Electronic Nichrome Alloy Heating Bright Wires
Introduction of heating wire:
The Nichrome chemical composition is nickel, chromium and ferrum, it used at operating temperatures up to 1200 degrees. Its chemical composition gives good oxidation resistance, especially under conditions of frequent switching or wide temperature fluctuations. They are used for electric resistances of appliances or for application of industrial furances.
1 good oxidation resistance
2 low embrittlement at high temperature
3 good plasticity(easier to give them a shape)
4 nice performance and processing
Applications of heating wire:
1 used in the explosives and fireworks industry as a bridgewire in electric ignition system
2 Industrial and hobby hot wire foam cutters
3 testing the colour of the flame in the non-luminous part of fire of a cation
4 used in ceramics as an internal support structure
