1.Introduction to products
Fe-Cr-Al alloy
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.
