Non-ferrous Metals

Copper is one of the most required metals. We sort it by the following grades:

• Extra quality – the purest copper only, i.e. wires in electrical cables
• First quality – new copper sheet waste without alloys
• Second quality – old collectable copper free from other metals
• Third quality – old collectable copper containing some impurities (old oxidized gutters etc.)

The brass also contains a high degree of copper. It reaches approximately half the market value of the copper waste. We can find in fittings, various valves, and other assemblies submitted to high erosion, where higher hardness is required than it could be reached by other materials. The brass is also much required among the secondary raw materials, and that is why it is properly stocked, too.

The importance of aluminium in today’s modern world is remarkable. The production of new aluminium from bauxite can not satisfy all the demands; therefore the collection of secondary aluminium is very important. That includes bulky new aluminium residue from production, aluminium shavings from the processing industry, and old collectable aluminium. We sort it into more than 10 grades immediately after acceptance. The grades depend on the quality of aluminium and the purity of fraction. At the acceptance it is divided into the wire (pure or together with the iron feedstock), sheet metal (pure, unalloyed, mixed, non-ferrous, shredded etc.), hard aluminium (pure, with iron), structurals (pure, non-ferrous, and mixed), alloyed wheels, shavings and the slag.

Collected and processed non-ferrous metals contain not only a small portion of bronze that reaches a slightly higher market price as a mixture with copper and tin, but also other non-ferrous metals like zinc, lead mostly found in car batteries, and tin. These metals represent only a small share of the total recovery volume.
