ALUMINIUM ALLOYS - YIELD STRENGTH AND TENSILE STRENGTH


Aluminum yield strength, tensile strength and ductility values at room temperature are given in the following aluminum strength chart. Aluminum has typical tensile strength between 40 MPa to 700 MPa. The mechanical strength of aluminum can be increased by cold working and alloying. Copper, magnesium, silicon, manganese and zinc are used as alloying elements. Aluminum doesn't become brittle at low temperatures and retains its ductility.

Typical room temperature yield strength, tensile strength and ductility values for some of the aluminum alloys are given in the following chart.
