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 While it has largely been superseded by more modern standards like GOST 1583-89 , it remains a critical reference for legacy engineering projects, spare part manufacturing, and historical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 : Frequently used as a substitute in various
Several well-known aluminum grades fall under this specification, each tailored for specific industrial needs: is a former Soviet and interstate standard that
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:
As of current industry practices, GOST 2685-75 is considered and has been officially superseded. The primary replacement for general aluminum casting specifications is GOST 1583-89 .
