FeCrAl Kanthal A-1 Resistance Wire Mesh is a FeCrAl alloy that consists of high resistivity and tremendous resistance to oxidation. It is widely utilized in the commercial applications that are conducted at the temperatures about 1400oC. Due to high resistivity coefficient, it offers large resistance to electricity at the high temperature so produce enormous heat. It fits best for the production of heating equipments such as commercial furnace terminals, air heating materials and others.
FeCrAl Kanthal A-1 Resistance Wire Mesh comprises of large tensile strength and yield strength. It is used in making ceramics, and electronic parts.
