Ultrasonic attenuation properties of two kinds of pored Al alloy were studied between1MHz and 10MHz.. The results show that the ultrasonic attenuation properties are determined bythe pore structures of Al alloy. Ultrasonic attenuation coefficient α in porous Al alloy increaseswith decreasing of pore diameter d, decreasing of porosity Ps , and increasing of specific surfacearea Sv. However the α in cellular Al alloy increases with decreasing pore diameter d, increasingporosity Ps and increasing specific surface area Sv. Ultrasonic attenuation property of cellular Alalloy is better than that of porous Al alloy when they have the similar pore diameter d andporosity Ps. The origin for different attenuation properties is discussed in these materials
