What are the properties of aluminium?

Aluminium is very low density and, unlike steel, very light. The properties can differ significantly depending on the material composition. This should be considered when processing aluminium. The properties of aluminium include the following:

Corrosion resistance
Due to their oxide layer, pure and ultra-pure aluminium metals in particular are highly resistant to corrosion in environments with neutral pH values. Aluminium reacts less well in the acidic or alkali range.
Good formability
Aluminium is relatively soft. It can be easily plastically deformed and is ideally suited to non-cutting manufacturing processes.
Good machinability
Despite its high strength, aluminium remains quite soft and as such is highly suited to machining. The non-ferrous metal allows high feed speeds and facilitates processing with the tightest tolerances.
Outstanding thermal and electrical conductivity
Aluminium is an excellent conductor of heat and electricity.
Magnetic neutrality
Aluminium materials are not magnetic.
Highly reflective
Bright metal aluminium surfaces reflect light and heat radiation with only slight absorption.

Furthermore, it is possible to change the colour of aluminium surfaces by means of anodising and arbitrary coating methods.
