Aluminum-silicon (Al-Si) alloys have good castability in combination with high corrosion resistance, thermal conductivity, and specific strength, making them a strong candidate for many automotive applications. This article describes the processes used in the production of die-cast AlSi9Mg engine brackets for Volvo trucks, the effects of solution treatment temperature on Si particle size, and the benefits of Mg additions on yield strength and heat treatability.
