... 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." |
