Enameled copper wire, commonly known as magnet wire, is a copper conductor coated with a thin, uniform insulation layer (typically enamel).
Alcutrans offers a wide range of enameled copper winding wires designed to deliver excellent tensile strength, elongation, and long-term reliability.

The enamel coating protects the copper conductor from moisture, chemical exposure, and environmental stress, ensuring consistent performance across demanding electrical and industrial applications.

Enamel Coating Types & Thermal Classes

Alcutrans supplies enameled copper winding wires with insulation systems ranging from Thermal Class 105°C to 240°C, including:

• Polyvinyl Acetal
• Modified Polyester
• Polyester-Imide
• Polyamide-Imide
• Aromatic Polyimide
• Polyurethane
• Corona Resistance Enamel

Each coating type provides specific advantages, making it suitable for applications ranging from general electrical use to advanced industrial environments where high temperature, mechanical stress, and durability are critical.

Material Excellence

The conductors are made from electrolytically refined copper, fully annealed to ensure optimal ductility and performance. This enables reliable winding, superior formability, and consistent results in precision-driven applications.

Key Benefits of Enameled Copper Winding Wires

• High Ductility: Copper elongation of 20–40% ensures excellent flexibility and formability.
• Low Resistivity: High electrical conductivity helps reduce resistance versus alternative conductor materials.
• High Fatigue Resistance: Good elasticity helps minimize breakage during winding operations.
• Low Voltage Drop: Lower resistivity supports better voltage quality over longer transmission distances.
• Low Electrical Loss: Reduced resistive losses improve energy efficiency.
• Lower Heat Generation: For the same current and cross-section, copper generates less heat for safer, more reliable operation.
