8
– Good mechanical strength properties
Strength ranging from 60 to over
500 N/mm
2
– Good resistance to atmospheric and
saltwater corrosion
– Good plasticity properties
– Very well suited to MIG/TIG welding and
beam welding (e.g. laser welding).
MIG = metal inert gas welding
TIG = tungsten inert gas welding
Inert gas = protection gas
Properties
Advantages of aluminium
– Aluminium has only about 1/3 of the
specific weight of steel.
– It reacts with the oxygen in the air form a
thin layer of oxide, which constantly
regenerates and protects against further
destruction of the material.
– Aluminium alloys are easy to reuse and
recycle.
– The recycling of aluminium only requires
5 % of the energy expenditure for primary
aluminium production.
– It can be recycled several times.
– The material is non-toxic.
