Mechanical Properties of Aluminum Sand Castings

Cast Aluminum Alloys These are used for parts of complex shapes by sand casting, permanent mold casting, and die casting. The compositions and minimum mechanical properties of some cast aluminum alloys are given inin the table below. Castings generally exhibit more variation in strength and less ductility than wrought products. Tolerances, draft requirements, heat treatments, and quality standards are given in the Aluminum Association ‘‘Standards for Aluminum Sand and Permanent Mold Castings.’’ Tolerances and the level of quality and frequency of inspection must be specified by the user if desired.

Values represent properties obtained from separately cast test bars. Average properties of specimens cut from castings shall not be less than 75% of tensile and yield strength values and shall not be less than 25% of elongation values given above.

* Mechanical properties for these alloys depend on casting process. Consult individual foundries.
