Model NO.: Cr20Ni35 Material: Nicr Size Range Wire: 0.018-10mm Size Range Strip: 0.05-5*5-250mm Treatment: Hydrogen Annealing Application: Heater,Furnace,Boiler,Oven Trademark: XL Origin: China Product Type: Wire Carbon Content: Low Carbon Size Range Ribbon: 0.05-0.2*2-6mm Shape: Wire,Ribbon,Strip,Bar,Sheet Surface: Oxidized,Bright. Chemical Composition: Nicr Specification: demension customzied HS Code: 75052200 Nichrome 35/20 Alloy has excellent resistance to high temperature oxidation and corrosion and good wear resistance. Nichrome 35/20 Resistance Heating Wire
has good deformation ability, thermal stability, mechanical character, shockproof ability in thermal state and anti-oxidization.
Nichrome 35/20 is widely used in conveyor belts for industrial furnaces.
Applications: 1.Heating Elements Manufacturers mainly use nichrome wire to make coils for heating elements. 2.Hot-Wire Cutter It cuts through materials like polystyrene foam, somewhat like a wire cheese cutter. The heat does the cutting, and makes a smoother and more even cut than a saw or knife could achieve. 3.High-Temperatures Uses Because of nichrome wire's strength at extremely high temperatures and its flexibility, pottery enthusiasts use it to assemble backyard kilns and to hold the shape of pottery items while they bake. 4.Igniters Nichrome Wire heats up rapidly with even a small amount of electricity; it makes safe igniters (sometimes called electric matches) to light the fuses of fireworks and model rockets.
