Key Points Of Aluminum Alloy Technology

Key points of aluminum alloy technology
The melting point of scandium is 1541 ° C, and the melting point of aluminum is 660 ° C. The difference in melting points between the two metals is too great. Scandium must be added to the aluminum alloy in the form of a parent alloy. Scandium base alloy is a key raw material for preparing aluminum alloys containing scandium. The preparation of parent alloys mainly includes several methods such as doping, scandium fluoride, metal thermal reduction, molten salt electrolysis, etc. The doping method is to directly add scandium metal to aluminum alloy for preparation. Scandium metal is expensive, the smelting process is large, and the cost of intermediate alloys is high; The metal thermal reduction method of scandium fluoride is highly toxic in the preparation of scandium fluoride. Hydrogen fluoride, with complex equipment and high metal thermal reduction temperature; The actual scandium production rate after thermal reduction of scandium oxide is only 80%; The molten salt electrolysis method has complex equipment and low conversion rate. After comparison and selection, it is more suitable to use the scandium chloride molten salt aluminum magnesium thermal reduction method to prepare aluminum scandium master alloy.
