GOST 2685-75 is a former Soviet national standard, titled in English as "Aluminum Casting Alloys: Grades, Technical Requirements, and Test Methods" . It was officially enacted by the on January 1, 1977 . The standard focused on aluminum alloys specifically designed for creating complex shaped castings (also known as фасонные отливки ). It classified alloys into various categories, including aluminum-silicon, aluminum-silicon-copper, aluminum-copper, and aluminum-magnesium systems, with each category containing specific grades (e.g., AL2, AL4, AL6, AL8).
