Aluminium Flat Bar
Aluminium flat bar (rectangular bar) for flat parts produced by milling and CNC machining, busbars and structural members. We cut pieces to the length you need, in any quantity.
Grades and sizes
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.
Flat bar standard: EN 755-2 · tolerances EN 755-5
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.

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.

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
What are the designations for 5083, 6061, 6082 and 7075?
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 (thickness × width × length), quantity and delivery location. If you fill in the calculator above, these details are added to the WhatsApp message automatically.
