Aluminium plate, sheet, bar, pipe and structural sections in the 1050, 5052, 5083, 5086, 5454, 6061, 6082 and 7075 grades — one third the weight of steel with excellent corrosion resistance and conductivity.
Aluminium is the light structural metal: density 2.7 g/cm³ versus 7.85 for steel, a naturally forming oxide film that resists atmosphere and water without coating, and full recyclability. Grade choice drives the properties — pure 1050 for conductivity and forming; the magnesium 5xxx family (5052, 5083, 5086, 5454) for marine, cryogenic and tank strength; 6061/6082 for weldable structural work and 7075 for the highest strength-to-weight ratio.
We supply aluminium as plate and sheet for fabrication, bars and rods for machining, pipe and tube for lightweight services, and standard structural sections. Tempers are certified (O, H, T6) and material ships with EN 10204 inspection documents.
The grades below are the ones most often asked for. Each grade stays on this page — the material-first way to browse.
UNS A91050 EN / W.Nr. 3.0225 (1050A)
99.5% pure aluminium — the commercial-purity grade. Highest formability and electrical conductivity of the series. Busbars, heat-exchanger fins, chemical equipment, trim and general sheet-metal work.
UNS A95052
Al-Mg2.5 — the general-purpose workhorse of the 5xxx sheet family. Excellent formability for bending and deep drawing, good seawater and chemical resistance and moderate strength in H32/H34 tempers. Fuel and oil tanks, marine panels, pressure vessels, sheet-metal enclosures and signage.
UNS A95083 EN / W.Nr. 3.3547
Al-Mg4.5Mn — the marine grade. High strength in the work-hardened H116/H321 tempers, excellent seawater corrosion resistance and retained toughness at cryogenic temperature. Hull plating, LNG-support structures, pressure vessels and rail cars.
UNS A95086
Al-Mg4 — between 5052 and 5083 in strength with the best combination of formability and corrosion resistance of the marine grades. Hull and deck plating, welded storage tanks, pressure vessels and cryogenic equipment.
UNS A95454
Al-Mg2.7Mn — the elevated-temperature and hydrogen-service member of the marine family, resistant to blistering in hot seawater and to stress-corrosion cracking. Chemical and product tankers, pipelines, exhaust systems and welded structures working above 65 °C.
UNS A96061
Al-Mg-Si heat-treatable alloy, the general engineering grade (the 6082 counterpart in ASTM markets). Good weldability, machinability in T6 and medium strength — structures, frames, pipe fittings and machined plates.
EN / W.Nr. 3.2315
The European structural Al-Si-Mg grade — slightly stronger than 6061 with the same excellent weldability. Scaffolding, cranes, transport frames, and T6 plates and bars for machined components.
UNS A97075 EN / W.Nr. 3.4345
Al-Zn-Mg-Cu — the strongest aluminium. High strength-to-weight for aerospace structures, mould plates, die components and high-stress fittings. Not recommended for welding; supplied in T6 and T651.

Aluminium products are supplied to ASTM or EN specifications with temper certification and EN 10204 Type 3.1 inspection documents. Marine-tempers (5083 H116 / H321) can be supplied with classification-society certificates on request — confirm the society and scope with your enquiry. Chemical and mechanical test reports accompany each lot.
They are the same alloy family (Al-Mg-Si) on different standards: 6061 is the ASTM (US) designation, 6082 the EN (European) one with slightly higher strength. Properties and welding behaviour are close enough that availability and the customer standard usually decide.
The 5xxx (5083) and 6xxx (6061, 6082) grades weld very well with TIG/MIG and 5356/4043 filler. 7075 is generally not weldable — it hot-cracks — so it is used with bolted or riveted joints and machined from solid.
5083 in the H116 or H321 temper — magnesium gives it seawater corrosion resistance and work-hardened strength. It is the standard hull and superstructure grade and stays tough at cryogenic temperatures.
About one third of the weight for the same volume (2.7 vs 7.85 g/cm³). Per kilogram of strength, 6082-T6 and 7075-T6 are competitive with structural steel — which is why transport structures use them.
O is annealed (soft, most formable); H is strain-hardened (H116/H321 are marine tempers of 5083); T6 is solution-treated and artificially aged — the strong, standard condition for 6061/6082/7075. Material ships certified to the ordered temper.
