1 1. Owing to their strength, resistance to corrosion and their ability to withstand high temperatures without getting deformed, titanium alloys are used to make critical parts of aircraft, rockets and missiles among others. One important application of this metallic material is in the manufacture of jet engines.nywhere between 18 and 146 metric tons of titanium is used in the manufacture of most aircraft today. This is especially important in the construction of jet engines which features rotors, hydraulics, nacelles and compressor blades.
