Resistance Heating Wire
Our resistance heating wire is available in different models which are made of different materials, such as pure nickel, chromel alloy, Fe-Cr-Al alloy and copper nickel alloy. During the production, it was treated by a range of processes like smelting, steel rolling, forging, annealing, drawing, surface treatment, resistance control test, etc. It now has been widely used for making heating equipment like industrial furnace, household heating appliance, various electrical resistors (like locomotive braking resistor), and so on.
