Globally, there are increasing efforts to reduce the weight of automobiles, increasing fuel efficiency which aids in the reduction of emissions. Various grades of steel have been the predominant material used for manufacturing automobiles chassis' and body. A new generation of advanced high-strength steels (AHSS) are being developed and produced to maintain the automotive industry’s demand for steel.
Automotive manufacturers are now also working with aluminum producers to increase the percentage of aluminum used in the production of automobiles. Aluminum offers low density, excellent formability, corrosion resistance, and high strength.
