FIELD: powder metallurgy. SUBSTANCE: burden contains, wt.%: iron scale, 39-42; silicon oxide, 41-43; ferrosilicon, 1-5; aluminum, the balance. Products manufactured from porous permeable material based on burden of such composition possess increased strength and, accordingly, improved resistance to dynamic and static loads. Among products manufactured from said material are filtering members, fire shields, aerators and other porous articles. EFFECT: reduced metal usage, wider range of uses, and availability of basic components. 1 tbl
