Electric heating wire is a kind of functional alloy material that converts electric energy into heat energy. Its maximum working temperature is over 1 thousand degrees Celsius, and it is used to manufacture various electric heating elements in the fields of metallurgy, construction, military industry and home appliances. The electric heating tube is divided into three categories: stainless steel electric heating tube, carbon fiber heating tube and ceramic electric heating tube. It is an electric heating element that is electrically heated and non-conductive, and has higher safety. It can be applied to more than 80% heating equipment.
