Selling 1050, 1060, 1070, 1350 H0 Thin Aluminum Strips for Transformer Windings

Aluminum strip is one of the most commonly used conductive materials in transformer manufacturing. Transformer aluminum strips are typically produced through continuous casting, hot rolling, cold rolling, and precision slitting processesto achieve high dimensional accuracy and excellent electrical performance.

Due to its excellent electrical conductivity, lightweight nature, corrosion resistance, and cost-effectiveness, aluminum strip has gradually replaced copper in many transformer winding applications.

1050, 1060, 1070, and 1350 HO aluminum stripsare high-purity aluminum materials specifically designed for transformer windings, dry-type transformers, oil-immersed transformers, and power distribution equipment. These aluminum strips feature stable conductivity, uniform thickness, and smooth surfaces, ensuring efficient energy transmission and reliable transformer performance.

Thin Aluminum Strip Manufacturing Process

High-quality transformer aluminum strip is manufactured through a strict production process to ensure stable performance.

Typical production steps include:

1. High-purity aluminum melting and casting
2. Hot rolling to reduce thickness
3. Cold rolling for precise thickness control
4. Annealing treatment (HO temper)
5. Precision slitting to the required width
6. Surface inspection and quality testing

Each production stage is carefully controlled to guarantee high conductivity, precise dimensions, and excellent surface quality.

Features of Transformer Aluminum Strip

1. Excellent Electrical Conductivity

High-purity aluminum alloys such as 1070 and 1350provide excellent electrical conductivity, ensuring minimal energy loss during power transmission.

2. Excellent Flexibility and Formability

The HO annealed temperensures the aluminum strip is soft and flexible, making it suitable for tight transformer coil winding without cracking or deformation.

3. High Surface Quality

The aluminum strip surface is smooth, clean, and free of scratches, oil stains, or burrs, improving insulation adhesion and ensuring reliable transformer performance.

4. Precise Thickness Control

Advanced rolling technology ensures uniform thickness tolerance, improving the structural stability and consistency of transformer windings.

5. Lightweight and Cost-Effective

Compared with copper, aluminum has lower density and lower cost, reducing the overall manufacturing cost of transformers while maintaining excellent electrical performance.

6. Excellent Corrosion Resistance

Aluminum naturally forms a protective oxide layer, providing strong corrosion resistance and ensuring long-term reliability of transformer components.
