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

: These alloys naturally form a protective oxide layer, providing high resistance to environmental degradation. Major Casting Processes

: 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,...

Different processes are selected based on the required part complexity, production volume, and desired mechanical properties. : These alloys naturally form a protective oxide

: 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 . alloying it with elements like silicon

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