: High fluidity, low shrinkage, but not heat-treatable.
The GOST 2685-75 standard quickly gained international recognition and adoption. Its influence extended beyond the Soviet Union, with many countries incorporating its principles into their own national standards. The standard's focus on interchangeability, precision, and efficiency resonated with industries worldwide, from aerospace and automotive to machinery and manufacturing.
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 )

GOST 2685-75 is a valuable standard that provides guidelines for geological and geophysical investigations. This guide has provided an overview of the standard's contents, key aspects, and applications. If you're involved in geological or geophysical work, familiarizing yourself with this standard can help ensure that your investigations meet established requirements and guidelines.

GOST 2685-75 (ГОСТ 2685-75) is a Soviet-era national standard that specified marks, technical requirements and test methods for aluminium casting alloys. It defined composition limits, mechanical and technological properties, quality requirements for castings, and test procedures. The standard has been superseded by later standards (e.g., GOST 1583-89 and subsequent updates), but it remains relevant for understanding historical classifications, legacy drawings, older foundry practice, and inspection of equipment or parts made under that spec.
Blueprints drawn between 1975 and 1993 explicitly list materials like "Alloy AL4 GOST 2685-75 T6." Modern engineers must consult the exact historical document to find the original material limits.
