Aluminium alloy 1050 is an industry-recognised grade for most general sheet metal work. It has moderate strength & excellent corrosion resistance. An attractive feature of our 1050 material is the highly reflective surface. This is ideal for exposed uses where a decorative impact is desired. Typical uses for aluminium sheet include: Architectural flashing Lamp reflectors Panelling Signs Additionally we recommend a plastic coating on one or both sides for all of our Aluminium Sheet to help protect the surface during transit.
