Superior strength and high heat-resistance, though less fluid during casting. Requires heat treatment. AL8, AL13, AL22, AL23, AL27, AL28
Cylinder heads, engine blocks, pistons, and gearbox housings.
Self-aging properties, meaning they achieve high strength without requiring complex thermal treatment. Applications: Large structural components w Heat Treatment Designations in GOST 2685-75
Despite being developed over 45 years ago, GOST 2685-75 remains a widely recognized and respected standard in the metal cutting industry. The standard's emphasis on performance, safety, and interchangeability has made it an essential reference for manufacturers, engineers, and researchers worldwide.
By studying the GOST 2685-75 PDF, engineers, manufacturers, and researchers can gain a deeper understanding of the standard's significance and applications. gost 2685-75 pdf

GOST 2685-75 is the Soviet/Russian state standard that specifies the technical requirements for aluminum casting alloys
is a former Soviet and interstate standard that established the technical requirements for aluminum casting alloys, including their grades, chemical compositions, and mechanical properties . While it has largely been superseded by more modern standards like GOST 1583-89 , it remains a critical reference for legacy engineering projects, spare part manufacturing, and historical technical documentation.

High-magnesium alloy, known for superior corrosion resistance and strength in marine applications. Boil for only 10 seconds
Several specialized online archives host industrial standards. Look for reputable databases such as:
"To whomever finds this: I am Engineer Viktor Shulgin, Quality Department, Odessa Fish Combine. Date of writing: March 14, 1976. The standard is wrong. Section 7.2.3 requires a 30-second boiling of the sample before organoleptic testing. This destroys the volatile amines that indicate early spoilage. We have had three shipments of sprats rejected in Leningrad because our 'compliant' product tasted fine out of the jar but turned bitter within two weeks. I have submitted a correction proposal to the Standards Committee. They have not responded. If you are reading this, do not follow 7.2.3. Boil for only 10 seconds, or better yet, test cold. The standard was written for heavy metal detection, not human taste. Forgive my handwriting. The archive guard is coming."
