Twenty-eight days uniaxial compressive strength and elastic modulus ranged from 42.3 to 55.8 MPa and 22.4 and 28.6 MPa, respectively.

A6063 alloy is a standard material that is lightweight yet has excellent strength. As a result, it is used in the construction of ships and boats. Conversely, its strength is lower than that of steel, so an enhancement of strength is required. Manganese element was added to the AA6063 alloy to enhance its tensile strength.
