Rio Tinto 319.2 is a heat-treatable, Al-Si-Cu casting alloy (3xx.x series). It is available in the form of ingots for remelting, for the production of sand and permanent mold castings. Alloy 319.0 exhibits very good castability and pressure tightness, moderate strength, and good high-temperature properties. It offers good strength in the as-cast condition and is often used that way. However, it is possible to increase strength considerably by heat treatment. In applications that experience high temperatures, as in engine components, it is common to employ a T5, T7, or O treatment. These treatments tend to stabilize the casting and reduced dimensional changes in the component caused by high temperatures in service.
