0Cr25Al5 FeCrAl Alloy Wire Oxidated Golden Colour Resistance/
Heating Wire
General Description
FeCrAl alloy is made by a high-temperature, ferritic
iron-chromium-aluminium alloy which can be used at temperatures up
to 1350 degrees. Typical applications are as electrical heating
elements in high-temperature furnaces in the heat treating,
ceramics, glass, steel, and electronics industries.
Application
Our Products widely apply to chemical industry, metallurgy
mechanism, glass industry, ceramic industry, home appliance area
and so on.
