Aluminum colored wire is an electromagnetic wire mainly made of electrical pure aluminum as the conductor material, and coated with a layer of insulating paint film on its surface. Electrical pure aluminum, with a purity usually above 99.95%, has a relatively low density (about 2.7E3 kg/M3), is lighter than copper, but has slightly lower conductivity than copper, generally 61.8% IACS (International Annealed Copper Standard).

Enamelled aluminum wire is widely used in various electrical equipment, such as motors, transformers, solenoid valves, and household appliances, due to its lighter weight, lower cost, and good conductivity.

Advantages and Applications of Aluminium Enameled Wire
Advantages of aluminum magnet wire:
Cost effectiveness: Aluminum is relatively cheaper than copper, so using aluminum as a conductor for aluminium winding wire has a significant cost advantage

Lightweight: Aluminum has a lower density than copper, and under the same current carrying capacity, aluminum enameled wire is lighter in weight

Technological progress: With the improvement of surface treatment technology and insulation paint formula, the electrical and mechanical properties of modern aluminum colored wire have been greatly improved, especially when combined with high-performance insulation paint to replace copper enameled wires within a certain range.

Application exploration:

The motor industry and transformer industry

electronic devices: Especially in compact designs, lightweight aluminum enameled wires are beneficial for optimizing spatial layout.

New energy fields: In the new energy industries such as electric vehicles, wind power, and photovoltaics, enameled magnet wire and aluminum enameled wires are widely used in power transmission links such as motor drives and battery management systems due to their lightweight and low-cost characteristics.

Although enamelled aluminum winding wire has the above advantages, its conductivity is lower than that of copper enameled wire. Therefore, in some situations where high conductivity is required and weight restrictions are not significant, copper enameled wire is still the preferred choice.

FAQs of Enameled Aluminium Winding Wire
What is the diameter range of insulated aluminum wire?
Regarding polyurethane (UEW) aluminum enameled wire-155C Polyurethane Enameled Aluminum Wire, the factory often produces a range of 0.12-0.40mm

For other types (QZ/QZY/QZYXY/QXY) aluminum enameled wire, it is generally 0.17-3.00MM

Can we offer special colors magnet wire aluminum?
The polyurethane series enameled wire can accept customized colors from customers, but the minimum order quantity is about 3 tons (because the minimum order quantity for customized colored Varnish is 1 ton).

What are the types of wire reels for aluminium enamelled wire?
0.12-0.19mm: PT4-PT10-PT15 type bobbin
0.20-1.00mm: PT25/PT60 type bobbin
1.00-3.00mm: PT25/PT60/PT200 type bobbin

Can we provide Testing samples for aluminium magnet wire?
If the factory has customers who require specification samples, we provide them free of charge (usually not exceeding 1KG).

If arrangements need to be made overseas, the customer needs to provide detailed international express delivery information.
