Pure aluminum is a poor casting material. Almost all aluminum castings are made of an alloy of aluminum. There are more than 50 different aluminum alloys used for sand castings. The typical properties and characteristics of the most common are shown below.

Heat Treat
For many applications, aluminum alloy castings must be heat treated to obtain the mechanical and physical properties that are required for the intended structural performance in service. Heat treatments increase the castings' strength, hardness, toughness, and impact resistance. Furthermore, heat treatments improve the castings' Machinability and minimize dimensional changes that occur at elevated service temperatures from metallurgical instability, which is encountered in the as-cast condition.

Shown below are the improved mechanical properties of 319, 355, and 356 after heat-treatment.
