Super 37 gauge aluminum wire with enamel coated is a aluminium (Al) wire coated with a very thin layer of insulation. It is used in the construction of transformers, inductors, motors, generators, speakers, hard disk head actuators, electromagnets, electric guitar pickups and other applications that require tight coils of insulated wire.

What Are Wire Enamels?
Wire enamels are applied on copper and aluminum round and flat wires used in motors, transformers, generators and electrical measuring instruments. They are cured onto the wires with heat.

Characteristics and Applications:
Size: A 37-gauge wire is very thin, making it suitable for applications where space is limited.
Conductor Material: Aluminum is lighter than copper, making it useful for weight-sensitive applications.
Enamel Coating: The enamel insulation provides electrical isolation and protects the conductor.
Applications: This type of wire can be used in various electronics applications, including smaller coils, sensors, transformers, and winding applications where space is at a premium.

What is Aluminium magnet wire made of?
Aluminium magnet wire is sometimes used for large transformers and motors. The insulation is typically made of tough polymer film materials rather than vitreous enamel, as the name might suggest. The most suitable materials for magnet wire applications are unalloyed pure metals, particularly copper.
