As an aluminum rolling and slitting manufacturer, we produce 1060 H24 pure aluminum strip for transformer windings with controlled chemical composition, stable mechanical properties, accurate dimensions, and clean slit edges. This product is designed for dry-type transformers, oil-immersed transformers, distribution transformers, reactors, and other electromagnetic winding applications where conductivity, formability, and dimensional consistency are important.

1060 aluminum belongs to the commercial pure aluminum series, with aluminum content not less than 99.60%. In H24 temper, the strip has been strain hardened and partially annealed, providing a balanced combination of moderate strength and good bendability. For transformer manufacturers, this balance helps reduce winding deformation while maintaining reliable processing performance during coil winding, insulation wrapping, and assembly.

Factory Supply of 1060 H24 Aluminum Winding Strip

We manufacture 1060 H24 aluminum strip from selected aluminum ingots and qualified rolling stock. The production process includes melting or billet preparation, hot rolling or cast rolling, cold rolling, intermediate annealing when required, precision slitting, edge treatment, cleaning, inspection, and export packaging. Each process is controlled according to customer specifications and applicable international standards.

Our factory supplies aluminum winding strip in customized thicknesses, widths, coil inner diameters, coil weights, and edge conditions. For transformer winding applications, the most common requirements are narrow tolerance, low burr height, smooth surface, and stable electrical conductivity. These requirements directly affect winding efficiency, insulation safety, heat generation, and long-term transformer operation.

For customers seeking a broader product category, our Transformer Aluminium Strip range covers 1050, 1060, 1070, and 1350 aluminum alloys in different tempers for transformer and reactor windings.

Why 1060 H24 Is Used for Transformer Windings

1060 H24 pure aluminum strip is widely used as a conductive winding material because of its high aluminum purity and dependable processing behavior. Compared with some alloyed aluminum grades, 1060 offers better conductivity and excellent corrosion resistance. In transformer windings, conductivity is a key factor that influences load loss and operating efficiency.

The H24 temper is selected when customers require higher strength than fully annealed O temper, while still needing sufficient flexibility for winding operations. During coil winding, the strip must pass through tension control systems, insulation layers, and bending zones without cracking or excessive waviness. Properly produced 1060 H24 aluminum strip can support stable winding tension and reduce the risk of edge damage to insulation paper or film.

Another important reason for using 1060 aluminum strip is its weight advantage. Aluminum has lower density than copper, which can help reduce the total weight of transformer windings and improve material cost control. With correct design and section area, aluminum windings can meet the electrical and thermal requirements of many transformer projects.

Technical Parameters of 1060 H24 Pure Aluminum Strip

The following table shows typical factory supply parameters. Final specifications can be adjusted according to transformer design drawings, winding equipment, and project requirements.

Chemical Composition Reference

1060 aluminum strip is a high-purity aluminum product. The strict control of impurity elements helps maintain conductivity and stable mechanical behavior.

The actual chemical composition is tested and recorded by batch. Material certificates can be provided with each shipment.

Surface and Edge Quality for Winding Performance

For transformer aluminum strip, surface quality is not only an appearance requirement. A clean and smooth surface helps prevent insulation damage and improves winding reliability. We control rolling oil residue, surface scratches, dents, black lines, oxidation, and foreign particles during rolling, cleaning, slitting, and packing.

Edge quality is equally important. Burrs or sharp edges may cut insulation paper, polyester film, Nomex paper, or other insulation materials during winding. Our slitting lines use suitable knives, tension control, and edge inspection methods to maintain clean edges. When required, we can supply deburred or round-edge aluminum strip for higher insulation safety.

Dimensional Accuracy and Coil Stability

Transformer winding equipment usually requires consistent strip width and thickness to maintain uniform coil geometry. Uneven width may affect insulation overlap, while unstable thickness may influence current distribution, temperature rise, and final coil size. For this reason, we apply thickness monitoring during rolling and width inspection after slitting.

Coil stability is also part of our quality control. The aluminum strip coil should be wound tightly and evenly, without telescoping, loose layers, crushed edges, or severe wave. Proper coil shape helps customers load the material onto winding machines efficiently and reduces downtime caused by coil handling issues.

Manufacturing Process in Our Factory

Our production route is arranged according to the thickness, width, temper, and final application. A typical process for 1060 H24 aluminum winding strip includes:

1. Raw material selection and inspection.

2. Rolling stock preparation.

3. Cold rolling to the required intermediate thickness.

4. Annealing control when necessary.

5. Final rolling to achieve H24 temper and target thickness.

6. Surface cleaning and flatness control.

7. Precision slitting to customer width.

8. Edge inspection and burr control.

9. Coil winding, labeling, and packaging.

10. Final inspection and documentation.

This controlled production process allows us to provide repeatable quality for long-term transformer manufacturing programs. Customers who purchase regular quantities can specify stable process routes to improve consistency between batches.

Quality Inspection Before Shipment

Before delivery, we inspect the 1060 H24 aluminum strip according to order requirements. Common inspection items include chemical composition, thickness, width, surface condition, edge condition, coil inner diameter, coil weight, mechanical properties, and conductivity when required. The inspection results are recorded for traceability.

For export orders, we can provide mill test certificates, packing lists, commercial invoices, certificates of origin, and other documents required by the customer or destination market. If the project has specific technical standards, our engineering and quality teams can review the requirements before production.

Applications of 1060 H24 Aluminum Strip

The main application of 1060 H24 pure aluminum strip is transformer winding. It is suitable for:

• Low-voltage transformer windings.

• Distribution transformer windings.

• Dry-type transformer coils.

• Oil-immersed transformer coils.

• Reactor windings.

• Electrical equipment windings.

• Industrial coil and conductor applications.

In addition to transformer grades, we also manufacture general Aluminum Strip products for electrical, packaging, construction, heat exchange, and industrial processing applications.

Packaging for Export Transportation

Aluminum strip for transformer windings must be protected from moisture, impact, and edge damage during transport. Our standard export packaging normally includes moisture-proof paper or film, plastic wrapping, inner and outer protective boards, edge protectors, steel or plastic straps, and wooden pallets or wooden cases. Packaging can be adjusted for sea freight, land transport, or container loading.

Each coil is labeled with alloy, temper, size, coil number, net weight, gross weight, and production batch information. Clear labeling helps customers manage warehouse storage and production traceability.
