Aluminium Round Bar
Aluminium round bar: 6061 and 6082 for general machining, 7075 and 2024 for high strength, and 5083 for seawater applications. We cut pieces to the length you need, in any quantity.
Grades and sizes
2024
A high-strength, heat-treatable aluminium alloy with copper (about 4 %) and magnesium. It has high fatigue strength and good machinability. Because its corrosion resistance is low, it is protected by cladding or anodising in outdoor service; it is not suitable for fusion welding, so joints are usually riveted or bolted. Used for aerospace structural parts, highly loaded machine parts, fixtures and fasteners.
Bar standard: EN 755-2 (extruded) · EN 754-2 (cold drawn)
5083
A non-heat-treatable aluminium alloy with about 4.5 % magnesium. It has very high corrosion resistance to seawater and industrial atmospheres, is one of the strongest non-heat-treatable alloys and retains most of its strength after welding. It keeps its toughness at low temperatures and is therefore used for cryogenic tanks; continuous service above 65 °C is not recommended. Preferred for ship and boat hulls, pressure vessels, tankers and silos, and mould base plates.
Bar standard: EN 755-2 (extruded) · EN 754-2 (cold drawn)
6061
A general-purpose, heat-treatable structural alloy with magnesium, silicon and a small copper content. In the T6 temper it combines good strength, corrosion resistance and weldability, and it is easy to machine and anodise. Its properties are very close to those of 6082, and it is frequently specified on drawings prepared to American (ASTM) standards. Used for machine and fixture parts, profiles, fittings, and automotive and marine applications.
Bar standard: EN 755-2 (extruded) · EN 754-2 (cold drawn)
6082
A heat-treatable structural alloy with silicon, magnesium and manganese. It is one of the highest-strength alloys in the 6xxx series; the manganese addition controls the grain structure and raises strength. It is the most widely used machining and structural alloy for bar, flat bar and plate in Europe; in the T6/T651 temper it machines well, is weldable and is suitable for anodising. Used for machine parts, load-bearing structures, crane and bridge components, and moulds and fixtures.
Bar standard: EN 755-2 (extruded) · EN 754-2 (cold drawn)
7075
A heat-treatable aluminium alloy with zinc (about 5.5 %), magnesium and copper. In the T6/T651 temper it is one of the strongest aluminium alloys, with strength comparable to many structural steels. It machines well and can be polished; it is not suitable for fusion welding, and its corrosion resistance is moderate. Used for injection and blow moulds, aerospace parts, fixtures and highly loaded machine parts.

Frequently asked questions
Can I get round bar in a special length?
The standard length is 3 metres, and we cut pieces to the length you need, in any quantity. If a different mill length is required, it can be made to order with a minimum of 300 kg.
What are the designations for 2024, 5083, 6061, 6082 and 7075?
2024: AlCu4Mg1, EN AW-2024, DIN 3.1355. 5083: AlMg4,5Mn0,7, EN AW-5083, DIN 3.3547. 6061: AlMg1SiCu, EN AW-6061, DIN 3.3211. 6082: AlSi1MgMn, EN AW-6082, DIN 3.2315. 7075: AlZn5,5MgCu, EN AW-7075, DIN 3.4365. Any of these designations can be used in your enquiry; we will match the correct material.
Why can the invoiced weight differ from the calculated weight?
The calculator gives the theoretical weight. The actual weight varies with dimensional tolerances and cutting allowance; we invoice on the actual weight as weighed.
What information should I send for a quote?
We only need the grade, size (diameter × length), quantity and delivery location. If you fill in the calculator above, these details are added to the WhatsApp message automatically.
