At present, aluminum alloys are widely used alloys after iron-carbon alloys in the production of mechanical engineering parts. The article presents the process of alloying an alloy of grade 8176 aluminum with a combination of lithium fluoride. Bunda quoted the legirlash process in the same way. In the first method, lithium fluoride powder was mixed with a halide aluminum alloy wrapped in aluminum foil. In the second method, lithium fluoride powder was mixed with an aluminum alloy without exposure. Experiments have shown that a combination of 3 different amounts of lithium fluoride is introduced into the aluminum alloy. A combination of lithium fluoride is mixed in an amount from 5 gr to 15 gr. The experiments were carried out in a muffle furnace of the brand SNOL-1,6.2,5.1/11-I2M. The experiments carried out led to the fact that the furnace is set to 750 °C. In the article, the authors identified a lot of details of the samples obtained during the experiments and presented the relevant analyses and conclusions.
