Aluminium can be classified as sheet, plate, foil, extrusion, or casting depending on the production method. 3000 Series: Manganese alloyed, offering good formability and resistance to harsh conditions.
Commercial Alloy Grade Comparisons and Key Differences
7000 Series: Zinc-based alloys delivering the highest strength levels among commercial grades. Cast Alloys Beyond purity, the classification of aluminium expands significantly when distinguishing between wrought and cast alloys.
This processing classification is crucial for engineers, as the method of fabrication significantly impacts the final material's anisotropy, grain structure, and surface finish. Wrought alloys are those processed mechanically—through rolling, forging, or extrusion—to achieve specific shapes and properties.
Commercial Alloy Grade Comparisons and Key Differences
Primary Classification by Purity and Temper The most fundamental way to classify aluminium is by its purity level, which directly correlates with its mechanical properties and workability. These alloys, such as the 6061 or 7075 variants, are the backbone of modern engineering, offering a high strength-to-weight ratio.
