With the continuous research on titanium metal, it plays an indispensable role in all walks of life. Due to its special characteristics, titanium metal can be used not only in general industry, but also in the aviation industry.
The specific strength (strength to weight ratio) of titanium and its alloys is very high among metal structural materials. Its strength is equivalent to that of steel, but its weight is only 57% of steel. In addition, titanium andits alloys have strong heat resistance and can still maintain good strength and stability in an atmosphere of 500°C, and the short-term working temperature can even be higher. Aluminum loses its original mechanical properties at 150°C and stainless steel at 310°C.
When aircraft missiles and rockets fly at high speeds, their engines and surface temperatures are quite high, and aluminum alloys are no longer capable. Titanium alloys are very suitable. It is precisely because titaniumand its alloys have comprehensive excellent properties of high strength, light weight, and strong heat resistance that when used to replace other metals in aircraft manufacturing, it can not only extend the servicelife of the aircraft, but also reduce its weight, thus greatly reducing the weight of the aircraft. Improve its flight performance. Therefore, titanium is one of the more promising structural materials for the aviation and aerospace industries.
