For high strengthen applications, casting foundries in India use alloys, which also require for good ductility. It improves desirable mechanical properties when treated with barium.

1. Casting foundries in India use alloys for high strength
Applications that also require good ductility.
These alloys, when treated with small amount of barium,
may Improve desirable mechanical properties : light weight
and high strength.
Such alloys, containing interdendritic eutectic
microstructure, may offer engineers strength and ductility
not currently seen in existing cast alloys.
These alloys also may be further strengthened by heat
treatment.
