Aluminium KhCh is characterized by relatively high ductility, chemical resistance, electrical conductivity, and easily applied in electrical engineering, chemistry, and other fields. Unalloyed aluminum has used in the manufacture of rectifiers, capacitors, semiconducting appliances, transformers, cables massive, microcircuits. Also high purity aluminum A 999 successfully replaces copper. This aluminum is produced in three ways: through subhalide distillation, zone melting, electrolysis of organic aluminum compounds. zone melting method is most in demand in the domestic industry. According to GOST 11069-74 (still relevant in the CIS), high purity aluminum A 999 may contain a total of less than 0.001% of impurities. This zinc, silicon, titanium, copper, iron and other ingredients which do not affect, however, the properties of commercial aluminum. The material can also be labeled as aluminum A5N - compositions of the two marks are identical. Product aluminum is produced in the form of pellets, wires, rods, powders, ingots, shavings, bars, ribbons, rods, flakes, tablets, cones and other products. The products comply with a number of different standards. Available usually in small lots (0.3 kg), there are many forms of delivery. In particular, the dosage granules are normalized diameter, packed in plastic containers, each consignment is accompanied by a certificate.
