Introduction Aluminium has been acquiring increasing significance for the past few decades due to its excellent properties and diversified range of applications. Aluminium has been recognized as one of the best candidate materials for various applications by different sectors such as automotive construction aerospace etc. The increasing demand for aluminium-based products and further globalization of the aluminium industry have contributed significantly to the higher consumption of aluminium scrap for re-production of aluminium alloys Mahfoud et al. 2010 . Secondary aluminium alloys are made out of aluminium scrap and workable aluminium garbage by recycling. Production of aluminium alloys belong to heavy source fouling of life environs. Care of environment in industry of aluminium connects with the decreasing consumptions resource as energy materials waters and soil with increase recycling and extension life of products. More than half aluminium on the present produce in European Union comes from recycled raw material. By primary aluminium production we need a lot of energy and constraints decision mining of bauxite so European Union has big interest of share recycling aluminium and therefore increase interest about secondary aluminium alloys and cast stock from them Sencakova Vircikova 2007 . The increase in recycled metal becoming available is a positive trend as secondary aluminium produced from recycled metal requires only about kWh kg of metal produced while primary aluminium production requires about 45 kWh kg produced. It is to the aluminium industry s advantage to maximize the amount of recycled metal for both the energy-savings and the reduction of dependence upon overseas sources. The remelting of recycled metal saves almost 95 of the energy needed to produce prime aluminium from ore .
