Why purchased aluminum?

term “cvetmet” It is spoken and implies not only metals but also alloys thereof. In particular, These include, copper, zinc, lead, lead, aluminum, brass, bronze. Today, many companies are buying them from private individuals or organizations, so many are interested in logical question – what to do next? Especially, What's on nonferrous metal scrap Deposit rates They are different and they are often quite high. In the example aluminum can read reuse nonferrous metals. Why purchased aluminum?

where used

Aluminum has found its application in the automotive industry, shipbuilding, aerospace and construction sectors. Besides, the metal used for the manufacture of wire and cable, beverage cans, food foil, as well as an additive to the alloy in the production of plaques, bronze and alloys with zinc.

aluminum Recycling

  1. Secondary treatment process can be described by one of the most used products – beverage cans.
  2. Mechanical pre-treatment – cans are crushed into pieces of irregular shape, sieved through a sieve, to remove sand, coarse dirt and magnetic separate aluminum from other metals.
  3. Thermal removal refinishing – contaminants are removed by burning a material in a furnace and re-sieved aluminum.
  4. Cooking – It represents melting of crushed waste process, which is held in crucible induction furnaces or in the bath.
  5. Cleaning and Filtration – the final stage, when cooked aluminum is filtered to separate metallic impurities.

After recycling the resulting aluminum characterized by three parameters:

  • hydrogen content,
  • alkali metal content,
  • the amount of non-metallic impurities.

In this way, the resulting metal can be re-used in the manufacture, and it is impossible to determine the new product, processed or not.
