Three different aluminum alloy wires, drawn to their drawing limit by using conventional drawing and cryogenic wiredrawing, showed that the latter method produced results with superior mechanical properties due to the use of lubricant in this process. Aluminum has become the material of choice for lightweight design. In recent years, medium strength A5xxx and A6xxx-series alloys have been widely used in automotive sheet components, substituting conventional steel because of their superior strength to density ratios. Using these alloys results in a reasonable ratio of cost-per-weight saving and a good compatibility with existing production techniques in terms of forming. Extensive research on formability is required to develop useful components of complex shapes out of this material.
