Aluminum alloys are now more important in the automobile industry than ever before.
The government is pressuring the industry to produce cars of high quality and with high fuel efficiency hence care makers are replacing traditional iron-based alloys with aluminum.
Aluminum alloy parts are typically one-third to one-half the weight of those made with steel as a result cars with all aluminum parts use approximately 50% less fuel than those with steel components.
Although most aluminum alloys are soft they can have a higher tensile strength than steel.
Adequate alloy and solution treatment can increase their tensile strength thus resulting in a vehicle with good impact capacity
