Description of aluminium

Aluminium is a non-ferrous material. It has a low density and is a good thermal and electrical conductor. Aluminium is also a material which is easy to work. Its lightness makes it a preferential material: it has a very good density/mechanical performance ratio. Finally, aluminium can be recycled completely and infinitely, facilitating eco-design.

Applications for aluminium

• Industrial structures: rods, bars, plates, profiles, machine parts, etc.
• Electronic accessories
• General mechanics
• Motor vehicles
• Energy
• Rail
• Aeronautics
• Construction

Benefits of aluminium (depending on grade)

• Very resistant to corrosion (depending on alloy and surface treatment)
• Good thermal and electrical conductor
• Low density
• Very good weight/performance ratio
• Easily machinable
• Weldable
• Cold transformable
• Castable
• Long lifetime
• Recyclable
  

Families of aluminium alloys

NON-ALLOY ALUMINIUM

• 1000 series

Alloys in the 1000 series consist of aluminium which is 99% pure or higher. This series has very good plastic deformation properties, and excellent characteristics with regard to chemical agents and different atmospheres. It also has good welding, brazing and anodisation properties, and relatively low mechanical resistance. The properties depend mainly on the quantity of impurities and the level of strain hardening or softening (annealing or recovery).

THERMOSETTING ALLOYS

• 2000 series

In the 2000 series copper is used as the main alloy element and enables traction resistance to be increased using solution heat treatment. These alloys have an average mechanical resistance which depends on the heat treatment (T6 recommended). They have good heat resistance but poor welding properties and relatively low corrosion resistance in corrosive atmospheres.

The most commonly used grades are 2017, 2011 and 2030.

• 6000 series

The alloys in this series contain silicon and magnesium. They have very good properties for hot deformation by lamination, and above all by extrusion and swaging and cold forming. They have very good corrosion resistance and good welding properties. Conversely, heat resistance is limited.

Grades 6060 and 6082 are the most commonly used ones.

• 7000 series

The alloys in this series contain silicon and magnesium. They have very good properties for hot deformation by lamination, and above all by extrusion and swaging and cold forming. They have very good corrosion resistance and good welding properties. Conversely, heat resistance is limited. Grades 6060 and 6082 are the most commonly used ones.

The most commonly used grade is 7075 (FORTAL).

NON-THERMOSETTING ALLOYS

• 3000 series

Manganese is the main alloy element in this series, often with a small quantity of magnesium. However, only a small percentage of manganese can be added effectively to aluminium, i.e. 1.0% to 1.5%.

• 4000 series

The 4000 series is a special case, since it is both heat treatable and not heat treatable. Alloys in the 4000 series are combined with silicon, which can be added in sufficient quantities to reduce the melting point of aluminium, without affecting its fragility.

• 5000 series

Magnesium is the main alloy agent of the 5000 series, and is one of the most effective alloy elements, and one of the most commonly used for aluminium. Alloys in this series have good mechanical resistance, and effective weldability. They also have high corrosion resistance in marine environments. For this reason, aluminium and magnesium alloys are widely used in structural applications. The most commonly used grades are 5083 and 5754.
