If you are making your own home appliances, gadgets, or even a simple winding for an electromagnetic coil, then you will need the right materials to do so. There are many different types of wires to choose from, but the enameled aluminum wire is one of the most popular and versatile. It is easy to work with, and it will last a long time. There are a few important things to keep in mind when choosing the best type of enameled wire for your project.

Enameled copper or aluminum wire is a metal wire that has been covered with an insulating layer of enamel coating. It is used to wind electromagnetic coils for household appliances, industrial motors, and transformers. It is also commonly used in electrical circuits, because it has a high resistance to corrosion and a durable construction. The insulating coating also protects the conductor from electrical interference and provides a safe barrier against voltage leakage.

The process of producing enameled copper or aluminum wire begins with the bare metal being softened by annealing. Then the conductor is coated with an insulating varnish and baked multiple times. The insulating varnish can be made from a number of different substances, including cellulose, vinyl, or polyester. The coating can be applied by felt or mold painting, and the choice will depend on the size of the conductor.

In general, the insulating paint is a mixture of an epoxy resin with a polyester inferior amine or polyamide imide paint layer. The composition of the insulating coating is adjusted to the production technology, oven temperature, and lacquering conditions. The result is a 200 grades and above high heat-stage aluminium enamel-covered wire with excellent paint film tack, good mechanical properties, and hot and cold properties.

The insulating coating is typically applied in many thin coats, as this helps to ensure that the mechanical and electrical properties of the finished product will be satisfactory. The coating can be further modified to increase the durability of the enamelled copper or aluminium wire for use in harsh environments, such as by adding weldability.

Another option is to use a self-bonding enamel, which can be applied to the bare metal of the conductor and then cured in an autoclave to prevent electrical interference. The resulting enameled metal wire has a very low spring back, good adhesion, and flexibility, and is suitable for high-temperature applications.

Generally, the enamelled aluminum magnet wire is used for interchanging electrical energy with magnetic energy and it is mainly used in household appliances, industrial motor winding, or power transformer winding. It is a major variety of enameled coil and it can be produced according to the customers’ requirements in a wide range of diameters. The tolerances of the bare wire will have a direct impact on the variance of the final coil resistance, so it is necessary to strictly control these parameters.
