Description
Alloy AMg6 is used: for the manufacture of ingots and slabs, semi-finished products (sheets, tapes, strips, plates, profiles, panels, pipes, wire, welding wire Svamg6, stampings and forgings) by hot or cold deformation; ring blanks manufactured by free forging and rolling machinery; parts of the internal planes of welded tanks and fuel tanks of cross-sectional area of 200 cm2 and a diameter of circumcircle up to 350mm suitable for use in the aviation industry and special machine building industries; extruded 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; oversized extruded pipe; seamless cold-deformed pipes of large; bimetallic sheets with steel 12X18H10T, is designed to manufacture flat adapter General purpose.
Note
The alloy system Al-Mg.

The value |
| Weldability |
The alloy is well welded all types of welding - TIG, contact, spot, and seam welding. Weld joint efficiency is 0.9-0.95 % of the strength of the basic material. |
| Pressure treatment |
Well-deformed in hot and cold condition. |
| Features of heat treatment |
Not heat-treatable alloy. |
| Corrosion resistance |
Alloy with excellent General corrosion resistance, not cloned to stress corrosion cracking and intergranular corrosion (especially in the annealed condition). For additional protection parts against corrosion is anodizing or applied coatings. The corrosion resistance of the alloy (and the weld) high, is almost the same as that of pure aluminum. |
| Machining by cutting |
Machinability is good. |
