Nichrome 20/25 Resistance Heating Wire
Nichrome Ni20Cr25 resistance heating wire is nickel-chromium-iron resistance alloy with heat resisting strength at high temperatures. Its properties is much similar with nichrome 30/20.This alloy is also used in numerous domestic appliances and industrial resistors.
Nichrome 20/25 Wire has relatively high resistivity and very good resistance to oxidation at high temperatures. Nichrome 20/25 Wire is used in industrial furnaces (up to 1050°C), heating elements of cooking equipment.
To ensure the quality of our product, we can produce the product with raw materials from the international suppliers. Every batch of product can be tracked to the original raw material supplier. We co-operate with international suppliers like Allvac(ATI), Bohler, Carpenter, Dunkirk, Gloria, OttoKumpu, SMC, ThyssenKrupp VDM, Valbruna, etc.

Nichrome 20/25 wire 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.
