What is Enameled Aluminum Wire?
Enameled aluminum wire is an aluminum conductor that has been coated with a thin, insulating layer of polymer (the "enamel"). This insulation is applied through a process of repeated dipping and baking, creating a uniform, tough, and flexible coating that allows the wire to be wound into tight coils without short-circuiting.

Its primary use is in the construction of electromagnetic components like transformers, motors, inductors, and solenoids.

Key Properties and Characteristics
Conductor: High-purity, electrical-grade aluminum (typically EC-135 or similar).

Insulation: The enamel can be made from various materials, each with different properties:

Polyurethane: Easy to solder without first removing the enamel.

Polyesterimide: Excellent thermal and chemical resistance; the most common type.

Polyamide-imide: Superior thermal Class (220°C and above) and mechanical toughness.

Solderable Polyester: A common, cost-effective option.

Thermal Class: Available in various temperature ratings (e.g., Class 105°C, 130°C, 155°C, 180°C, 200°C) depending on the enamel used.
