Regular size of Nickel alloy wire :
We supply products in the shape of wire,flat wire,strip.We can also make customized material according to useris requests.
Bright and white wire--0.025mm~3mm
Pickling wire:1.8mm~10mm
Oxidized wire:0.6mm~10mm
Flat wire:thickness 0.05mm~1.0mm,width 0.5mm~5.0mm
Process:
Wire:Material preparation→melting→re-melting→forging→hot rolling→heat treatment→surface treatment→drawing(rolling)→finish heat treatment→inspection→package→warehouse
Product features of nichrome wire:
1)Excellent anti-oxidation and mechanical strength at high temperature;
2)High resistivity and low temperature coefficient of resistance;
3)Excellent reelability and forming performance;
4)Excellent welding performace
Application of all grades:
Cr20Ni80:in braking resistors,industrial furnaces,flat irons, ironing machines, water heaters, plastic moulding dies, soldering irons, metal sheathed tubular elements and cartridge elements.
Cr30Ni70:in industrial furnaces. well suited for reducing atmospheres, as it is not subject to 'green rot'.
Cr15Ni60:in braking resistors,industrial furnaces,hot plates, grills, toaster ovens and storage heaters. For suspended coils in air heaters in clothes dryers, fan heaters, hand dryers.
Cr20Ni35:in braking resistors,industrial furnaces.In night-storage heaters, convection heaters, heavy duty rheostats and fan heaters. For heating cables and rope heaters in defrosting and de-icing elements, electric blankets and pads, car seats, baseboard heaters and floorheater.
Cr20Ni30:in solid hot plates, open coil heaters in HVAC systems, night-storage heaters, convection heaters, heavy duty rheostats and fan heaters.For heating cables and rope heaters in defrosting and de-icing elements, electric blankets and pads, car seats, baseboard heaters, floor heaters and resistors.
