Aluminium cans come from the drinks industry. Some cans – mainly imported ones – have steel lids or bases. (Switzerland: the official collection organisation for drink cans is IGORA).
Aluminium dross is a by-product of aluminium casting. The dross floats on the surface of the molten metal, together with impurities.
Cast aluminium is made hard and brittle by alloying additives.
Aluminium overhead power lines
Aluminium overhead power lines can be all aluminium, or reinforced with steel or stainless steel wire strands.
Plain aluminium profiles
Plain aluminium profiles are production waste – often from the windowindustry. Alloying with magnesium and silicon makes them tough and torsionally stiff.
Old/coloured and/or anodised aluminium profile
Old/coloured and/or anodised aluminium profiles are used products that often arise when windows are replaced.
New aluminium refers to plain sheet production waste. Some of this material is still covered with protective film.
Old aluminium refers to used products such as vacuum cleaner tubes and milk churns.
