Circle, sheet, tube of AK7 aluminum

Technical characteristics

AK7 aluminum casting alloy is used in production of shaped castings. According to the old designation - AL9. The scope of use of silumin is quite extensive, as parts made of this material cope well with an average level of load. Through the use of silumin significantly increases the life of any product that is not subject to significant loads or vibration.

Percentage composition (GOST 4784-97)

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, the composition also uses silicon and iron up to 0.7%,. Fe is considered a harmful impurity, reduces strength and ductility. Si helps to reduce the harmful effects of iron, to a certain extent binding it. Due to alloying, silumin is characterized by excellent ductility in processing and excellent resistance to cracking. In accordance with GOST 1583-93 the optimum amount of silicon in the manufacture of silumin is 6-8% and the amount of foreign additives to 3.3%. Such a ratio of components in the alloy provides the products:

good casting properties;

excellent weldability;

ease of machining;

anticorrosive qualities.

low price,

biological inertness.

Relevance

Although silumin has average strength, but shows high corrosion resistance. Let us note the advantages of silumin over other materials. For example, AK7 pipe is cheaper than cast iron and is not inferior in wear resistance and lighter in weight. Another advantage of the material is that it is approved for the production of cookware. Sheet silumin is successfully used for the manufacture of forks, spoons, individual assemblies of meat grinders and other household products.
