AMAG AL4®FOIL foil stock

About this product

AMAG AL4®FOIL. FOIL STOCK FOR SUSTAINABLE ALUMINIUM PACKAGING. AMAG aluminum impresses with its impermeability to light, gases and moisture when used in flexible laminates in technical applications and for packaging food and beverages. The production of surface-sensitive foil stock materials is an important part of AMAG's extensive product portfolio. High-quality primary material is needed to produce high-quality aluminium foil. AMAG has been supplying top quality foil stock aluminium coils to leading European foil manufacturers for many years. AMAG uses special alloys and sophisticated process control to ensure that the primary material is of high quality. This results in products with excellent mechanical properties and a low carbon footprint. The material is also available as ASI-certified aluminium. The waste generated during production can be recycled into high-quality wrought alloys using customized closed-loop concepts and state-of-the-art recycling technology. AMAG foil stock coils are supplied in alloy classes 1xxx, 3xxx, 8xxx and in grades F, H18 and H199 in the thickness range between 0.3 - 0.6 mm and a final width of up to 2,250 mm. Typical production route of aluminium foils: The commercial production route of aluminium foil starts with continuous casting ingots, which are typically heated at temperatures between 500 to 600 °C prior to hot rolling. The material is then processed by hot and cold rolling at AMAG and delivered to the customers. The customer typically subjects the material to intermediate annealing and rolls it to the final foil thickness in several passes. A precisely defined final annealing and final multi-stage finishing process is carried out according to each specification. Fe is the essential main alloying element for 8xxx foil applications, as it provides the required combination of strength and elongation needed for packaging materials. In addition to providing higher strength, increasing the Fe content even has a positive effect on formability. By optimizing the properties, the foil can be "downgauged", which reduces the weight of the packaging and thus the material input and carbon footprint.
