The work aims to study the effects of basis materials and loading rate on the mechanical behavior and energy absorption of Al lattice truss. The compressive mechanics of Al lattice truss with industrial pure aluminum and 6063 aluminum alloys as basis materials were tested at three different loading rates. When the loading rate increased from 2 mm/min to 250 mm/min, the yield strength of the pure Al lattice truss increased by 2 MPa, and the yield strength of the 6063 aluminum alloys based lattice truss increased by 7.6 MPa. When the loading rate increased from 250 mm/min to 500 mm/min, the yield strength of the pure Al lattice truss remained constant; however, the yield strength of the 6063 aluminum alloys based lattice truss increased by 8.2 MPa. At the same loading rate, the yield strength of 6063 aluminum alloys based lattice truss was higher than that of pure Al lattice truss. The mechanical properties and energy absorption per unit volume of 6063 aluminum alloys based lattice truss increase with the increase of loading rate, and the mechanical properties and energy absorption of 6063 aluminum alloys based lattice truss are much higher than those of pure Al lattice truss.
