Can aluminum alloys be cast?

Yes, aluminum alloys can be cast and are among the most widely cast non-ferrous metals worldwide. Common casting processes include die casting, gravity casting, sand casting, low-pressure casting, and investment casting. Aluminum casting offers high strength-to-weight ratio, good corrosion resistance, and excellent dimensional stability. Annual global aluminum casting production exceeds 100 million metric tons, covering automotive, electronics, machinery, and aerospace industries.
