GOST 2685-75 mandates specific mechanical properties that must be met during quality assurance testing. Properties vary significantly based on the casting method (Sand vs. Die) and heat treatment condition (T1, T4, T6, etc.).

Note: The table below represents approximate minimum values for Sand Casting (S).

| Alloy Grade | Heat Treatment | Tensile Strength ($\sigma_B$, MPa) | Elongation ($\delta_5$, %) | Brinell Hardness (HB) | | :--- | :--- | :--- | :--- | :--- | | ML5 | T6 (Quench + Age) | 225 – 240 | 3 – 5 | 60 – 65 | | ML10 | T6 | 230 – 260 | 3 – 6 | 60 – 70 | | ML12 | T1 (Artificial Aging) | 210 – 250 | 3 – 5 | 55 – 65 | gost 2685-75 pdf

(Note: Users should consult the official PDF for exact tables, as values differ for Permanent Mold and Die Casting.)

The official custodian of GOST standards is the Euro-Asian Council for Standardization, Metrology and Certification (EASC). In Russia, this is managed by Rosstandart. Note: The table below represents approximate minimum values

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 The standard has been superseded by later standards (e.g., GOST 1583-89 and subsequent updates), but it remains relevant for understanding historical classifications, legacy drawings, older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.

Any legitimate GOST 2685-75 PDF will contain detailed sections on the following technical parameters: GOST 2685-75 (ГОСТ 2685-75) is a Soviet-era national

Even after obtaining the PDF, engineers frequently misinterpret this standard. Avoid these pitfalls:

Note: GOST 2685-75 is a Soviet standard number that can refer to different technical standards depending on the domain (for example, electrical, mechanical, optical, etc.). This post assumes the user is asking about the most commonly referenced GOST 2685-75 concerning photographic film and light sensitivity (photographic exposure) — a frequent topic for historians and engineers — and will flag alternatives at the end. If you meant a different domain, see the “Other possible subjects” note below.

According to the standard, every batch of castings must undergo chemical analysis verification. Mechanical testing involves casting separate test bars alongside the production castings (attached runners) to ensure the material meets the required grade specifications.
