why is titanium expensive
Titanium is very expensive because it is awkward to extract from its ores-for example, from rutile, TiO2. You can't use carbon reduction Titanium can't be extracted by reducing the ore using carbon as a cheap reducing agent.t has a relatively low density (about 60% that of iron). It is also the tenth most commonly occurri â¦ ng element in the Earth's crust. That all means that titanium should be a really important metal for all sorts of engineering applications. In fact, it is very expensive and only used for rather specialised purposes.
