Here is some light reading. Type in any kind of topic in this search and you will find something. I had some fun reading about the Soviets use of titanium back in the day.

Russian has most ore for titanium.
Titanium has the strength of steel and weight of aluminum and takes a higher heat than aluminum.
Great for frosting and paint too.

Great for jet aircraft skin for high temperature.

There are aluminum alloys that can same strength as steel but will not take heat.

Today you see a lot titanium in ads but mainly for advertising the product

Best story I ever heard about Titanium sales and seeing the CIA and Russian link above was how the CIA bought it from the Russians in fairly large quantities to build the A-12 Archangel, YF 12 Interceptor, and SR 71 Blackbirds.

My Pontiac SD engine had Inconel 751 exhaust valves installed from the Pontiac factory in "1973"

Pontiac was ahead of its time on those High heat exhaust valves.
Always thought it was neat that those exhaust valves shared basically the same material used in the skin of the X- 15
