Operating life and maximum permissible temperature

When heated, resistance heating alloys form an oxide layer on their surface, which prevents further oxidation of the material. To accomplish this function the oxide layer must be dense and resist the diffusion of gasses. It must also be thin and adhere to the metal under temperature

Element surface load

Since Kanthal® alloys can be operated at higher temperatures than Nikrothal® alloys, a higher surface load can be accepted without jeopardizing element life. Element design is also of great importance. The more freely radiating the element form, the higher the maximum surface load can

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

Stranded resistance heating wire

Recognizing the need for more precisely controlled stranded wire within the heat treatment industry and working closely with our cable customers, Kanthal has developed a range of stranded resistance wires in the well known Nikrothal®, Kanthal® and nickel alloys. Content: Strand diameter

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

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

Austenitic alloys

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,

Ferritic alloys

FERRITIC (FeCrAl) ALLOYS Ferritic, iron-chrome-aluminum (FeCrAl) alloys have high electrical resistivity and are highly resistant to high-temperature oxidation. These are ideal qualities for electric heating elements and resistance materials in electronic equipment. Our product range of FeCrAl
