Aluminum Alloy Castings: Properties, Processes,... May 2026

The performance of an aluminum casting is determined by its alloy composition and the casting method used.

: Aluminum alloys feature a low melting point (approx. 660°C) and high fluidity , which allows them to fill intricate mold details and thin sections easily. Aluminum Alloy Castings: Properties, Processes,...

: While pure aluminum is soft (tensile strength ~90 MPa), alloying it with elements like silicon, copper, or magnesium can increase its strength to over 700 MPa . The performance of an aluminum casting is determined

: These alloys naturally form a protective oxide layer, providing high resistance to environmental degradation. Major Casting Processes alloying it with elements like silicon

Different processes are selected based on the required part complexity, production volume, and desired mechanical properties.
