The automobile sector consumes enormous amounts of ferrous and non-ferrous materials. Since the first models manufactured, several alloys have been used to improve resistance to oxidation or corrosion. The aluminum sheet and foil tape are highly sought from this area, after a transition period iron to lighter materials.
Aluminum As An Ally To Reduce Weight
The reduction of the pressure is the most striking in the evolution of the construction of automobiles in the last decades. The oil crisis of the 70s and the awareness of the environment generated this gradual change. Also the increase of the security, the changes in the production and the necessity to recycle a greater quantity of material influenced in it.
It must be borne in mind that a large part of the ferrous material is found in the engine and the transmission. Its replacement by aluminum and resins allowed to significantly lighten the weight of the cars in the 90s to 40%.
Subsequently, it has been used in combination with other lightweight materials, such as carbon fiber or magnesium. This has involved specific complications, so it has been necessary to develop new technologies for manufacturing processes.
