Delivery forms - Kanthal®, Alkrothal® and Nikrothal®

To prevent transport damage, all goods are securely packed in either cardboard boxes or wooden cases, with appropriate internal protection. Resistance heating alloys are available in a variety of delivery forms, including wire spools, pails, coils, and strips, to cater to diverse

Standard tolerances

Standard tolerances for wire are provided 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 mm (0.005

Tubothal®

TUBOTHAL® – THE MOST POWERFUL METALLIC ELEMENT SYSTEM Tubothal® is an ideal electric element used in combination with powder metallurgy tubes because of its great advantages, such as – very high power – long life – low weight – easy to design to existing power controls and supply. Combined

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

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

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

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
