Application prospects of aluminum alloy forgings

In recent years, due to the decrease in the cost of aluminum materials, the improvement in performance, and the expansion of varieties and specifications, its application fields have become more and more extensive. Mainly used in aerospace, transportation, automobile, ship, energy power, electronic communication, petrochemical, metallurgy and mining, machinery and electrical appliances and other fields.

Due to the above series of advantages, aluminum and aluminum alloy forgings are favored in aerospace, automobile, shipbuilding, transportation, weapons, telecommunications and other industrial sectors, and their application range is becoming wider and wider. According to preliminary statistics, aluminum forgings accounted for 0.5% (18,000 tons) of the world's total output of forgings in 1985, and rose to about 18% in 2008. At present, the world consumes about 8 million tons of forgings, of which aluminum forgings account for about 1.85 million tons per year.

Due to the high cost and difficult production technology, aluminum alloy forging materials are only used in particularly important stress-bearing parts, and the proportion is not large. However, aluminum forging is the fastest-growing aluminum material. In the past ten years, due to the modernization and lightweight needs of military and civilian industries, especially the transportation industry, the demand for replacing steel with aluminum is very urgent. Therefore, aluminum The varieties and applications of forgings have grown rapidly.

In order to meet the increasing requirements of military and civilian sectors for aluminum and aluminum alloy forgings, countries around the world are concentrating manpower, material and financial resources on the development of aluminum forging production, designing and manufacturing various forging equipment, especially large and medium-sized forging presses. However, because the forging equipment is relatively expensive, the manufacturing cycle is long, and the forging production technology is relatively complicated, it is difficult to meet the needs of the market.
