T he primary aluminium industry is one of the largest industries in the world today. World production exceeded 20 million metric tons in 2001 (IAI, 2002) and production is widespread throughout the world. Aluminium as the pure metal or in alloys is used to make a range of products including aircraft, utensils, scientific and domestic apparatus, electrical conductors, and automotive parts. Alumi...

The drawbeads in stamping tools are usually designed based on experience from the forming of steel. However, aluminium alloys display different forming behaviour to steels, which is not reflected in the drawbead design for tools used for stamping aluminium. This paper presents experimental results from different semi-circular drawbead geometries commonly encountered in automotive dies and compa...

The general manufacturing objective during the fabrication of automotive, structural and aerospace components, particularly through flow forming process is to achieve predefined product quality characteristics and mechanical properties with process cost and time constraints. The current state of the economy and the consequent market pressure has forced vehicle manufacturers to simultaneously re...

Production of primary aluminium is energetically enormously expensive. The use secondary (recycled) aluminium, has therefore a high potential to save money and energy while reducing the negative environmental impact production. Although properties alloys are generally comparable those alloys, increased Fe content can lead significant reduction in corrosion resistance these alloys. Secondary AlS...
