• Both metric and imperial sizes offered
• Standard alloys stocked including 1050, 2014, 3103, 5083, 5251, 6082 and 7075
• Specialist alloys stocked including 2024, 5005 and 6061
• A range of patterned sheet and treadplate
• For products more than 6mm thick - we classify this as plate, so please refer to our plate section.
Aluminium and Processing and Cutting Capabilities
Metalweb has a range of processing & cutting capabiltiies in order to provide you with the size you need. A large number of our customers look to us to carry out their first stage processing for them as this means they can focus on their area of expertise in more skilled machining and equipment manufacture.
Aluminium Sheet Selection Guide
The selection of aluminium sheet alloy is determined by what the sheet or strip will be used for, how severely it will be formed and what the welding requirements are. Then you can quickly match your application needs with the properties of the commonly available aluminium alloys. You will find below useful descriptions of what each of the alloys can do.
Non-Heat Treatable alloys
Aluminium Alloy 1050/1080/1200
Aluminium alloy 1050/1080/1200 are commercially pure aluminium, highly resistant to chemical attack and weathering. They are easily worked and welded, but the lowest strength aluminium. They are also excellent for chemical processing equipment and other uses where product purity is important, and for metal pressings of all types where ductility is critical. The comprise the widest range of sheet from stock.
Aluminium Alloy 1350
Aluminium alloy 1350, or the electrical quality alloy is not often found in the rolled form. It is normally rolled to special requirements.
Aluminium Alloy 3003/3103
Aluminium alloy 3003/3103 is stronger than 1200 with same good formability. It displays fine corrosion resistance and weldability. It is typically used for storage tanks, chemical equipment, brazing applications, van bodies and cryogenic uses. For higher strength, consider 5251 or 5052.
Aluminium Alloy 5005
Aluminium alloy 5005 is specified for anodised applications to match with 6063 extrusions. Anodised coatings are clearer and lighter than for 3003/3103 in severe drawing applications. Aluminium 5005 finds uses are decorative, architectural and consumer products.
Aluminium Alloy 5052/5251/5754
Aluminium alloy 5052/5251/5754 forms readily in the intermediate tempers. Its’ corrosion resistance is very good as is weldability. It displays better salt water corrosion resistance than 1200. Typical applications include pressure vessels, tanks, fittings or applications involving forming or welding where strength higher than 3003 is needed, including houseboat hulls, pontoon boats and van bodies. 5052 (2.5% Mag) is commonly used in the USA; 5251 (2% Mag) is largely a 'UK only' standard; whereas 5754 (3% Mag) is the European standard in this range.
Aluminium Alloy 5083
Aluminium alloy 5083 is stronger than either of the above alloys. It is used for high strength welded applications with outstanding joint strength – rail wagons, marine components, bridges, stationary cryogenic vessels and overhead cranes. It possesses excellent weldability and corrosion resistance. Static welded strength is second only to 5754 and 5083 is superior to 5754 in energy absorption. It is however restricted to temperatures below 150ºF = 65.5ºC.
Aluminium Alloy 5086
Aluminium alloy 5086 is excellent for welded structures – ship hulls and superstructures, road tankers, pressure vessels, movable and stationary cryogenic vessels and structures requiring a high rate of energy absorption. It is however restricted to temperatures below 150º F = 65.5ºC. It is also more commonly used in the USA.
Aluminium Alloy 5154
Aluminium alloy 5154 is similar to 5083 which has largely superseded it. Mainly used on MOD and naval applications.
Aluminium Alloy 5454
Aluminium Alloy 5454 is used for all types of welded structures. ASME Code approved for temperatures up to 400º F = 204.4ºC. It is used for hot asphalt road tankers, dump bodies, pressure vessels and marine structures.
Heat Treatable Aluminium Alloys
Aluminium Alloy 2104/2024
Aluminium alloys 2014/2024 are high strength alloys with excellent machinability widely used in aircraft. They have limited formability and only fair corrosion resistance in the heat treated condition. They are not recommended for fusion welding. Typical applications include high strength parts in aircraft and machinery, including gears and bolts and for security vans where strength is critical.
Aluminium Alloy 6082/6061
Aluminium alloy 6082/6061 is a widely used structural alloys for light to medium strength applications. They combine good formability, weldability, corrosion resistance and strength after heat treatment. Since they lose appreciable strength when welded, the 5000 series alloys replace them in some marine applications. Availability of bars, shapes, tubing and pipe in the same alloy helps make this a popular selection. 6082 is the most common heat treated plate from stock. 6061 is more commonly used in the USA.
Aluminium Alloy 7020
Aluminium alloy 7020 is a good machining quality alloy mainly used on the continent instead of 6082.
Aluminium Alloy 7075
Aluminium alloy 7075 is a very high strength aircraft alloy. Properties include good machinability and hardness. It is not recommended for welding or corrosion resistance.
