Abstract

Aluminium and its alloys are considered as the most important in the series of low
density materials which have different industrial applications to justify the need for
low density suitable for advanced technology. As a result of increasing the cost of
metals and their alloys during the last years, there were critical needs to get the
engineering materials from their scraps; especially for aluminium alloys which have
low melting temperatures. It is world wide known that 40% of the total production of
high quality aluminium and its alloys from their scraps which need low energy around
90% less than that required for production aluminium from ore.
In this study, different scraps of aluminium and its alloys (wrought and casting) were
determined. These alloys were collected from scraps of work shops, industry, ingots,
used cans, used home appliance and equipments. It was found that there are no
information regarding these scraps from industrial and environmental representatives.
In order to obtain new products from these scraps, it requires knowing the quality of
them. In spite of importance of this industry, it still a traditional and applied without
any scientific or technological aspects.
