Relevance

Nichrome is a group of alloys based on nickel and chromium with silicon, manganese and iron additives. Due to the high resistance, nichrome is relevant for the manufacture of heating elements for household equipment and industrial grill ovens. It is designed for operating temperatures of the order of 1100 - 1200 °C. The considerable nickel content gives the alloy the ability to dissolve other metals without loss of ductility and corrosion resistance in hot liquid and gaseous media. Chromium enhances the heat, hardness and corrosion resistance of nickel alloys. Nichrome is known for its combination of high strength, heat resistance and ductility. The negligible coefficient of thermal creep allows the production of minimum diameter wire slightly thicker than a human hair. Nichrome strip can be as thick as 0.1 mm with a width of 6 - 250 mm.

Advantages of

Nichrome has a successful combination of heat resistance and high electrical resistance. The minimum coefficient of thermal expansion allows the wire not to sag at significant temperatures. The surface oxides of chromium and nickel give the alloy excellent corrosion resistance which allows it to be used in aggressive environments. It has good processability. Its plasticity allows the finest wire and strip to be rolled in a cold condition. Heat resistance helps nickel alloy fragments withstand mechanical stresses without deformation or fracture.

Féchral

Féchral is also used in the production of heating elements for household equipment and industrial firing furnaces, but because it lacks nickel, it is cheaper and therefore more attractive to the customer. The alloy consists of up to 15% chromium, up to 5.5% aluminum, about 1% silicon and manganese each. The rest is iron. It is a hard and rather brittle alloy, which is difficult to process. Electrical resistance is 1.2-1.3 Ohmxmm²/m - one of the highest among metals. Specific weight (7.1 - 7.3 kg/m³) depends on the percentage of elements in the composition. The maximum operating temperature is ≤1400°C.

X23YU5T.

This is an alloy based on iron, chromium and aluminium. The alloy consists of almost a quarter of chromium, but only 0.6% of the costly nickel. The small amount of nickel makes fahl cheaper and more attractive to the consumer. The ultimate operating temperature is 1≤400°C. The wire production is regulated by GOST 12 766.1-90. As the wire diameter increases the limiting operating temperature increases.

Application

Production of electric heating elements for industrial furnaces as well as starting and braking resistors for rolling stock. Alloy Kh27Yu5T is relevant for heating elements of industrial and muffle furnaces with the limiting temperature of ≤1350°C. Alloy X23Yu5T today displaces from this sector such grades as X15Yu5 and X27Yu5T. At the same price X23Yu5T surpasses its analogues in performance characteristics.
