Can we customize Russian standard aluminum alloys even if we only have old Russian standard drawings?

Absolutely!

Even if you only have legacy Russian / Soviet drawings, Russian-grade designations, incomplete GOST / OST / TU standards, chemical composition tables, or material markings from old equipment, Chalco can assist in evaluation and formalize a confirmable, quotable custom Russian standard aluminum alloy requirement.

What can Chalco help confirm? Chalco does not simply substitute standard aluminum alloys for Russian standard grades.

• Russian grade identification — Confirm original Cyrillic designation, Latin transliteration, and possible spelling variations, e.g., В93 / V93 / B93, Д19ч / D19ch.
• Russian standard aluminum alloy chemical composition confirmation — Evaluate chemical composition requirements based on grade, standard, or customer-provided composition table.
• Custom alloy production by chemical composition — For Russian grades, assess whether custom melting, ingot, or slab preparation is required prior to rolling.
• Rolled product form confirmation — Confirm whether the material should be produced as aluminum sheet, plate, coil, strip, foil, or circle.
• Specification, temper, and certification documentation confirmation — Confirm thickness, width, length, coil diameter, temper, surface finish, tolerances, MTC, batch traceability, and export documentation requirements.

We first evaluate based on legacy drawings, Russian grades, chemical composition, and project standards. When necessary, we assess custom ingot or slab routes before rolling into aluminum sheet, plate, coil, strip, foil, or circle.

Why do many projects still require russian-standard aluminum alloys?

Many legacy aviation, MRO, defense maintenance, marine, rail, and industrial projects still require Russian / Soviet-standard aluminum alloys because original drawings, bills of materials, and acceptance documents were written according to Russian or Soviet standards.

Continuity with original drawing requirements — alloy designations such as Д19ч, В93, 1420, 1163, and 1985ч may still appear in legacy drawings, maintenance manuals, and project documentation.

Meeting project acceptance criteria — some projects require materials supplied per GOST, OST, TU, or customer-specific standards, accompanied by MTC and batch traceability documentation.

Ensuring consistency in maintenance and replacement — for aging equipment and MRO projects, evaluating materials by Russian alloy designation reduces the risk of material mismatch during repair or replacement.

Supporting material reproduction by composition — if the original supply chain is no longer accessible, material availability can be reassessed based on chemical composition, product form, and project standards.

Notes on identifying Russian alloy designations

Russian alloy designations typically use uppercase Cyrillic letters. However, in legacy Soviet drawings, scanned documents, and typed material lists, mixed case, Latin transliteration variations, or letter-digit ambiguities may occur.

In GOST alloy designations, certain letters have different meanings when used alone versus in combination. For example, Мц / Mts denotes manganese in aluminum and copper alloys, while М / M alone may indicate copper. Ц / Ts is typically associated with zinc. If legacy drawings are unclear, alloy identification should be confirmed alongside chemical composition tables.

In legacy Soviet drawings or documents, some Cyrillic letters are easily confused with numerals. For instance, З may be mistaken for 3, and О for 0. This commonly occurs in scanned drawings, photocopied material lists, or documents produced on old typewriters.

Common Russian alloy designation confusions:

• В93 / V93 / B93 — the Cyrillic letter В is usually transliterated as V, but may appear as B in export documentation.
• Д19 / Д19ч / D19ch — when matching legacy drawings, the suffix ч should not be omitted arbitrarily.
• Сил1С / Sil1S and Сил2С / Sil2S — digits and Cyrillic letters require careful verification.
• З / 3, О / 0 — letter-digit confusion may occur in old typewritten documents.

If you are unsure whether a Russian alloy designation in your drawing has been correctly identified, please send the original Russian drawing, material marking, chemical composition table, or GOST / OST / TU standard number.

Chalco can assist in verifying Russian alloy designations prior to quotation to reduce the risk of selecting the wrong Russian-standard aluminum alloy.

Notes on similar grades and substitution risks for Russian-standard alloys

Many Russian / Soviet-standard aluminum alloys may have approximate equivalents in the AA, EN, or other international systems, but 'similar' does not mean direct substitution is acceptable.

For example, В93 / V93 may be approximately compared to certain 7xxx-series alloys, Д19ч / D19ch may be referenced against select 2xxx-series alloys, and 1420 should generally be evaluated individually as a Russian Al-Li (aluminum-lithium) alloy per project requirements.

Reference table of similar Russian-standard alloy designations:

Chalco can assist customers in comparing Russian alloy designations with AA / EN alloys based on chemical composition, temper, product form, mechanical properties, and project standards.

Final substitution eligibility must be determined by customer drawings, engineering approval, and the final MTC.
