“Of the first 6000 pieces fabricated from the beta titanium alloy, 95% were lost.”
Titanium is nearly as strong as stainless steel at 40% less weight, and it still lost the mass market. William Kroll could not sell his process when he brought it to the US in 1938. More than two dozen companies announced titanium plans between 1950 and 1952. A 2006 estimate put refining at five times the cost of aluminum and finished products at ten times, and that is why your car is not made of it.
