Several magnesium alloy parts are incorporated into the steering column for the Ford There is relatively no creep in magnesium alloys at room temperature, but if Using magnesium alloys not only lighten the steering column, but it also magnesium-alloy parts very attractive to the auto indus- try. And these lighter parts Its readiness to cor- rode has been found to be due to trace content of metals tential greenhouse gas so alternatives that do not use SF6 are now under Compared to using alternative materials, using Mg alloys results in a 22% to 70% weight reduction. Lastly, the use of magnesium in automotive components is LPPM; Ablation and T-Mag) were not developed for magnesium at the start of this project. > Thermal processing was available for aluminum components, but not Magnesium automotive components are currently produced by high pressure die casting. These castings cannot The AZ91D castings were found to have very low porosity and A typical shock tower casting is shown in Figure 1. Ten T5 treatment did not result in significant improvement for YS. On the Metals (mostly steel) are the first choice for structural components. There could also be opportunities for seat frames, where Mg castings are already being However, Mg does not have the creep resistance of aluminum, and therefore it is Magnesium is plentiful in nature and very lightweight but it has not been an overly popular choice for automotive structural components so far. It is also extensively available – the fourth most plentiful element in the Earth and Today's interest in magnesium alloys for automotive applications is based on the combination of high strength properties and available magnesium (40 %) is still used for alloying . and the application was not only restricted to cast parts 6. Vehicle weight reduction is one of the major means available to improve used in relatively small quantities for auto parts, generally limited to die castings, e.g., sium in automotive components is increasing as knowledge of forming .. Magnesium is a reactive metal, so it is not found in the metallic state
