Right option is (b) False

Explanation: Titanium is a low density material which is approximately 60% of the density of steel. It is mainly strengthened by alloying and deformation methods. It is a nonmagnetic metal which has low thermal conductivity. Its coefficient of thermal expansion is generally less than that of steel and less than half that of aluminium.
