FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy field, particularly to receiving of composition constructional materials on the basis of aluminium. Constructional material allows porous internal structure, formed by ordered system of rectilinear continuous and non-intersecting pinholes with specific surface area of pores 0.005÷10 m2/g. Lateral dimensions of channel are in limits from 0.1 up to 200 micrometre, its inner surface is coated by film of aluminium oxide.
EFFECT: material allows durability, commensurable to durability of monolithic materials, at less density, and also provides ability of management of materials properties.
