Other Grades of Aluminium

1000 series

The 1000 series of aluminium are the purest forms of all the standard commercial grades. All grades contain at least 99% aluminium., which gives moderate strength but very high maleability. For example grade 1050 has the lowest strength of all commercial aluminiums, and is usually available in the H14 temper, which makes it extremely ductile. 1000 series are commonly used in sheet form for bending and forming applications. All the grades listed below can be anodised, or passivated, for example using the Surtec process, which we also offer.

2000 series

The 2000 series of aluminium are alloys of primarily aluminium and copper. Typically the copper content will be between 2 and 10% The copper increases the alloy's hardness and strength. This material machines well, and is oftne used where strong, hard, high strength is needed, for example in aerospace and precision machine applications.

3000 series

3000 series aluminium's primary alloying element is manganese. The alloys offer good corrosion resistance and moderate strength. The scope of applications for this range is diverse - from kitchen equipment and hardware to heat exchangers. The materials do not machine as well as other grades, such as the 6000 series.

5000 series

Magnesium is the main element used in the composition of the 5000 series of aluminium. The 5000 series grades of aluminium are non heat-treatable alloys. The 5000 series grades also have excellent resistance to corrosion caused by saltwater, for this reason they are often referred to as the Marine Grades of aluminium. It has good weldability properites and can be readily anodised.

6000 series

Alloyed with silicon and magnesium, the 6000 grades of aluminium are very strong and easy to machine to a high finish. 6082 (see common grades above) is the most common grade of commercial aluminium sections and plates, and T6 is the most common temper. 6082T6 is the strongest of the 6000 grade alloys, which is particularly suitable for structural applications and also for welding and machining. Often know simply as 'T6'. Other grades are shown below:

7000 series

Zinc is the largest alloying element in the the 7000 series grades. They are the hardest and strongest commercial grades of aluminium.

Grade 7075 is the most common of the 7000 series grades. It is an extremely high strength alloy; the strongest of all commercial grades of aluminium. In fact, grade 7075 aluminium is stronger than many types of mild steel. However, its corrosion resistance is poor, and will normally need a surface finishing process to be applied before use, e.g. powder coating. As can be imagined this grade of light weight high strength materil is often used in aerospace applications.
