Due to the low strength of pure aluminum, modern designers prefer to use its alloys. AK5 alloy is one of the most common aluminum alloys. The percentage composition of AK5 alloy: Mn - 0.2-0.6%, Zn - 0.3%, Cu - 1.9-2.7, Mg -0.8-1%, Ti - 0.1%, Fe - 0.8%. The remainder is aluminum. "K" in this abbreviation characterizes the silicon compound, and "5" in this case is its content in tenths of a percent.

Percent composition (GOST 4784-97)

Fe Si Mn Ni Cr Ti Al Cu Mg Zn Impurities
≤0,8 0,4-0,7 0,2-0,6 ≤0.1 ≤0.1 ≤0.1 93.1-95.5 1.9 -2.7 0,8-1,0 ≤0.3 ≤0.1

Magnesium and copper are used to impart strength to the alloy. Manganese, due to its properties, refines the structure, thereby increasing resistance to corrosion and strength. In addition to the above elements, silicon and iron are also used in the composition. Fe is considered a harmful impurity, reduces strength and ductility. Si helps to reduce the harmful effects of iron, binding it to a certain extent. The melting point of the alloy is 650 degrees.


The circle is a cylinder of standard length up to 6 meters with a diameter of 10-400 mm. Aluminum sheet of this grade or plate to improve corrosion resistance is necessarily covered with a protective layer. Anodizing is another way to improve the characteristics of the semi-finished product.

Heat Treatment

Heat-treated and unhardened versions of rolled products are produced. After annealing, excellent formability is achieved, and after aging, significant self-strengthening is achieved. Annealing. The alloy is heated to 500°C. When cooled, it acquires the flexibility of pure aluminium.


After the aging process, hardness and toughness become the leading properties. Natural aging requires about 24 hours and an operating temperature of 20 degrees Celsius. Artificial aging requires higher temperatures, but much less time. After the technology is complete, AK5 becomes a sufficiently strong and durable material that can be used under the highest loads. It is worth noting that natural aging after deformation reduces the ultimate strength by 2 kg/мм compared to the strength of those parts that have aging after the necessary deformation.


- heat resistance;

- suitability for roller and spot welding;

- low weight of products,

- low rate of cracking;

- resistance to vibration loading.

Disadvantages .

Firstly, it is high sensitivity to corrosion, especially under stress, which can be eliminated by cladding. Secondly, high sensitivity to sharp cuts. Thirdly, a significant reduction in strength characteristics at higher t° above 140 °C.


Mechanical engineering, aircraft construction, high-speed trains, residential or industrial construction. The preferred use of this alloy is due to its greater hardness compared to aluminum.
