GOST 4784-97 PDF

Full title and description

GOST 4784-97 — "Aluminium and wrought aluminium (aluminum) alloys. Grades." This interstate standard defines the grades (markings), general classification, and principal application forms of wrought aluminum alloys intended for deformation processing (sheets, plates, strips, bars, rods, profiles, tubes, wire, forgings, etc.).

Abstract

GOST 4784-97 establishes the system of grades (trade/designation names) and the basic normative provisions for wrought (deformable) aluminium alloys used as raw material for semi-finished and finished products. The standard was adopted in the late 1990s, later amended, and subsequently superseded by a newer publication that consolidated later revisions of alloy grades and references.

General information

• Status: Withdrawn / superseded; listed as inactive in national catalogs and replaced by a later consolidated standard (GOST 4784-2019).
• Publication date: Adopted 1997 (Interstate Council); introduced as national standard in the Russian Federation from 1 July 2000.
• Publisher: Interstate standard (GOST) — developed under MTC 297 (materials and semi‑finished products from light and special alloys) and introduced via the Russian standards bodies (Gosstandart / Rosstandart).
• ICS / categories: 77.120.10 (Metallurgy — Non‑ferrous metals; Aluminium and aluminium alloys).
• Edition / version: Original designation GOST 4784-97 (1997); amended several times (notable amendments published in the 2000s and 2010s) before being superseded by a 2019 revision.
• Number of pages: Approximately 21 pages (electronic table of contents / official PDF counts).

Scope

Applies to aluminium and wrought (deformable) aluminium alloys intended for manufacture of semi‑finished products by hot or cold deformation (coils, sheets, circles, discs, plates, strips, bars, rods, profiles, tires, tubes, wire, forgings) as well as slabs and ingots used as feedstock. The standard sets out grade names, general designation rules and references to chemical and mechanical requirements established for each grade in related normative documents.

Key topics and requirements

• Designation system and list of wrought aluminum alloy grades (conventional GOST/USSR/CIS grade names and transliterations).
• Main application forms covered: sheets, plates, strips, bars, rods, profiles, tubes, wire, forgings, slabs and ingots.
• Normative references to chemical composition and mechanical property limits for specific grades (via linked GOSTs and technical conditions).
• Rules for marking, packaging and identification of alloy grades for supply and processing.
• Cross-references to predecessor standard GOST 4784-74 and later consolidated revisions; amendments published in the 2000s and 2010s updated grade lists and editorial text.

Typical use and users

Used by metallurgists, aluminium producers, rolling and extrusion mills, suppliers of aluminium semi‑finished products, design and manufacturing engineers in aerospace, transport, construction and general engineering, and standards/quality departments that maintain product specifications or certify material grades for procurement and production.

Related standards

Preceded by GOST 4784-74 (replaced by the 1997 edition); later superseded/updated by a consolidated standard published in 2019 (GOST 4784-2019) that reflects later amendments and grade changes. The standard is often used alongside other material‑specific GOSTs that define chemical composition and mechanical testing methods for individual alloy groups.

FAQ

Q: What is this standard?

A: GOST 4784-97 is an interstate (GOST) standard titled "Aluminium and wrought aluminium alloys. Grades" that defines the system of grade names and basic application forms for deformable aluminium alloys.

Q: What does it cover?

A: It covers the classification and designation (grade names) of wrought aluminium alloys and indicates the types of semi‑finished products and ingots/slabs for which those grades are intended; detailed chemical and mechanical requirements are referenced in associated normative documents.

Q: Who typically uses it?

A: Aluminium producers, mills (rolling/extrusion), material purchasing and QA/QC teams, design and manufacturing engineers in industries that work with wrought aluminium products (aerospace, transport, construction, general engineering).

Q: Is it current or superseded?

A: GOST 4784-97 has been superseded and is listed as withdrawn/inactive in some catalogs; a consolidated successor standard (GOST 4784-2019) was published to replace and update the earlier edition and its amendments. Users should refer to the 2019 revision (or the latest national implementation) for current grade lists and requirements.

Q: Is it part of a series?

A: Yes — it is part of the body of GOST standards for non‑ferrous metals and aluminium alloys (ICS 77.120.10) and interacts with other GOSTs and technical specifications that define chemical compositions, test methods and product-specific requirements.

Q: What are the key keywords?

A: Aluminium, aluminum, wrought alloys, grades, GOST, alloy designation, non‑ferrous metallurgy, sheets, plates, bars, tubes, forgings.
