This article estimates the production of master alloys Al – Ti, Al – Zr, Al – B, obtained by different methods: direct alloying aluminum with alloying component in pure form; aluminothermic reduction of fluoride complex salts; aluminothermic reduction of titanium oxide, zirconium and boron oxide in chloride-fluoride melts. The main item of expenditure in the production of master alloys by each of the methods is raw material costs, calculated on the first stage of the work. The most optimal parameters for master alloys Al – Ti, Al – Zr, Al – B are obtained during aluminothermic reduction of titanium oxide, zirconium, boron oxide, respectively. The production cost is calculated on the second stage of the research which includes additional items of expenditure, such as energy costs, raw material costs and the costs of the craft. The profitability and annual profit were calculated using the obtained numbers. Annual profit is 374 million rubles for master alloys Al – 5Ti using the oven IAT-6 (ИАТ-6), the profitability in this case is 15,11%. Annual profit is 600 million rubles for master alloys Al – 5Zr, the profitability in this case is 22,22%. Annual profit is 188 million rubles for master alloys Al – 5B, the profitability in this case is 12,43%.
