High Recycled Content Aluminium Sheet (3423)

Flat rolled aluminium is produced by casting aluminium through the melting of aluminium ingots / t-bars. The cast coils are then rolled down to the desired thickness in cold rolling mills. Aside from cold rolling, semi-finished cold rolled aluminium sheet production processes may also include annealing, tension levelling, cut-to-length, slitting processes and packaging processes. 

The flat rolled coil & sheet production process begins with the re-melting of unwrought aluminum, aluminum scrap, and alloying elements in the melting furnaces to produce a given alloy chemical composition and casting of coils on twin roll continuous casting lines.

Cast coils are reduced in thickness in successive stages on cold rolling mills to the desired thickness, the coils are slit to the final desired width, and heat-treated in annealing furnaces as required by the metallurgical process to produce final desired mechanical properties.

Finishing operations are performed on slitting, tension levelling, cut-to-length, and packaging lines as needed. Tension levelling lines are used to flatten the material and surface cleaning. Slitting lines are used to reduce the coil width or to slit it into strips. Cut-to-length lines are used to convert coil into sheets in specific lengths.

High recycled content aluminium sheet consists of a special alloy designed by Assan Alüminyum, containing more than 95% non-primary aluminium raw materials.

High recycled content aluminium sheet products are produced through standard flat rolled aluminium production processes, with an input of higher than 95% non-primary aluminium raw materials.
