FeCrAl 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,
metallurgy, machinery, aircraft, automotive, military and other
industries producing heating elements and resistance elements.
