Key Advantages

Lightweight compared with copper

Aluminum density is approximately one-third that of copper (2.70 g/cm³ vs. 8.89 g/cm³), significantly reducing overall coil and equipment weight.
Cost-effective

Made from high-quality electrical grade aluminum rods with conductivity after annealing > 62% IACS, offering substantial material cost savings over copper with adequate performance for most applications.
Good electrical conductivity

Conductivity after annealing > 62% IACS, ensuring reliable current transmission for a wide range of electrical equipment.
Good flexibility and winding performance

Sufficient ductility for standard winding processes with strong enamel adhesion, resisting cracking or peeling during coil forming.
Reliable enamel insulation

Premium domestic and imported insulating varnishes with strict thickness control per IEC/NEMA/GB standards, ensuring uniform coating, low pinhole count, and long-term reliability.
Available in different thermal classes

Five thermal classes from 130°C to 220°C with Grade 1/2 insulation options and customization available.
