POROUS ALUMINUM COMPOSITE MATERIAL AND ITS PRODUCTION METHOD

Title:

POROUS ALUMINUM COMPOSITE MATERIAL AND ITS PRODUCTION METHOD

Document Type and Number:

Japanese Patent JP2007238971

Kind Code:

A

Abstract:

To provide a foamed aluminum material in which coarse foams are not contained, and pore sizes are controlled, by solving the problem that, in the conventional production method for foamed aluminum where a foaming agent is added to the molten metal of an aluminum alloy, the generated foams are flocculated to form coarse foams to cause deterioration in the strength of a member.

Relating to the porous aluminum composite material, pore sizes are ≤500 μm, also, the porosity of closed pores is 40 to 80%, and the absorption amount of compressive energy is ≥1 MJ/m3.
