Selecting Forged Aluminum for Automotive Applications 840124

With the current and future efforts to downsize automobiles and reduce their weight, strong lightweight materials, in various product forms, are being substituted for many traditionally ferrous components. One of the substitute materials is aluminum, which although itself is not new to automobiles is finding novel applications as forgings in critical chassis and suspension areas. The 1984 Corvette provides an excellent example of how the use of forged aluminum can reduce unsprung and overall weight as well as improve performance without compromising the integrity of the vehicle. Using aluminum as forgings permits taking maximum advantage of its high strength-to-weight ratio, excellent ductility and toughness, and good corrosion resistance. This paper will discuss the various considerations to be entertained when looking at aluminum forgings for automotive applications and the benefits of planning for these lightweight parts early in the design phase.
