Titanium forgings that are used with Commercially Pure Alloys (Grade 1 ,Grade 2, Grade 3, Grade 4) are primarily used in Aircraft Frame applications.
Titanium alloys like 6AL-4v, 8Mn, 8Al-1MO-1V, 5Al-2.5Sn, and 6Al-2Sn-4Zr-2Mo, are also used in Aircraft engine applications due the ability of these alloys to with stand high temperature environments.
