Extraction of Metals

Alloys - containing Titanium.

Titanium is mixed with aluminium (5%), and vanadium (5%).
Chromium and molybdenum might also be present.

Titanium is expensive, and is only used where its special properties
of low density, hardness and resistance to corrosion
can not be reproduced by cheaper materials.

Titanium alloys are used in
special parts of aircraft and ship construction,
nuclear reactors, chemical plant and hip joint replacements.
Titanium is being increasingly used in smart alloys.

Titanium can be used in small amounts in steel.
