Aluminum Lightweight Castings-Some Cost-Saving Ideas 770322

Aluminum castings have much to offer the automotive industry in terms of weight reduction and energy savings. Their long-term acceptability can only be assured, however, by applying the most cost-effective combinations of material and processing. This paper will point out some “cost-saving” opportunities in two basic areas: (1) The use of hypereutectic aluminum-silicon alloys to eliminate a need for ferrous wear-surface inserts, to reduce machining capital expenditures and to reduce overall part weight; and (2) The use of two processing methods, “Pore-Free” die casting and “low-pressure” casting, to produce aluminum parts with minimum metal usage and energy consumption.
