Expensive commercial kitchen gear is generally aluminum or steel, and each has problems. Non-reactive titanium would work well for some things.

"Non-reactive titanium would work well for some things."

Titanium is FAR from being "non-reactive". What gives titanium metal parts relative inertness is the almost instantaneous formation of a very strong and tenacious oxide layer at the surface (like aluminum and magnesium, only more so).
