NW-HTP is a FeCrAl alloy with high resistivity suitable for use at temperatures up to 1400°C. It is developed by us to supply our domestic clients as a substitute of Kanthal A-1 wires, It has high oxidation resistance, and mainly used to making many types of heating elements used for home appliances as well as in industrial applications.
