The specific stiffness and impact energy absorption capacity of foam metals are among the important uses of foam metals. A large range of modulus of elasticity can be obtained through the selection of foam metal parameters, so that the desired response frequency can be matched and harmful adverse vibrations can be suppressed and eliminated. Typical applications of energy absorption are buffers and shock absorbers. The materials are also widely used in bumpers for automobiles, buffers for lift and transport systems, energy-absorbing linings for machinery, etc.
