Description

Alloy D19 is used: for the production of power subassemblies of aircraft, car bodies, pipes, operating at temperatures up to +200−250 °C; profile hire for use in the aviation industry and special machine building industries; moulded panels of constant cross section with longitudinal fins in the aircraft industry, is made by a sweep of extruded finned tubes in the plane of the width of the fabric up to 2100 mm.
