As a professional manufacturer from Hemaokang Steel (Shandong) Co., Ltd., we are proud to introduce our Aluminum Coil for Transformer Windings – 1050 O Temper 1.8mm. This coil is specifically engineered for transformer and electrical equipment applications where high electrical conductivity, ductility, and consistent performance are essential. With our advanced production lines and strict quality control, we deliver aluminum coils that meet the demanding needs of transformer manufacturers worldwide.
Our 1050 O temper aluminum coil offers excellent formability and conductivity, making it an ideal choice for winding conductors in distribution transformers, power transformers, and specialty inductive components. Whether you require standard widths or custom dimensions, our flexible manufacturing capabilities ensure your exact specifications are met.
Key Features & Technical Benefits
- High Electrical Conductivity: 1050 aluminum alloy provides excellent conductivity (approximately 59% IACS minimum), ensuring low energy loss in transformer windings.
- Soft O Temper: Fully annealed condition offers superior bendability and winding ease, reducing stress on insulation and enabling tight, uniform coil construction.
- Accurate Thickness 1.8mm: Maintains tight thickness tolerances for consistent electrical performance and predictable winding dimensions.
- Clean Surfaces & Edges: Burr-free edges and oil-free surfaces help prevent insulation damage and contamination.
- Custom Widths: Available in a range of widths to suit different transformer designs – from narrow strips to full-width coils.
- Consistent Mechanical Properties: Uniform hardness and tensile strength across the entire coil, ensuring stable processing behavior.

Application Advantages
Using 1050 O temper aluminum coil for transformer windings provides several direct benefits to your production and final product performance:
- Reduced Copper Replacement Cost: Aluminum is lighter and more economical than copper while still delivering acceptable electrical performance for many transformer applications.
- Easy Winding Process: The soft annealed temper ensures the material bends smoothly without cracking, even when winding around small radii.
- Lower Weight: Aluminum’s density is only about one-third of copper, reducing the overall weight of transformers – especially important for shipping and installation.
- Enhanced Corrosion Resistance: A natural oxide layer on aluminum provides long-term resistance to atmospheric corrosion.
- Recyclability: 1050 aluminum is fully recyclable, supporting sustainable manufacturing initiatives.

FAQ
-
Is this aluminum coil suitable for dry-type transformer windings?
Yes, 1050 O temper aluminum is widely used in dry-type transformers. Its high conductivity and soft temper allow for easy winding and good electrical performance. -
What is the minimum order quantity (MOQ)?
Our MOQ depends on the width and thickness. For 1.8mm thickness, the typical MOQ is around 3–5 tons. Please contact us to confirm for your specific requirements. -
Can you supply different widths of the same 1.8mm coil?
Yes, we can slit coils to any width from 100mm to 1600mm. Custom widths are available upon request. -
Does the coil have an oil or film coating on the surface?
The surface is clean and dry. We do not apply oil unless specifically requested. A protective film can be added if needed for special handling. -
What kind of packaging do you provide?
We use export-standard packaging: steel pallets, wooden pallets, or coil cradles with waterproof paper and protective strapping. Packaging can be customized to your shipping method. -
How do you ensure the electrical conductivity of the coil?
Each production batch is tested with a conductivity meter. We verify that the material meets ≥59% IACS before shipping. Test certificates are available upon request. -
Can you provide third-party inspection?
Yes, we accept third-party inspections from SGS, BV, or other agencies if required. We will coordinate with the inspector to ensure smooth testing and access.
