Description of Iron Chrome Aluminum Heating Wire
This Iron Chrome Aluminum Heating Wire is known to have higher surface loading capability, higher resistivity, and lower density than Nickel Chrome (NiCr) alternatives which can translate to less material in the application and weight savings. It has superior antioxidant anti-carburizing of sulfur and has a lightweight, high surface load, long service life, and low price. It has been widely used in industrial furnaces, metallurgy, machinery, household applications, and other industries producing heating elements and resistance elements.
