6082 vs 6061 Aluminium: Full Comparison With EN & ASTM Equivalents

A fabricator in Sharjah sends us a 1978 British drawing specifying “HE30-TF bar.” A German RFQ arrives the same week asking for “AlMgSi1, Werkstoff 3.2315.” An American spec sheet wants “UNS A96082 per ASTM B221.” At Aluminium Tubes, we quote all three enquiries the identical metal — because every one of those names is 6082.

The 6082 vs 6061 question isn’t only about which alloy is stronger. For anyone buying across borders, it’s about decoding five decades of designation systems — EN, ASTM, DIN, BS, ISO, AMS — that describe two closely related alloys in a dozen different languages.

This guide settles both halves: the honest property comparison (chemistry, strength, corrosion, anodising), and the complete cross-reference tables that translate any drawing, from a Bavarian machine spec to a legacy British Standard, into the alloy you actually need to order.

The main difference between 6082 and 6061 is chemistry strategy: 6082 uses higher silicon plus manganese for ~10% more strength (up to 340 MPa tensile in T6), while 6061 adds copper and chromium for superior anodising finish and global availability. 6082 is the European structural standard (EN 755-2/EN 485); 6061 is the American equivalent (ASTM B221/B209). They are functional near-equivalents — but certificates are not interchangeable on specified work.

Chemical Composition: Two Recipes for the Same Job

Read the Mn and Cu rows and you’ve understood the whole family feud: 6082 is the manganese alloy, 6061 is the copper alloy. Every downstream difference — strength, finish, corrosion — traces back to those two lines.

Mechanical Properties: The Honest Numbers (T6/T651)

Two honesty notes from daily practice. First, quoted strengths are for small/thin sections — both EN 485/EN 755-2 and ASTM B221 step guaranteed values down as sections thicken, so always design to the table for your size. Second, that identical 70 GPa modulus means deflection-governed designs gain nothing from 6082’s extra strength — the full engineering logic is in our 6061 vs 6082 plate comparison.

The Equivalents Tables: Every Name These Alloys Answer To

This is the section to bookmark. When a drawing from any decade or country lands on your desk, these tables translate it.

Designation Cross-Reference — 6082

Designation Cross-Reference — 6061

Which Standard Governs Which Product Form

The practical rule we repeat daily at Aluminium Tubes: equivalence is metallurgical, not contractual. HE30, 3.2315, AlSi1MgMn, and EN AW-6082 are genuinely the same alloy — but a purchase order written around EN 755-2 is only satisfied by an EN 755-2 certificate. Translate the designation freely; never translate the paperwork without the specifier’s sign-off.

So Which One Should You Buy? The 60-Second Answer

The full decision frameworks live in the form-specific guides — round bar comparison for machined and structural bar work, and the plate comparison for structural plate. The condensed version:

• Specification governs first: ASTM/AMS drawing → 6061. EN/Eurocode drawing → 6082. Legacy HE30/AlMgSi1/3.2315 drawing → modern 6082 with EN certificates.
• Stress-governed structural work with tight margins → 6082’s extra ~10% yield earns its place (see our structural building codes guide for the Eurocode context).
• Cosmetic anodising, imperial sizes, global multi-country supply → 6061.
• Free choice, no spec, no anodising → buy on price and stock; the metals are close enough that logistics should decide.

Common Cross-Border Mistakes (We See These Weekly)

• Treating “equivalent” as “interchangeable” on audited work. A DIN 3.2315 callout supplied as 6061 because “they’re basically the same” fails the material review — the alloys are cousins, not twins, and the certificate mismatch is instant.
• Ordering 6082 for cosmetic anodised parts because the structural calc mentioned it — then rejecting the greyer finish at goods-inwards. Split the BOM: 6082 structure, 6061 visible parts.
• Reading HE30’s “TF” suffix as a mystery. Old British temper codes: TF = solution treated + artificially aged = today’s T6. TB = T4. Translate temper along with alloy.
• Assuming 6082 is unavailable in ASTM paperwork. Newer ASTM B221 editions list 6082 — dual-certified stock exists; ask before redesigning around 6061.

Frequently Asked Questions

Is 6082 equivalent to 6061?

They are functional near-equivalents — both Al-Mg-Si structural alloys with overlapping applications — but not identical. 6082 runs higher silicon plus manganese for ~10% more strength; 6061 carries copper for better anodising. On specified work, supply the exact alloy and certificate the drawing names.

What is the ASTM equivalent of 6082 aluminium?

6082 is registered with the Aluminum Association and appears in newer editions of ASTM B221, so its “ASTM equivalent” is 6082 itself (UNS A96082). Where older American documents need a functional substitute, 6061-T6 is the customary near-equivalent — with engineer approval, since its yield strength is slightly lower.

What is HE30 aluminium?

HE30 is the legacy British Standard designation for extruded 6082 — still common on UK and Gulf drawings from the 1960s–80s. HE30-TF corresponds to modern 6082-T6. Order it today as EN AW-6082 to EN 755-2 and the metallurgy matches the original specification.

Is 6082 stronger than 6061?

Yes, by roughly 8–10% in T6 temper — up to ~340 MPa tensile and ~310 MPa yield for 6082 versus ~310/275 MPa for 6061 in small sections. Both share an identical 70 GPa elastic modulus, so stiffness-governed designs perform the same regardless of which you choose.

Can you weld 6061 to 6082?

Yes — the alloys weld to each other readily using 4043 or 5356 filler, and mixed-alloy fabrications are common. Both lose roughly half their T6 strength in the heat-affected zone, so design welded joints to post-weld properties whichever combination you run.

What is AlSi1MgMn?

AlSi1MgMn is the chemical-symbol designation for 6082 under EN 573-3 and ISO naming — aluminium with ~1% silicon, plus magnesium and manganese. On German drawings it appears as AlMgSi1 or Werkstoff 3.2315; all three names order the same modern alloy: EN AW-6082.
