Specification

High quality Low Price FeCrAl Alloy Wire

Fe-Cr-Al alloy has the characteristic of high resistivity,low temperature resistance coefficient,high operating temperature,good anti-oxidation and anti-corrosion under high temperature.

It is widely used in industrial furnace, household appliances, industry furnace, metallurgy, machinery, aircraft, automotive, military and other industries producing heating elements and resistance elements.

nichrome heating alloy includes pure nickel, NiCr alloy, Fe-Cr-Al alloy and copper nickel alloy.

FeCrAl resistance wire grade: 0Cr25Al5, 1Cr13Al4, 0Cr23Al5, 0Cr27Al7Mo2, 0Cr21Al6Nb, 0Cr21Al4, 0Cr21Al6.

In the form of wire, ribbon and strip, one kind of material Fe-Cr-Al alloy.

Wire: 0.018mm-10mm

Rod: 8mm-50mm

Ribbon: 0.05*0.2mm-2.0*6.0mm
Strip: 0.5*5.0mm-5.0*250mm
