What is Young’s modulus of 6061 aluminum?

Typical average Young’s modulus for 6061 is about 69 GPa (≈ 10.0 × 10^6 psi). Compression modulus is roughly 2% higher than tension modulus.

How do tension and compression moduli differ for aluminum?

Compression modulus is typically about 2% higher than tension modulus. Values shown here are the average of tension and compression.

Can I convert GPa to psi?

Yes. 1 GPa ≈ 0.14504 × 10^6 psi. The on-page calculator lets you view values in GPa or in millions of psi.
