 Application:

Over a long period of time, our products (Fe-Cr-Al/Ni-Cr) high resistance and heating alloy materials are salable and widely used in various industries, such as metallurgical, chemical, glass, ceramic, and electrics for instance, they can be used for industrial and civil heating-furnace, infrared equipment, liquefied gas infrared heat-resisting net, different kinds of igniting and radiating electrodes and voltage-regulating resistors for motors and so on.
