A: The standard recognized that different casting technologies—such as sand casting or pressure die casting—impose different requirements on the alloy's fluidity and tendency to form brittle intermetallic phases. Therefore, strict but method-specific limits were set for iron content.
Includes more complex systems where aluminum is alloyed with other elements for specialized applications.

An international standard is essential for ensuring quality in manufacturing. One such standard is , which regulates aluminum casting alloys.
GOST standards are a set of technical specifications maintained by the Euro-Asian Council for Standardization, Metrology and Certification (EASC). They are widely used across Russia and the Commonwealth of Independent States (CIS).
: Outlines required tensile strength, hardness, and ductility based on the specific casting method and heat treatment applied.
If you meant a different GOST 2685-75 (some GOST numbers were reused across fields), it could instead cover other technical domains. If so, I can:
