According to my suggestion,
The question talks about the mechanical property of white cast iron.
Therefore some mechanical properties of wcl are:.
No ductility.
Extremely hard and brittle.
Excellent wear resistant.
Abrasion resistant.
High compressive stress and.
Low tensile strength.

Cast iron contains graphite flakes (sheets) means it contain carbon & is brittle in nature, so cast iron is brittle & brittle materials show low strength in tension than in compression.
