Nichrome Electric Resistance Alloy Wire (Cr20Ni35)
Model No.: Cr20Ni35
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.
