GOST 4784-2019 PDF

Full title and description

GOST 4784-2019 — "Алюминий и сплавы алюминиевые деформируемые. Марки" (English: "Aluminium and wrought aluminium alloys. Grades"). The standard establishes the system of designation and the list of grades (marks) of aluminium and wrought aluminium alloys used for production of semi-finished products and ingots/slabs.

Abstract

GOST 4784-2019 defines grades (marks) of aluminium and deformable (wrought) aluminium alloys, their chemical composition limits and designation system applicable to wrought products (sheets, strips, plates, rods, profiles, wire, forgings and stamped forgings), as well as slabs and ingots. It replaces the earlier GOST 4784-97 and aligns the national grade list with related international references where applicable.

Scope

The standard applies to aluminium and deformable (wrought) aluminium alloys intended for manufacture of semi-finished products — tapes in rolls, sheets, disk-circles, plates, strips, rods, profiles, panels, tyres, pipes, wire rod, wire, forgings and stamped forgings — produced by hot or cold deformation, and also to slabs and ingots. It establishes grade designations and composition limits used for selection, procurement and technical documentation.

Key topics and requirements

• List of aluminium and wrought-aluminium grades (marks) and their letter/number designations.
• Permissible ranges for major alloying elements (e.g., Mg, Si, Fe, Cu, Mn, Zn, Ti and others) for each grade.
• Rules for grade designation and marking of wrought products and ingots/slabs.
• References and alignment notes to related international standards (notably EN/ISO documents cited in the normative references of the standard).
• Annexes/changes: the text includes subsequent amendments and corrections that update certain table entries (chemical limits, new grades, editorial corrections).

Typical use and users

Used by aluminium producers, mill product manufacturers, metal traders, procurement and quality departments, designers and engineers specifying materials for fabrication and forming processes. It is a primary reference for selecting alloy grades for rolled, extruded and drawn wrought products and for preparing product specifications and certificates of conformity.

Related standards

Normative and related references include the superseded GOST 4784-97, national standards on primary aluminium and ingots, and international documents referenced in the standard (e.g., EN 573-3 and ISO 209 series where equivalence or citation is indicated). National normative cross-references and later GOST documents on aluminium semi-finished products are often used together with GOST 4784-2019.

FAQ

Q: What is this standard?

A: GOST 4784-2019 is the Russian/interstate standard that lists grades (marks) of aluminium and deformable (wrought) aluminium alloys and defines their designation and composition limits for wrought products and ingots/slabs.

Q: What does it cover?

A: It covers the system of grade names and numeric/letter designations, permissible chemical composition ranges for each grade, and applicability to a wide range of semi-finished wrought products (sheets, strips, rods, profiles, wire, forgings, etc.). It does not itself give detailed mechanical property tables for every product form (those are specified in product-specific standards or technical specifications).

Q: Who typically uses it?

A: Aluminium mills, fabricators, specifiers, procurement and quality-control personnel, testing laboratories and standards bodies — anyone who needs to identify or verify the grade/chemistry of wrought aluminium used in manufacturing and trade.

Q: Is it current or superseded?

A: GOST 4784-2019 is the current (2019) edition that superseded GOST 4784-97; it has received amendments and corrections since publication (amendments published in 2023 and later). Check the official consolidated text or national catalogues for the current consolidated version.

Q: Is it part of a series?

A: It is a product (grades) standard within the suite of metallurgical and aluminium-sector standards (ICS 77.120.10) and is commonly used alongside product- or form-specific GOSTs and technical specifications for rolled, extruded or drawn aluminium products. It also cites or relates to certain EN/ISO references noted in the normative section.

Q: What are the key keywords?

A: Aluminium, wrought alloys, grades, marks, chemical composition, designation, semi-finished products, slabs, ingots.
