Product Overview
Aluminium foil and strip for transformer windings in alloys 1050, 1060 and 1070, with thickness from 0.2 to 3.00 mm and width from 20 to 1500 mm. Inner diameter is 150, 200, 300, 400 or 500 mm, or customised. Aluminium content is at least 99.6%, conductivity at least 63% IACS and tensile strength above 74 MPa. Thickness is specified according to the transformer's design requirement rather than supplied in fixed sizes.
Key Benefits
- Conductivity of at least 63% IACS from aluminium of 99.6% minimum content
- Thickness from 0.2 to 3.00 mm to match the transformer design
- Width up to 1500 mm covers most winding machine capacities
- Five standard inner diameters plus customised coils
- Alloys 1050, 1060 and 1070 available
Problems It Solves
- Foil that does not meet the conductivity a design assumes
- Coil inner diameters that do not fit the winding machine
- Width limits that force a design compromise
- Inconsistent material between deliveries

Compared With The Alternatives
| Copper foil for transformers | Copper has far higher conductivity at 99% IACS against 63% for aluminium, but aluminium is lighter and cheaper, so the choice is usually a cost and weight decision at design stage. |
|---|---|
| Round winding wire | Foil windings give a better fill factor and better short circuit strength in many designs; round wire is simpler to handle in small coils. |
Use Guide
- Specify thickness from the transformer design rather than from stock availability
- Confirm the coil inner diameter your winding machine requires
- Check surface condition on arrival, since it affects insulation adhesion
- State conductivity and tensile requirements on the purchase order
