Description

Alloy АМг61 used: for the manufacture of extruded profiles; replacerange and clad plates with technological plating B (1561Б); parts operating in the temperature range from -196 °C to +70 °C in difficult corrosion conditions (sea water); details of high-speed ships with hydrofoils and hovercraft; welding wire Svamg61; 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; large extruded pipes; hull structures of ships, vessels and articles of naval equipment.

Note

The alloy system Al-Mg. Corrosion resistant, easily deformable, thermally neurocinema alloy. Alloy 1561 is more expensive and specific than the metal stamps AMg5.
On the basis of alloy 1561 was created 1561Н alloy with a yield stress, and strength of at least 250 MPa and 360 MPa, respectively.
