Development of Lightweight Oil Pans Made of a Heat-Resistant Magnesium Alloy

Article of Honda R&D Technical Review Vol.12 No.1


A new heat-resistant magnesium alloy (hereafter referred to as “ACM522”) for die-casting based on the Mg-Al-Ca-RE system has been developed. In the 150°C temperature range, ACM522 yields high creep characteristics which are superior to the conventional AE42 heat-resistant magnesium alloy for die casting. Further it exhibits an excellent resistance to both heat and corrosion which is equivalent to ADC12 general-purpose aluminum alloy. Use of magnesium for oil pans has raised a number of problems such as axial force drop in the bolted areas and, until now, oil pans made of magnesium had not been applied to mass-produced automobiles. The authors applied the ACM522 for oil pans and achieved a 35% weight reduction compared to conventional oil pans made of aluminum.
