Titanium copper looks a bit like Berryllium copper which we used to use alot for downhole applications. Magic properties: high yield, high electrical conductivity, magnetically transparent, high toughness and elongation, corrosion resistant, and fantastic lubricity and galling resistance.

Unfortunately Be is toxic so nobody wants to deal with the QHSE so its largely been replaced by copper nickle tin alloys. I have seen copper titanium alloys for magnetic sensing tools downhole but not that familiar with it, seems advertised for similar properties.

45k seems crazy even if made one at a time by EDM
