Aluminum alum

Aluminum has been known to man since ancient times, though not in its pure form, but as a part of various inorganic clay compounds. In particular, aluminum-potassium alum has long been used in surface dressing, in dyeing fabrics, as well as fire-retardant impregnation. Clays containing aluminum alum have also been used in everyday objects such as amphorae, statuettes , etc.

History of discovery

The first researcher who was able to obtain aluminum chemically was Danish Hans Ersted. However, in 1825 there was no exact technology to separate components which are formed as a result of reaction. In 1827 the experiments were continued by Friedrich Wöhler, and this time successfully. After 20 years of intensive research he succeeded in obtaining silvery-white pellets of light metal, which turned out to be aluminum. Supplier Evek GmbH offers to buy rolled aluminum of domestic and foreign production at an affordable price in a wide range. We provide delivery of products anywhere in the continent. The price is optimum.

Application of

Since the appearance of the metal resembled that of silver, it was primarily of interest to jewelers. The malleability of the metal and its ability to be coated with other elements, particularly gold, led to the production of highly sophisticated jewelry. A new impulse for the growth of aluminum production was given by Bayer and Hall, who suggested an industrial method of producing vtnfkkf by electrolysis of cryolite melt. This technology, with adjustments for technical improvements, is still in operation today.

Mechanical Properties

Technically pure aluminum is characterized by high deformability, plasticity, on the surface forms a thin oxide film of Al2 O3, which prevents further oxidation in the air.

  • Modulus of elasticity, GPa - 68 ... 70;
  • ultimate tensile strength, MPa - 75...84;
  • Relative elongation at tension, % - 22...30;
  • Brinell hardness, HB - 245...285;
  • Tensile strain, % - 85...90 (smaller values - for alloyed aluminum).
