Zorba comes in three size fractions; large, small and fine. The market has evolved to treat each grade differently. It prefers the large fraction because it is the easiest to sort using sizing equipment and dense media sorting, or by hand sorting in China.

Zorba is shredded aluminium, which may also contain soft lead, zinc, stainless steel, iron, brass, copper or nickel. Like heavies, zurik is a mixture of metals composed primarily of stainless steel. Zorba and zurik are important designations in international trade.

Zorba Scrap must not contain free iron or large iron attachments. Zorba Aluminum Scrap contains approximately 90% of non-ferrous Aluminum content, and the remaining 10% includes other valuable scrap metals such as copper, brass, lead and so on.
