Properties of Al Alloy A-356


Q. Sir,

I am doing a project on "Analysis of Aluminium Alloy Wheels". I would like to know the properties of Aluminium Alloy A-356 especially Young's Modulus, Ultimate Stress, Density and Poisson's Ratio.

- Vellore, Tamilnadu, India


A. Properties for Aluminum A356.0-T6, Sand Cast*

Density 2.67 g/cc 0.0965 lb/in
Tensile Strength, Ultimate 234 MPa 33900 psi
Tensile Strength, Yield 165 MPa 23900 psi 0.2% offset
Elongation at Break 3.5 % 3.5 % in 50 mm
Modulus of Elasticity 72.4 GPa 10500 ksi (Tension)
Poisson's Ratio 0.33 0.33

*Tensile strength and elongation values are slightly higher for Aluminum A356.0-T61, Permanent Mold Cast. Data from
