Light alloy mainly refers to titanium alloy, magnesium alloy and aluminum alloy. Among them, titanium alloys are made from titanium and other element.At natural temperature, titanium alloy can be divided into the following three types: α alloy, (α+β) alloy and β alloy.The machinability of α titanium alloy was the best, followed by that of (α+β) titanium alloy. The machinability of β ftitanium alloy was the poorest. http://www.chtitanium.com/products
With the development of science and technology and the increasing frequency of aerospace activities, light-weight trend has become the mainstream in the aerospace manufacturing industry, and the newly light-weight alloy material with the light-weight effect has been applied more and more widely in the aerospace field. According to the research report of 2018-2023 application market demand and development opportunities of China's light alloy industry released by researchers, the application volume of light alloy in China's space industry increased from 278,500 tons to 33.39 million tons in 2015-2017.
Titanium alloy is mainly used for manufacturing materials of aircraft and engine, such as forged titanium fan, compressor disc and blade, engine cover, exhaust device and structural frame of plane girder. Using titanium alloy instead of stainless steel to produce high pressure compressor disc and blade can reduce the structure weight. In recent years, scientists have made new progress in studying the properties of titanium alloys. The highest working temperature of original titanium alloy made from titanium, aluminum, vanadium is 550 ℃ ~ 600 ℃, but the newly developed titanium aluminum has been increased to 1040 ℃.
According to Bango Alloy researchers, the titanium alloy used for aviation accounts for half of the application of titanium alloy. From the perspective of global scope, the consumption of titanium alloy and titanium products is mainly concentrated in the aviation industry and the industrial field. The consumption proportion of global commercial aviation is about 42%, and the proportion of military titanium is about 7%. http://www.chtitanium.com/products
