Question

What is the tensile strength of aluminum?

(a) 122.5 GPa

(b) 220 MPa

(c) 70.5 GPa

(d) 45 MPa

The question was posed to me in my homework.

I'm obligated to ask this question of Aluminium and its Alloys, Zinc and its Alloys topic in section Non Ferrous Materials of Engineering Material & Metallurgy

Answer 1

Right choice is (d) 45 MPa

For explanation: Pure aluminum has a low tensile strength of 45 MPa and Young’s modulus of 70.5 GPa. Copper has a tensile strength of 220 MPa and Young’s modulus of 122.5 GPa.
