Aluminum alloy specimens cast by vertical pressure diecasting have higher mechanical strength than that in the specimens by conventional pressure diecasting process. In cast specimens produced by vertical pressure diecasting process, which have thick section and machined surface, the lowering of the strength is not serious in comparison with that in the specimens having thin section and as-cast surface. Tensile strength of cast specimens is good correlation with their specific gravity. The coarse primary crystals formed at low casting temperature have an negative influence on the mechanical strength.
