Re-roll & SemisFrom a rolling ingot of 620mm thickness, a hot rolled coil with a thickness of approximately 3mm can be offered as a "mill product" directly off our hotline. The configuration of our process, with a cold quench of the hot plate and cold finishing, results in special mechanical properties. Our experience in lithographic products assures exceptional surface quality. The re-roll or semi-finished coil can then be used as feedstock for further downstream processing at our customers' facilities. General end applications include foil products, anodized architectural plates/sheets, reflector or heat shield material among others.
Suitable alloy grades are AA1145, AA1235, AA8079. Ideal coil weights are 6 to 7kg per mm of width with an ID of 507mm. If necessary, the coil is rolled to final thickness on the cold mill, thereby offering further gauge reductions to 0.6mm. Annealing operations and final width trimming are optional before quality checks are completed.
