Descriptions:
High resistance alloys for electrical heating
FeCrAl heating wire
We can offer heating wire/resistance wire such as NiCr , FeCrAl , CuNi ,CuMn and so on .
They have high electric resistance , good formability and weldability .
It can be sued for making heating element and resistror .
FeCrAl alloys are characterized by excellent oxidation resistance and very good form stability resulting in long element life.
They are typically used in electrical heating elements in industrial furnaces and home appliances.
FeCrAl alloy with high resistivity and service ability temperature than that for NiCr alloy and also has lower price.
The Performance of Fe-Cr-Al Electrothermal Alloys refers to th following table.
Forms: wire, bar, strip,sheet/plate,forging,tube/pipe,etc.
Do you provide free samples?
Yes, we can provide a free sample for testing, If we have sample in stock, The quantity based on the material type, The buyer should bear all the shipping costs.
Please feel free to send us a inquiry and we are looking forward to cooperating with you!
