Product Description
Hotsale Factory Price Ni80Cr20 Electric Nichrome Nikr0thal 80 Heating Resistance Wire
Ni80Cr20 Ribbon: Width 5~0.5mm, thickness 0.01-2mm
Grade: Ni80Cr20, Ni70Cr30, Ni60Cr16, Ni60Cr23, Ni35Cr20Fe
Nichrome's metallurgical structure confers them a very good plasticity when cold.
In addition of a relatively high specific resistance, Ni-Cr alloys join all the necessary properties for good performances in use of furnaces: Resistance to oxidation (they are not sensitive to aggressions of humid air).
Low embrittlement at high temperature. Good plasticity-Easier to give them a shape compared with FeCrAl (lower mechanical characteristics allow indeed a good control of elasticity of the product during shaping (coiling, folding, drawing).
Good resistance to creeping (more important than ferritic alloys) which is important during conception of a resistance presenting big heights of waves.
