Signi aluminium Transformer foil for electrical coil application ranges from 0.18mm to 1.8mm, Several aluminum alloys can be used to meet the minimum industry requirements for strip conductor, but alloy 1060/1070/1350 (99.50% aluminum) is generally the low purity limit employed for this application.
Signi aluminium foil strip is closely controlled to assure smooth, substantially burr-free edges and strip-size availabilities are in capacities exactly equivalent to those of standard copper wire sizes.
