What is the weight difference between a square foot of titanium and a square foot of aluminum?
It depends on how thick they are. A square foot is a unit of
area, not volume. The density of the two materials is 5500 kg/m3
for Ti and 2800 kg/m3 for Al. Assuming you had the same volume
(same area and thickness) the mass ratio would be 55/28.
