Abstract
As world’s sustainability become the most influential topic, aluminum and its alloys are becoming the preferred material of the automotive industry because they allow vehicle weight to be reduced without compromising safety. Thus, aluminum has taken its place in the global industry as an alternative material that can be used instead of steel. The main drawback of forming aluminum at room temperature is galling. This phenomena in cold forming of aluminum not only affect the quality of the produced parts but also the lifespan of production tools. This paper reviews the galling of aluminum alloys during bulk and sheet cold forming processes along with friction conditions. The available testing methods in order to simulate the actual cold forming process are introduced. Effect of process parameters such as lubrication, tool surface finish and tool coatings are discussed in detail.
