Metallurgical recommendations regarding the design of aluminum pressure castings and their molds.

There are important metallurgical differences between aluminum casting alloys which must be taken into account in casting and mold design. These differences are noted in the case of casting alloys with a wide solidification range and a typical cooling curve, alloys with a large isothermal solidification range, alloys with a high silicon content, alloys with a high latent heat content, and a hyperentectic silicon-containing alloy.
