Before finalizing your engineering designs, check the metadata in the PDF to see if the standard is marked as or "Заменен" (Replaced) . If it has been replaced by GOST 2685-97, verify with your client or quality assurance team whether the legacy 1975 version is strictly required for compliance.
Specifies the maximum stress the material can withstand while being stretched before breaking.
The GOST 2685-75 standard, titled "Limit deviations of form and position, tolerances, and fits," provided a much-needed solution. This standard established a set of rules for specifying and verifying the form, orientation, and location of features on parts. By defining a unified system of tolerances, fits, and dimensional limits, GOST 2685-75 ensured that parts from different manufacturers could be easily interchanged, reducing production costs and increasing overall efficiency. gost 2685-75 pdf
The point at which the alloy begins to deform plastically. Elongation (%): Measures the ductility of the alloy.
Automotive blocks, aerospace housings, complex marine casings. Aluminum–Silicon–Copper (Al–Si–Cu) Copper-Silumins (АК5М / АЛ5) The GOST 2685-75 standard, titled "Limit deviations of
If you are looking for the GOST 2685-75 PDF, you likely need to verify specifications for . Unlike heavy-duty industrial bearings (e.g., GOST 8338 for radial ball bearings), GOST 2685-75 focuses on small dimensions, ultra-high precision, and low torque .
: Often allows for the highest levels of impurities (up to 2.10% total) to accommodate the rapid cooling and manufacturing process. Key Alloy Examples and Properties The point at which the alloy begins to deform plastically
Alloys governed by this standard were employed in a wide array of demanding industrial applications. AL6 alloy was used for manufacturing shaped castings, and AL8 alloy was suitable for valve parts and other fittings. Alloy AL3 (under GOST 2685-75) was used in precision finishing of switching equipment components. Furthermore, the standard was referenced as the official specification for aluminum cast alloys in the production of pipe fittings.
An important point to note is that . It was superseded by GOST 1583-89 (Aluminum casting alloys. Specifications) on January 1, 1990. Later, GOST 1583-89 itself was replaced by GOST 1583-93.
is a classic Soviet-era interstate standard that established the technical specifications for aluminum casting alloys . While it has largely been superseded by newer versions like GOST 2685-97 in modern manufacturing, it remains a critical reference for maintaining legacy equipment, aerospace components, and historical engineering projects.
