An induction heater is a device that uses an induced electric current to generate heat, and one of the commonly used conductive materials is paper covered aluminum round wire, which is used in the coil windings of induction heaters.

Paper-coated aluminum round wire is a type of wire that consists of an aluminum conductor wrapped in insulating paper. This construction provides good electrical insulation and mechanical protection. Paper-coated aluminum round wire usually has good electrical and thermal conductivity for high-frequency induction heating requirements.

High-frequency induction heaters generate heat energy by generating a high-frequency alternating electromagnetic field in a coil, which produces an induced current in a conductor (e.g., metal) in the workpiece. Paper-coated aluminum round wire is used as the coil winding of the induction heater, and the magnetic field generated by the high-frequency current flowing through the coil can effectively sense and heat the workpiece.

Paper-coated aluminum wire has a number of advantages in induction heaters. First, aluminum has good electrical conductivity and can effectively transfer current and generate heat. Secondly, paper-coated aluminum round wire has lower resistance and self-inductance than other wires (e.g., copper wire), which can reduce current loss and coil self-inductance effect, and improve the efficiency of energy conversion. In addition, paper-coated aluminum round wire is relatively lightweight, easy to wind and install.


Induction heaters are widely used in metalworking, heat treating, welding, melting, thermoplastic processing and other applications. Paper-coated aluminum round wire is used as the coil winding material for induction heaters, which can be used for heating various metal workpieces, melting metal materials, and other applications. Induction heaters provide fast, uniform and efficient heating for workpieces of all shapes and sizes.

When designing, manufacturing and using induction heaters, applicable safety standards and codes need to be followed to ensure the safety of operators and equipment. These standards may cover aspects such as electrical safety, insulation, coil design and construction.

When selecting and using paper clad aluminum round wire for induction heater coil winding, specific application needs, current and voltage requirements, and coil construction need to be considered. Attention should also be paid to the specification and quality of the paper-coated aluminum round wire to ensure that it meets the relevant standards and performance requirements. It is recommended to work with the induction heater manufacturer or a professional engineer for accurate advice and guidance.
