Aluminium foil and strip supplied for transformer winding, made from pure aluminium with a minimum purity of 99.5% so electrical conductivity is maintained. The production scope covers 1050, 1060 and 1070 alloy in thicknesses of 0.2-3.00 mm and widths of 20-1500 mm, with inner diameters of 150, 200, 300, 400 and 500 mm or customised. Content is 99.6% or above, conductivity 63 %IACS or above and tensile strength above 74 MPa. Strip thickness is specified against the design requirement of the transformer, with commonly used thicknesses ranging from 0.2 mm to 3 mm.
Thickness supplied across 0.2-3.00 mm so the winding can be designed to the transformer rather than adapted to stock sizes
Width from 20-1500 mm means coils can be slit to the winding height instead of being trimmed on site
Content of 99.6% or above and conductivity of 63 %IACS or above keeps winding resistance and heat rise predictable
Tensile strength above 74 MPa lets the foil take winding tension without tearing at the edge
Inner diameter choice of 150 200 300 400 and 500 mm or customised matches the winding machine mandrel already installed
Stock thicknesses that do not match the winding design force the transformer design to be changed
Foil wider or narrower than the winding height has to be trimmed which wastes material and leaves burred edges
Low purity aluminium raises winding resistance and heat rise in service
Coils on the wrong inner diameter do not fit the winding machine mandrel

Aluminium foil at 99.6% content and 63 %IACS or above is the lighter conductor choice for foil wound transformer designs
Transformer foil is supplied at a minimum purity of 99.5% with conductivity and tensile figures stated
Foil winding uses a continuous strip to the winding height while enameled wire builds the winding turn by turn
1050, 1060 and 1070.
Thickness from 0.2-3.00 mm and width from 20-1500 mm. Commonly used thicknesses for transformers range from 0.2 mm to 3 mm.
Content is 99.6% or above with conductivity of 63 %IACS or above, and the foil used in transformers is made from pure aluminium with a minimum purity of 99.5%.
150, 200, 300, 400 and 500 mm, or customised.
Tensile strength is above 74 MPa.
Order quantity and delivery time depend on the thickness, width and alloy specified and are confirmed in writing with the quotation.
