Technical characteristics

The structure of AMG3H alloy is an α-hard solution of magnesium in aluminum. The metal is alloyed with Mn, Fe, Zn, Cu, Ti to improve technological properties. The basis of the chemical composition consists of three components: Al - the main element, manganese and magnesium. (The chemical composition is regulated by GOST 4784-97). The composition of the alloy also includes other elements. Magnesium and copper give the alloy strength. Manganese, due to its properties, refines the structure, thereby increasing corrosion resistance and strength. In addition to these elements, the composition also uses silicon and iron.

Percentage composition (GOST 4784-97)

Fe Si Mn Cr Ti Al Cu Mg Zn Impurities
≤ 0.5 ≤ 0.4 0.2 - 0.6 ≤ 0.05 ≤ 0.15 95.7 - 98.2 ≤ 0.15 1.7 - 2.4 ≤ 0.15 ≤ 0.15

This alloy is considered to be one of the basic alloys for the production of pipes, sections, sheets, wires, forgings. Thanks to alloying, the products of this grade are characterized by excellent processability and excellent resistance to possible cracks. In accordance with GOST 1583-93 the amount of alloying components in the manufacture of bars and sheets is in the range of 5-6%. Thanks to the versatile mechanical and physical characteristics of sheet AMG3H, is widely used in the manufacture of various semi-finished products. The letter H means that the alloy is hardened, and the number 3 corresponds to the percentage of magnesium in the alloy.


A heat-treated version of rolled steel is produced. Excellent ductility is obtained after annealing, and considerable self-strengthening occurs after aging. Annealing. The alloy is heated to t° 500°C. When cooled, it acquires the flexibility similar to pure aluminum. After the aging process, hardness and toughness become the leading properties. To accomplish natural aging, approximately 24 hours and a working t° of 20 degrees Celsius are required. Artificial aging requires a higher temperature, but much less time. Upon completion of the treatment technology, AMG3H becomes a sufficiently strong and reliable material that can be used under high loads. It should be noted that natural aging after deformation reduces the strength limit compared to the strength of those parts that have aging after the necessary deformation. The sheet or plate of AMG3H is necessarily coated with a protective layer to improve corrosion resistance. Anodizing is another way to improve the characteristics of the semi-finished product.

Advantages of

- heat resistance;

- suitability for roller and spot welding;

- ductility, strength;

- good accessibility to stamping, cutting, polishing;

- low weight of products,

- low rate of cracking;

- resistance to vibration loading.


Mechanical engineering, aircraft construction, production of high-speed trains, construction of residential or industrial buildings. The preferred use of this alloy is due to its greater hardness than aluminum. Due to its corrosion resistance, aluminum tube of this grade has gained well-deserved popularity in many industries. It is used for welding of high-strength constructions, manufacturing of industrial pipelines and complicated profile parts.
