Aluminium

Aluminium is the most abundant metallic element in the Earth's crust, where it accounts for 8% of its composition by mass. It is usually found in its chief ore, Bauxite, from which it is reduced to Alumina by the Bayer Process, and then further refined to Aluminium metal by the Hall-Héroult Process to 99% purity.

Once refined, it enjoys many characteristics useful to the engineering industry, namely: low density, excellent resistance to corrosion, a high strength-to-weight-ratio, high thermal & electrical conductivity, easy formability, and ready alloying properties to enhance existing strengths and to add yet more.

It is used across the engineering spectrum in countless applications, not least in aviation where it has been in continuous use since the Wright Flier, as well as in the automotive, marine, energy and leisure and recreation sectors.

Integ Metals supply all grades of aluminium, in all common shapes and forms, so please contact us with your direct requirements or peruse these pages for guidance.

 

Aluminium Grades

256_edited_edited.jpg

Grade 1xxx Series Aluminium Alloys are categorised as commercially pure and unalloyed, with a minimum 90% Aluminium content.

As a pure material, aluminium is ductile, easy to shape, easy to...

The principle alloying element of 4xxx Series Aluminium Alloys is Silicon. Silicon is used to lower the melting range of Aluminium, whilst retaining sufficient structural integrity to prevent brittleness. As such, they are predominately used to manufacture...

airplane-before-take-off-on-runway-BES3G

The principle alloying element of 7xxx Series Aluminium Alloys is Zinc. With the addition of other alloying elements, such as Magnesium, 7xxx Series Alloys are the strongest of all Aluminium alloys...

2XXX Header.png

The predominent alloying element of 2xxx Series Aluminium Alloys is Copper, making up up to 6.8% of their composition. Copper has a significant effect in increasing Aluminium's strength, whilst Magnesium, Manganese and Silicon additions allow the...

5xxx_Header_edited_edited.jpg

The primary alloying element of 5xxx Series Aluminium Alloys is Magnesium, which helps to create moderate to high-strength alloys, with the highest strength of all non-heat-treatable alloys. For applications where temperatures exceed 65℃...

8xxx_Header

The 8xxx Series of Aluminium Alloys is reserved for alloys of miscellaneous elements. Chiefly, these are Lithium, Tin and Iron. Alloys in this series are usually created to meet specific purposes, and, therefore, the aforementioned alloying elements...

Aramids in Construction

3xxx Series Aluminium Alloys feature Manganese as their main alloying element. The actual Manganese content is limited to around 1.8%, but even this small addition is enough to give these alloys a 20% strength increase over 1xxx Series Alloys...

6xxx_Header_edited.jpg

Magnesium and Silicon are the two primary alloying elements of 6xxx Series Aluminium. In tandem, the two elements create a compound within these alloys termed “Magnesium Silicide” (Mg₂Si), which allows this series of alloys to be heat treated for...
