Description

The alloy D16 is used: for the production of power subassemblies of aircraft, car bodies, pipes, operating at temperatures up to +230 °C; hot-pressed drill pipes with variable cross-sections; profiles with cross-sectional area of 200 cm2 and a diameter of circumcircle up to 350mm suitable for use in the aviation industry and special branches of engineering; round, rolled and drawn pipes for pipes transmission shafts and the linkage control planes; moulded panels of constant cross section with longitudinal fins in the aircraft industry, made sweep of extruded finned tubes in the plane of the width of the fabric up to 2100 mm; large extruded pipes.

Note

ISO 209−1 D16 alloy is designated АlCuMg1 and 2024, alloy D16ch — 2124.
