Aluminium Bar - Aluminium Bar Stock and Alloy Selection Guide from Metalweb


Metalweb is a leading UK aluminium stockholder and aims to provide a 100% on-time delivery and quality product both for day-to-day requirements and long term contracts. We carry out four key roles in the supply chain that help our customers to perform more cost-effectively:

        we hold stock

        we carry out first stage processing

        we have no minimum quantity

        we maintain traceability

To help achieve these roles Metalweb has one of the largest ranges of aluminium products in all alloys (including plate, sheet, bar, tube and other extruded products) carried in stock. This means we can often provide 24 hour delivery with fully certified material when required.

        Flat bar from 9.5mm x 6.35mm up to 152.4mm x 127mm

        Both metric and imperial sizes offered

        Standard alloys stocked including 2011, 2014, 6063, 6082 and 7075

        Specialist alloys stocked including 2024, 2618, 5083 and 6061

Aluminium Bar Selection Guide

The choice of aluminium bar alloy is determined by what the rod or bar will be used for and how it will be machined or finished. Then you can quickly compare your application requirement with the commonly available alloys. You will find below useful descriptions of what each aluminium alloy can do. 

Aluminium Alloy 1050

Aluminium 1050 is a soft workable alloy having high purity which gives excellent corrosion resistance.

Aluminium Alloy 2011

Aluminium 2011, or the Free Machining Alloy, machines to an excellent finish. It often replaces free machining brass without a change of tooling. It is the first choice for screw machined parts unless higher strength or more corrosion resistance is required. Aluminium 2011 contains lead and bismuth consequently losing popularity to alternatives.

Aluminium Alloy 2014

Aluminium Alloy 2014 has a tendency to allow the removal of a greater volume of metal in a single operation for an equivalent standard of finish than 6082. Durability, however, is lower and it needs a protective coating. Aluminium 2014 machines better in solution treated condition than fully heat treated. It is used for machined parts where these characteristics are critical. It is the most common aerospace extrusion alloy.

Aluminium Alloy 3003/3103

Aluminium Alloy 3003/3103 is a 1% Mag Alloy. Usually stocked in solid bar from rather than shapes. It is a good welding alloy often used in cryogenic applications.

Aluminium Alloy 5056A/5083/5251

5056A/5083/5251 aluminium Alloys are alloys in which magnesium is the main alloying element. They are ductile in the soft condition but work harden rapidly becoming extremely tough. The exhibit very good weldability and high resistance to marine atmospheres making them ideal for shipbuilding and road transport applications. They are harder to extrude than other alloys and therefore require longer lead times and higher prices. Not generally stocked, but Metalweb carry a comprehensive range.

Aluminium Alloy 6061

Aluminium Alloy 6061 is the standard structural alloy. It can be easily welded or brazed with fine finishing characteristics and exhibits good corrosion resistance. It is similar to 6082 with better formability but more difficult to extrude and possessing lower strength. It is used for couplings, hardware, hydraulic pistons, etc.

Aluminium Alloy 6082

Aluminium Alloy 6082 is the most versatile of all the medium strength alloys with good mechanical properties, corrosion resistance, weldability and machinability. It is the most common commercial rod and bar alloy from stock. Metalweb plc has the largest range available.

Aluminium Alloy 7075

Aluminium Alloy 7075 is the highest strength bar normally stocked. Not a standard screw machine grade yet produces curled or easily broken chips with good to excellent machined finish. It has a high hardness but poor corrosion and welding characteristics. It is used for machined parts requiring high strength. Mainly used in the aerospace industry, it is available in rounds and rectangles.
