After three years of commercial application of low iron pressure die casting alloys for structural parts, this paper reviews industrial scale experience and looks out to further potential in alloy development. Silafont-36TM (AA 365) and Magsimal-59TM both have an iron content below 0.13 wt% ensuring good ductility of the casting while completely avoiding soldering or sticking to the die in manufacturing. This is a breakthrough in pressure die casting where during decades the soldering problem has prevented the application of ductile casting alloys. Silafont-36TM and Magsimal-59TM are used for suspension parts, steering wheels, space frame nodes, motor mounts etc. High pressure die casting and squeeze-casting are the processes applied. Silafont-36TM is an AlSi9Mg-type alloy that can be heat treated and welded. Magsimal-59TM is of the AlMgMnSi-type and specially designed for applications without heat treatment with extraordinary mechanical and dynamic properties. This paper describes the manufacture of the castings, the application and component properties for both alloys.
