: For example, it specifies that the total allowable impurities for sand and shell molding should generally not exceed .

GOST 2685-75 classifies aluminum casting alloys into distinct groups based on their primary alloying elements. These structural groupings determine the material's final mechanical behavior and chemical resistance. Primary Alloy Groups gost 2685-75 pdf

For engineers and manufacturers requiring a PDF of this standard, it is essential to access it through reputable libraries or archival platforms, while always deferring to the current GOST 1583-93 for active production and compliance needs.

Modern Russian standards (GOST R) have replaced many old USSR standards.

: Specifies standards for aluminum alloys used in producing shaped castings through various methods, including sand molding, shell molding, investment casting, and die casting. the standard laid out an alternate

is a classic Soviet-era interstate standard that established the technical specifications for aluminum casting alloys . While it has largely been superseded by newer versions like GOST 2685-97 in modern manufacturing, it remains a critical reference for maintaining legacy equipment, aerospace components, and historical engineering projects.

Under GOST 2685-75, aluminum casting alloys were traditionally designated by the letters (АЛ – Алюминий Литейный ) followed by a sequential number assigned to the alloy formulation (e.g., AL2, AL4, AL9, AL19 ). Concurrently, the standard laid out an alternate, more descriptive chemical labeling system that tracking platforms still recognize: АК (AK) : Aluminum-Silicon system (Silumins) АМ (AM) : Aluminum-Copper system АМг (AMg) : Aluminum-Magnesium system АЦ (ATs) : Aluminum-Zinc system Special suffixes denoted purity levels within the code: ч (ch) : Clean/Pure ( чистый )
