: Known for higher magnesium content (9.3–10%), this grade offers improved mechanical properties, which can be further enhanced by 15–20% if iron and silicon impurities are limited to 0.030%.

The GOST 2685-75 standard covers aluminum alloys intended for the production of shaped castings. It classifies alloys based on their chemical composition and the specific casting method used, such as:

: Used for high-precision components.

The Document is Replaced With: * GOST 1583-89: Aluminium casting alloys. Specifications. * GOST 2685-63: Aluminium casting alloys. auremo.biz Alloy АЛ6 - Auremo

is a former Soviet and interstate standard that established the technical requirements for aluminum casting alloys, including their grades, chemical compositions, and mechanical properties . While it has largely been superseded by more modern standards like GOST 1583-89 , it remains a critical reference for legacy engineering projects, spare part manufacturing, and historical technical documentation.
