FIELD: hardware production, possibly manufacture of different-profile articles with envelopes of non-ferrous metals and alloys having high consumers' properties. SUBSTANCE: method comprises steps of making composite blank by cladding core with belt or by pressing it around from ingot for subsequent deformation in pass system formed by prefinal and final roll grooved passes. Composite blank is deformed in rolling mode for providing stable and reliable joining of envelope with core. Subsequent deformation in final pass is realized in drawing mode for providing high stability at making shaped product. Spacing between centers of pass forming rolls is normalized. EFFECT: high-strength joining of product components, low thickness difference of envelope, enhanced stability of shaped product. 2 dwg, 1 tbl, 1 ex
