Titanium vs. aluminium

GLit- Let's see. the last B-52 was made about 40 years ago. They were all
made of
aluminum. They are still the backbone of SAC. The duty cycle and stress on a
B-52 is FAR higher than any bicycle has to endure. Any yet they fly.
BRBR

There is a lot of steel and probably titanium in all military aircraft.



"A variety of materials is used in the F-22 design. The distribution of
materials used by weight is as follows: 36% Ti-64 titanium alloy, 36%
thermoset composites (epoxy resin and bismaleimide, or BMI, in near-equal
proportion), 16% aluminum alloy, 15% other materials (including paint,
coatings, radome, transparency, tires, brakes, seals, sealants, adhesives,
actuators, fluids, and gases), 6% AirMet 100 steel alloy (offers greater
corrosion protection), 3% Ti-62222 titanium alloy (high-strength alloy), 1%
thermoplastic composites."
