GOST 21 488−97 regulates the production of square of duralumin high-normal and high precision. The most commonly used alloy D16. The composition of the normalized GOST 4784−97. Control of structure — GOST 24 231−80. Hot-pressed duralumin square without heat treatment is not further marked. Hardened and naturally aged square is denoted by a — T Annealing with normal plating is indicated additionally A. M. — Hardened and naturally aged square with normal plating — A. T. Thicker plating is marked, the Microstructure of semi-finished products after heat treatment must not have signs of burnout. At the end of processing the sheet being tested.
Duralumin square has light weight, high specific strength, easy processing, plastic, well welded together by spot welding. Corrosion resistance increases after cladding of pure aluminum. Used for hardening tempering and aging. Cold deformation gives the material hardness. Annealing increases the ductility, facilitates the processing of material by cutting.
Due to the high specific strength, duralumin square is used in the design of high-speed transport: trains, ships, transport aircraft, building structures. These squares are relevant in the construction, engineering, fuel and energy.
