Current Position : HOME/Magnet Wire/ High-Quality aluminum magnet wire

The aluminium enameled wire industry is a basic material industry supporting electrical appliances, home appliances and electronic information, communications and other industries. Its direct users are product manufacturers in these industries.

Its market demand develops with the requirements of these industries. And manufacturing technology improves with the continuous emergence of new technologies in these industries.

What is the Enameled Aluminum magnet wire?

enamelled aluminum wire belongs to a variety of aluminum magnet wire, which refers to the round or flat conductor drawn by the electric round aluminum rod through the round or flat mold, and then coated on the round or flat conductor according to the customer's requirements.

The insulating varnish with temperature index and compatibility, after baking treatment, makes the insulating varnish and the conductor form an integral aluminium winding wires.

According to the insulating paint used, it can be divided into: polyester enameled aluminum wire, polyesterimide enameled aluminum wire, polyamideimide enameled aluminum wire, polyimide enameled aluminum wire, polyesterimide / poly Amide-imide enameled aluminum wire, corona-resistant enameled aluminum wire, as well as oil-based paint, acetal paint, polyurethane enameled aluminum wire, etc.

Sometimes it is also classified according to the speciality of its use, such as self-adhesive enameled aluminum wire, refrigerant resistant enameled aluminum wire, etc.

The Advantages of super enameled aluminium wire

Aluminum is not only cheaper than copper, but also as an excellent conductor, it has better flexibility than copper, its density is only 1/3 of copper, and the same weight of aluminum conducts electricity twice as much as copper, so aluminum Wire requires a larger wire gauge than copper wire to conduct the same current.

Another advantage of enamelled aluminum wire over copper is that the NEMA standard recognizes aluminum wire as a higher thermal class enamelled wire. For example, replacing copper conductors with aluminum conductors and using a high-temperature polyester-laminated polyamide-imide topcoat, the thermal rating can be increased from 200 to 220.

copper vs aluminum wire

copper vs aluminum wire

1)Both copper and aluminum have good electrical conductivity, thermal conductivity and corrosion resistance, so they are often used to make various wires, cables and current-carrying parts.

The density of aluminum is 2.7 grams per cubic centimeter, while the density of copper It is 8.9 grams per cubic centimeter.

The flexibility of aluminum conductors is better than that of copper conductors. In contrast, it is easier to make coils. Because the surface of the enameled aluminum wire has a solid oxide film, it has good insulation effect and long service life.

2). Because of the good insulation of the film layer of the aluminum wire, its heat-resistant temperature is 20°C higher than that of the copper wire.

3). The biggest advantage of using aluminum wire is that the weight is 1/3 lighter than that of copper wire, which greatly reduces production costs and is easy to attach to fixtures.

The Grading of enameled aluminum wire

According to the shape of the conductor, it is divided into: round, flat

Insulation temperature class: 120, 130, 155, 180, 200, 220, etc.

According to different electrical insulation requirements, optional paint film thickness:

According to national standards, it is divided into grade 1 paint film, grade 2 paint film and grade 3 paint film
