Aluminium Strip in Coil
After completion of the rolling process, the coils can be slit to the width, required for further processing.
The finished coils can be supplied in various tempers following the specific requirement or application.
The coils are used either or further internal processing to circles, sheets or foils or sold to the final user according to their requirements.
It is called coil or coiled sheet when the thickness range lies between 0,40 mm up to max 6 mm in widths up to 1500 mm or 2500 mm for vehicle construction.
There are endless qualities on the market, but most manufacturers comply with the international standards: EN-573, EN-485
Aluminium sheets are sheared from coils, and are available in a wide range of sizes, alloys and tempers.
Most commonly: commercial aluminium sheet is produced in alloys:
1050 or 1100, 3003, 5005, 5052, 5086 and 5754
Heat treatment to various tempers following the technical requirements for the specific application.
The thickness range may start from 0,15 mm for special applications, however commercial, cold-rolled sheets are mainly produced from 0.4 mm up to max 6 mm in widths up to 1500 mm or 2500 mm for vehicle construction.
There are different qualities on the market, but most manufacturers comply with the international standards: EN- 573, EN-485.
0,4 mm Foil stock is the basis for the production of foil. The strip is rolled back to a very fine gauge of 6 My for household foil The foil is rolled on special machines, using two cols run against each other, to avoid breakage and other damages.
All commercial alloys can be used, de pending on the eventual application of the foil;
1050 up to 1350, 3003, 3004, 3005, but especially modern alloys in the 8000 series in various tempers are used, always according to the international standards: EN-573, EN-485
The packaging industry especially, but also the de technical sector is a large consumer of specialised foils for sustainable applications.
Circles and some smaller traffic signs are blanked from cold rolled coil up to a diameter of appr 650 mm. Beyond this size they are sheared to size.
The product is therefore only available if a suitable tool is in use for the required circle size and thickness.
Square, rectangular and triangular road signs must normally be sheared to shape and size.
Normally all commercial alloys can be used for circles: 1050 up to 1350, 3003, 3004, 3005, 5005, 5052, 5086 and 5754, but also alloys in the 8000 series, in various tempers to the commercial standards EN-573, EN-485
