Nickel Products

Purpose:

Nickel Chromium Alloys Filament wire

Variety specifications and detailed parameters:

Resistance Alloy Wires is used for electrical heating element. 

Nickel chromium alloy with iron resistance electrothermal high resistivity, surface body sexual well. At high temperature and high intensity, 

and a good performance and processing may welding nature widely used metallurgical, electrical, mechanical components and electrical 

manufacturing industries for doing heat resistance material. 

NiCr Type:Cr20Ni80,Cr30Ni70;Cr15Ni60, Cr20Ni35, Cr20Ni30, Cr25Ni20 etc.Series electric flat belt, electric fire wire.

 

FeCrAl Electrictrical Resistance Heating alloys with high electrical resistivity, temperature coefficient of resistance is small, high operating

 temperature. good corrosion resistance under high temperature, and particularly suitable for use in a gas containing sulfur and sulfides, low price,

 FeCrAl type:1Cr13AI4, 0Cr21AI4, 0Cr21AI6, 0Cr25AI5, 0Cr21AI6 Nb, 0Cr27AI7Mo2 etc.Series electric flat belt, electric fire wire
