1350 Aluminum — Electrical Grade Strip

The 1350 page on the supplier's coil-strip site is structured differently from the other grade pages, because the product is different: it is a strip for electrical work. The listing describes strip and aluminium foil strip for transformers, alloy 1350, temper O, with round edges free from burr, pits and dents, no scratches, and a cleaned and degreased surface. Its designation is EN AW-1350, Al 99.5 — an electrical-grade purity — and its stated application is electronic transformers and aluminium transformer winding.

1350 also appears in two other published places in this catalogue: the transformer strip family on the full-range site lists 1050, 1060, 1070 and 1350 as its alloys, and the aluminium busbar listing on the English site is a flat bar in 1050/1060/1070/1350. For ordering, the form decides the listing: 1350 strip in coil form is the winding product, while the same electrical alloy family is also supplied as flat bar (busbar). If your requirement is winding strip, quote against this listing; if it is bar, quote against the busbar listing.

Because the 1350 listing publishes its own minimum (2 tons) and its own width range (30–1300 mm), do not carry the figures of the other grade listings onto a 1350 order — the 5 tons per size and 80–2300 mm widths published on the 1050, 1060, 1100 and 3003 grade listings belong to those listings. The figures on this page are the 1350 listing's own, and the quotation for 1350 strip will follow them.

Ordering 1350 strip

Transformer strip is bought against a winding design, so the enquiry should carry the design's strip width and thickness, the total tonnage, and the coil format your winding machine takes — the listing publishes inner diameters of 150, 300 and 500 mm, which are smaller than the general grade range because winding coils are handled differently from mother coil. Edge condition is already specified by the listing (round, burr-free, cleaned and degreased); if your winding process needs a different edge or a slit-to-width programme across several widths, list the widths — strip programmes are normally quoted as a set.

Note the payment terms published on this listing — T/T or irrevocable L/C at sight — which differ in detail from the T/T-only wording of the standard grade pages. The 1350 listing stands on its own figures: its dimensions, minimum and terms are the ones that apply to 1350 strip, so do not cross-reference the other grade listings' figures onto it.
