Aluminium foil for transformer winding
Aluminium foil for transformer winding have very high conductivity and thermal conductivity, their conductivity is up to about 60%IACS, and forming, welding and corrosion resistance are very good, so it can well meet the performance requirements of aluminum foil for transformer.
Transformer aluminium foil can be used for variable transformer like low or high voltage transformer winding, high frequency transformer,step up or down voltage transformer etc. The alloy can be used to meet the minimum industry requirements for strip conductor, is closely controlled to assure smooth, substantially burr-free edges and strip-size avail-abilities are in capacities exactly equivalent to those of standard copper wire sizes.
In dry type transformers, aluminum winding have been commonly used. Aluminum strip can replace copper conductor in distribution transformers.

Advantages
For example, the principal advantage to using aluminum foil rather than copper in transformers is the reduction in weight. The density of copper is .32117 lbs. per cubic inch while that of aluminum is .09765 lbs. per cubic inch. For a given winding volume, the aluminum winding would weigh one-third the weight of the copper. However, aluminum has only 60% the conductivity of copper. If the winding volume is increased by 40% to raise the aluminum conductivity to that of copper, it still leaves the aluminum coil weighing only 42% of the equivalent copper coil.
