Introduction Metal foams are relatively new, highly porous materials that uniquely combine mechanical properties of their phases.
These materials also feature combination of high ability of deformation energy absorption together with very low specific weights and thus high specific stiffness.
Materials and methods Alporas is compounded by pure aluminium that is during foam production process thickened by addition of 1.5 % Ca and stirred by addition of 1.6 % Ti.
