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 While it has largely been superseded by more modern standards like GOST 1583-89 , it remains a critical reference for legacy engineering projects, spare part manufacturing, and historical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. Scope and Technical Requirements spare part manufacturing
: 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%.
