures as a function of wire diameter when operating in air Operating Life The life of the resistance heating alloy is dependent on a number of factors, among them the most important are: temperature

Copper-nickel alloys

COPPER-NICKEL (CuNi) ALLOYS Copper-nickel (CuNi) alloy Cuprothal® 49 (universally known as Constantan) is manufactured under controlled conditions from electrolytic copper and pure nickel. Cuprothal® 49 has a number of special characteristics – some electrical, some mechanical – which
