Description
Alloy Amg4,5 is used: for the manufacture of semifinished products by hot or cold deformation; details for aircraft and instrumentation.
Note
The alloy system Al-Mg.
ISO 209−1 alloy brand Amg4,5 is the designation AlMg4,5 and 5083.
Also similar in chemical composition and properties is an alloy AlMg5Cr (5056) chemical composition: Si ≤ 0,30%, Fe ≤ 0,40%, Cu ≤ 0,10%, Mn = 0,50−0,20%, Mg = 4,50−5,60%, Cr = 0.05 to 0.20%, Zn ≤ 0.10%, the mass fraction of each other (not regulated) impurities ≤ 0.05% of the total mass fraction of other impurities ≤ 0.15 percent.

Technological properties
| Name |
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. |
| 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. |
