Aluminium is available in both wrought and cast forms.The wrought forms comprise hot and cold rolled sheet, plate, rod, wire and foil. The ductility and workability of aluminium mean that extrusion is a simple method of producing complex shapes, particularly for long, structural members such as I and H beams, angles, channels,T-sections, pipes and tubes. Forging, both hot and cold, is used extensively as a fast, economical method of producing simple shapes. Precision forging is particularly suitable for aluminium
alloys, giving advantages of good surface finish, close tolerances, optimum grain flow and the elimination of machining.

The four most commonly used methods of casting are sand casting, lost wax casting, permanent steel mould casting and die-casting. The requirement for high fluidity in a casting alloy means that many are based on aluminium–silicon alloys although heat-treatable (age-hardening) alloys are often used for sand, lost wax and permanent mould castings. Lost wax and die-casting give products with smooth surfaces to close tolerances and are processes used extensively for aerospace products.

In order to effect a weld the components to be joined are heated to a high
temperature, in the case of fusion welding above the melting point of the
parent metals, and brought together to enable the components to coalesce.
The heat of the welding operation is conducted into the parent metal such
that in any welded joint there are three distinct areas – the weld metal in
a fusion welded joint, the HAZ in the parent material and the unaffected
parent metal. The HAZ may be further subdivided into areas with particular
properties depending upon the alloy system involved. Since the HAZ
will have experienced one or more cycles of heating and cooling the properties
may be radically different from those of the unaffected parent metal.
This is particularly the case with those aluminium alloys that have been
strengthened by either cold working or precipitation hardening. One aspect
of this is the width of the HAZ, a function of the high thermal conductivity
of aluminium and the consequent size of the area where there has been
a substantial loss of strength. Only when the alloy is in the as-cast or annealed
condition will the properties of the HAZ match those of the parent metal.

Aluminium alloys may be divided into two broad classes, cast and wrought
products.These two classes can be further subdivided into families of alloys
based on chemical composition and finally on temper designation. Temper
designations are used to identify the condition of the alloy, in other words
the amount of cold work the alloy has undergone or its heat treatment condition.
There are a number of schemes available for identification of the
alloy and its condition. In this book the numeric method adopted by the
European Committee for Standardisation (CEN) will be used as standard.
This system uses four digits to identify the wrought alloys and five digits
to identify the cast alloys, and is broadly the same as the ISO and US numerical
methods of identification where a four digit number identifies the
unique alloy composition. This is in agreement with the recommendation
made in the early 1970s for an International Designation System issued by
the Aluminum Association in the USA. The chemical composition limits
specified in the CEN specifications are identical with those registered with
the Aluminum Association for the equivalent alloys. This should simplify
the sourcing of alloys and remove the confusion that can surround the identification
of specific grades. One perennial problem for the welding engineer
is the use of superseded specification designations to identify alloy
