High purity aluminium

High purity aluminium

Production of high pure aluminum is one of Slavich Company activities.

We manufacture High Pure Aluminium (Aluminium of semiconductor purity) and Alloys on its base.

Thanks to its technical characteristics and corrosion resistance high purity aluminium and alloys on its base are widely used in semiconductor electronics as the materials for sputtering ohm tracks of integrated circuits, in nuclear power as the materials for sputtering evaporated protection layers and manufacturing specialized equipment.

Aluminium is manufactured according to our own TU (Technical Specification) by a zone melting technique with an additional pretreatment by vacuum endurance and oriented crystallization. Purification is carried out in vacuum with pressure of residual gas 10-5 – 10-8 PA. The method of production has been granted and secured by two patents.

At the customer’s request certification of high purity aluminum is carried out by a mass-spectrometer method on 73 elements in the GIREDMET specialized laboratories (GIREDMET Testint Analytical Center). On test results a Certificate of International Standard is issued.
