Aluminum alloying
Aluminum alloys.
These products are manufactured in Russia in accordance with the provisions of regulations 1583-93 and 4784-2019. The latter document is aligned with the main international standards for such alloys - 209-2007 (ISO) and 573-3-2013 (EN).
The basic classification divides all aluminum alloys into three groups according to criteria such as the production method:
- Forging (stamping).
- Casting.
- Sintering.
Each of these groups is subdivided, in turn, into two subgroups:
- Hardened by heat treatment.
- Uncompleted.
Quenching allows the finished material to have greater heat resistance, hardness, increased strength index and other changes in physical or chemical properties compared to the starting metal.
To achieve these properties, various alloying elements are added to the base aluminum:
- Silumin
- Duralumin
- Beryllium
- Boron
- Bismuth
- Gallium
