1)Density (specific weight) is the amount of mass in a unit volume.
2)It is measured in kilograms per cubic metre. Aluminium alloys, with typical densities around 2800 kg/m3 are considerably less dense than steels.
3)Aluminium-2800 kg/m3
water is 1000 kg/m3
steels-7800 kg/m3
4)Stiffness (rigidity) is a measure of the resistance to deformation such as stretching or bending.
5)The Young modulus is a measure of the resistance to simple stretching or compression.
6)Strength is the force per unit area (stress) that a material can support without failing.
