What is the order of elastic modulus for Nickel alloys, Lead alloys, Molybdenum alloys, alumina? Correct Answer Pb < Ni < Mo < Al2O3

Lowest elastic modulus is of Lead and its alloys of 14-18 GPa. Ni and Mo alloys have elastic modulus of 180-214 and 330-360 GPa respectively. Al2O3 has highest E among the four of 415 GPa.
