Explore our industrial grade selection of enameled wires and continuous transposed conductors, engineered for maximum electrical conductivity and high temperature tolerance.
In modern electrical engineering, selecting the proper winding conductor is critical for performance and safety. While copper has traditionally been the industry baseline, modern Electrical Aluminum (Al) Wire solutions offer distinct technical benefits. Thanks to advancements in metallurgy, enameled aluminum wire now delivers high conductivity alongside substantial weight savings, helping B2B procurement teams optimize cost and efficiency.
Pure aluminum provides approximately 61% of the conductivity of copper, yet weighs only one-third as much. For applications like massive utility transformers, aerospace components, and automotive motors, using aluminum instead of copper reduces total assembly weight. This directly lowers structural loads and transit costs.
Direct solderability without mechanical stripping. Ideal for precision electronics, high-frequency coils, and small-motor applications.
Rated for temperatures up to 180°C. Delivers robust thermal resistance and mechanical stability for medium-voltage industrial transformers.
Provides robust dielectric strength and excellent adhesion properties. Widely used for standard-duty coils and motors.
Ultimate thermal protection up to 220°C. Engineered to withstand high electrical strain, chemical solvents, and corona discharge.

The primary benefit is weight reduction. Enameled aluminum wire is approximately one-third the weight of copper wire for the same volume, which helps lower assembly weight in large motors and transformers. Additionally, aluminum offers a more stable cost structure compared to copper.
We manufacture enameled wires across several temperature ratings, including Class 130, Class 155, Class 180, Class 200, and Class 220, matching the requirements of diverse operational environments.
CCA enameled wire uses an aluminum core bonded with an outer copper layer. This design offers high-frequency electrical performance close to solid copper due to the skin effect, but at a reduced material cost and overall weight.
CTC consists of individual enameled rectangular wires arranged in a transposed grid pattern. It is primarily used in large-capacity power transformers to decrease winding space requirements and limit electrical eddy current losses.
Yes, our raw materials and manufactured products are fully compliant with RoHS and REACH environmental guidelines. We maintain testing documentation to support standard import clearances.
We provide custom diameters ranging from fine wire gauges to large rectangular profiles, meeting precise slot fill requirements for specialized electric motors and power units.
Our Suzhou facility operates near Shanghai's shipping channels, allowing us to manage sea and air freight logistics efficiently to keep international B2B orders on schedule.
