Aluminum Magnet Wire refers to the magnet wire with aluminum as the core, which is used to make insulated wires for coils or windings in electrical products. Also called winding wire. It is necessary for magnet wire to meet the requirements of various applications and manufacturing processes. The former includes its shape, specification, ability to work at high temperature for a short time and a long time, as well as acceptance of intense oscillation in some occasions and centrifugal force at high speed, resistance to corona and breakdown under high voltage, resistance to chemical corrosion under special atmosphere, etc. The latter includes the requirements of stretching, twisting and abrasion during winding and embedding, swelling and erosion during dipping and drying.

Aluminum magnet wire can be classified according to their basic composition, conductive wire core and electrically insulating layer. Generally, it is divided into aluminum core enameled wire, aluminum core wrapped wire, aluminum core enameled wrapped wire and inorganic insulated wire according to the insulation material and manufacturing method used for the electrical insulation layer.

The aluminum magnet wire is prepared by coating the conductor with corresponding paint solution, evaporating the solvent, curing the paint film, and cooling. The enameled wire can be divided into polyester enameled wire, polyester imide enameled wire, polyamide-imide enameled wire, polyimide enameled wire, polyester imide/polyamide-imide enameled wire, corona resistant enameled wire, oily paint, acetal paint, polyester enameled wire, etc. according to the insulation paint used. Sometimes it is also classified according to the particularity of its use, such as self-adhesive enameled wire, cryogen-resistant enameled wire, etc.

Inorganic insulation wire for aluminum electromagnetic wire: when the heat resistance level exceeds the limit of organic materials, inorganic insulation paint is generally selected for coating. Existing inorganic insulation wires can be further divided into glass film wires, oxide film wires, ceramic wires, etc.

Because the use of aluminum electromagnetic wire is increasingly widespread and the requirements are increasingly strict, composite enameled wires have also been developed. The inner and outer paint films are made of different polymer materials, such as polyesterimide/polyamideimide enameled wire. Therefore, aluminum magnet wires are increasingly used in various related professions, and the industrial position of aluminum magnet wires cannot be replaced.
