Summary

IS 636 specifies non-ferrous alloy ingots for sand casting, covering aluminium, copper, and zinc alloys. It defines chemical composition requirements for each grade. Foundries purchasing casting ingots reference this standard for incoming material quality.

Specification for non-ferrous metal and alloy ingots (aluminium, copper, zinc, and their alloys) for sand casting, covering grades, chemical composition, and sampling.

Practical Notes
! Always check ingot chemical analysis against IS 636 grade requirements before melting.
! Aluminium-silicon alloys (LM6, LM25 equivalent) are the most common casting alloys specified under IS 636.
! For pressure-tight castings (valve bodies, pump housings), verify porosity requirements in addition to IS 636 chemistry.
