The use of high pure aluminum

The use of high pure aluminum

The combination of physical, mechanical and chemical properties high pure aluminum determines its wide use practically in all fields of technology, especially in the form of its alloys with other metals.

High pure aluminum obtaining

High pure aluminum obtaining

High pure aluminum can be obtained in three ways: by zone-melting, distillation through subgalogenidy and electrolysis. Of these methods of producing high pure aluminum, industrial utilization was a way to zone melting.

The principle of zone melting is in multiple passage of the molten zone along the ingot of aluminum.

It is necessary to prepare aluminum intended for zone melting, preparation consists in filtering, degassing and etching. Filtering is necessary for removal infusible and solid oxide pellicle, dispersed in the metal, from aluminum.
