Alloy Grades: Covers common cast aluminum alloys such as AL4 (АЛ4), AL9 (АЛ9), and AL19 (АЛ19). Technical Requirements: GOST 2685-75 is the Soviet/Russian state standard for
Several well-known aluminum grades fall under this specification, each tailored for specific industrial needs: English Translations : Alloy Grades : Covers common
: Detailed tables list the allowable percentages of primary elements (Aluminum, Silicon, Copper, Magnesium) and maximum limits for impurities like Iron. Mechanical Properties : It sets minimum requirements for: Tensile Strength ( sigma sub cap B : Typically measured in MPa. Elongation ( : The percentage increase in length before failure. : Usually specified as Brinell hardness (HB). Casting Methods
As of current industry practices, GOST 2685-75 is considered not effective and has been officially superseded. The primary replacement for general aluminum casting specifications is GOST 1583-89.
