China Top Manufacturer Nichrome Wire

Nichrome alloys are in the form of wire and strip for use at 1100℃~1250℃(2010°F~2280°F).It is supplied with bright and oxidized surface,spooled and coiled package.They are mainly used in industrial furnace and various heaters,resistors.    

The advantages:

Have higher hot and creep strength than FeCrAl alloys.

Better ductility after long use than FeCrAl alloys.

Generally have better corrosion resistance at room temperature than FeCrAl alloys.

Longer life span than FeCrAl.

Our Nichrome products are mailly included Ni80Cr20,Ni70Cr30,Ni60Cr15,Ni35Cr20,Ni30Cr20.
