Recycling Non-ferrous Metals
Many years ago, copper and some metals used in copper alloys were thought to be diminishing in supply. Substitutes were sought, for example aluminum and its alloys, and, in the last few years, so-called plastics. However, the concern about diminishing supply of non-ferrous metals was unnecessary. On the one hand mining methods have become better and cheaper, and on the other hand, with more recycling, new metals consumption is much lower. Modern sorting and scrapping methods, which use high tech sorting, can reclaim almost 100 percent of the non-ferrous metals in wrecked cars, electrical appliances, and so forth.
Sorted, non-ferrous metal scrap is valuable input for manufacturing new semi- products, especially for a manufacturer that has no domestic sources for these non-ferrous metal resources. The term "sorted" is important. Mixed scrap has little value because it can hardly be used for manufacturing new semi-products. Mixed scrap can only be processed by refining, which reduces the amount of raw material.
Introducing substitutes has not made non-ferrous metals obsolete; these metals are still important. They are irreplaceable in many industries thanks to their durability, good workability, heat resistance, and recyclablility.
If people choose a material according to its chemical composition, shape, or other properties, they must consider the final product carefully. Kovohutě Čelákovice technicians are ready to recommend the most economical, appropriate, and readily available material.
