Notes:
The potential use of an Al-9Si-1Cu alloy (W328 alloy) as a replacement for W319alloy in engine blocks was investigated.. The ambient mechanical properties (tensile,hardness and fatigue) of sand and permanent mould cast test bars along with bars machinedfrom a sand cast automotive component were studied. The tensile properties were evaluatedin as-cast and T6 heat-treated conditions. The effects of Fe and Mn on properties were alsoinvestigated. The castings in W328 alloy exhibit lower porosity than W319 alloy, which isattributed to the smaller solidification range and feeding distance and larger volume fractionof the eutectic phase. Higher iron levels increased the level of intermetallics and reducedproperties. The addition of Mn did not offset the effect of higher iron levels. The W328 alloyoffers some advantages over the 319 alloy and is a potential candidate for production ofautomotive components such as engine blocks and cylinder heads
