Enameled copper wire is copper wire coated by a insulating paint usually colored red.
The paint is much thinpolyester,polyester-imide,polyester over coated wuth polyamide that other wires have,
yet provide almost the same amount of insulation. Enameled wire is primarily used in the construction of
electromagnets since it allows more loops to be packed into a smaller volume.
After all the effort you put into your hobby project, the painting step is often the most important.
This is the part of your project that people will see the most and a good paint job can make up for any previous mistakes.
Painting on aluminum can be a little tricky.
Good adhesion is the key and requires a mixture of both mechanical and chemical means to provide a long-lasting finish.
Enameling is the process whereby a fine layer of powdered glass is fused to a metal surface to provide a durable and often decorative
covering. While the process dates back to the ancient Greeks, it has most recently been adopted and improved by the automotive industry,
which has developed it into a commercial powder-coating application to produce a high-quality finish for car bodies and parts. Providing you
have access to a kiln, you can learn how to enamel aluminum at home. The technique takes practice and experience to perfect, and you
should initially practice on inexpensive aluminum objects.
