Aluminium Foil and Strip
Aluminium Foil for Transformer
Aluminium foil and strip for transformer windings in alloys 1050, 1060 and 1070, from 0.2 to 3.00 mm thick and 20 to 1500 mm wide, on inner diameters of 150, 200, 300, 400 or 500 mm or customised.
Product Overview
Aluminium foil and strip for transformer windings in alloys 1050, 1060 and 1070, from 0.2 to 3.00 mm thick and 20 to 1500 mm wide, on inner diameters of 150, 200, 300, 400 or 500 mm or customised. Aluminium content is 99.6% or higher, conductivity 63% IACS or better and tensile strength above 74 MPa. Thickness is specified to the transformer design, and commonly used thicknesses range from 0.2 mm to 3 mm.
Key benefits
Why Buyers Choose This Specification
Conductivity Guaranteed at 63% IACS
Winding losses are a direct function of conductivity. A published minimum of 63% IACS is what lets a transformer designer calculate losses rather than assume them.
Width Range of 20 to 1500 mm
Foil winding needs the strip width to match the coil height exactly. A 20 to 1500 mm range covers everything from a small dry-type unit to a large distribution transformer.
Three Alloys in the 1000 Series
1050, 1060 and 1070 differ in purity and therefore in conductivity and softness. Having all three available means the winding machine and the design can both be satisfied.
Inner Diameter to Suit Your Winder
150, 200, 300, 400 and 500 mm as standard or customised, so the coil fits the mandrel you already run.
Application scenarios
Where It Is Used
- Foil winding for dry-type distribution transformers
- Low voltage windings in oil-immersed transformers
- Replacing copper foil where weight and cost matter
- Transformer repair and rewinding work
- Busbar and electrical connection applications
- Coil manufacture requiring specific strip widths
Who it is for
The Buyers This Product Suits
Transformer Manufacturers
Foil winding requires strip matched to coil height, thickness and conductivity, and all three are specified here.
Transformer Repair Shops
Rewinding needs the same alloy and dimensions as the original, available in small quantities.
Buyers Comparing Aluminium With Copper
Published conductivity and tensile figures make the aluminium-versus-copper calculation possible.
Problems it solves
What It Fixes
Winding Losses Higher Than Designed
A conductivity minimum of 63% IACS gives the designer a figure to work from.
Strip Width That Does Not Match the Coil
Widths from 20 to 1500 mm mean the strip is slit to the coil height rather than the coil designed to the strip.
Coils That Do Not Fit the Winding Mandrel
Five standard inner diameters plus custom sizes cover the common winding machines.

Sourcing And Inspection
This product is supplied through TrueGlow Imaging, working with manufacturing partners whose facilities are visited and verified rather than taken on trust. In-process quality control and delivery supervision are available so goods are inspected before the container is sealed. Certifications quoted on this page are those stated on the product specification and belong to that product range rather than to our trading entity, so ask for the certificate covering your specific item.
Handling guide
Getting It Right First Time
Step 1
Specify thickness against the transformer design, within the 0.2 to 3 mm range.
Step 2
Match strip width to the coil height so no trimming is needed at winding.
Step 3
Confirm the inner diameter against your winding mandrel before ordering.
Step 4
Check the surface finish requirement, since it affects insulation adhesion.
Step 5
Store coils dry, because aluminium oxide on the surface affects joint resistance.
