Titanium is used regularly in aviation for its resistance to corrosion and heat, and its high strength-to-weight ratio. Titanium alloys are generally stronger than aluminium alloys, while being lighter than steel. It has been used in the earliest Apollo Program and Project Mercury. [36]
Aluminum is also a ductile, light, and forms a very resistant oxide shell. The main advantage is that it has better strength to weight ratio than steel which makes it ideal for certain narrow applications. Now titanium-nitride is harder than steel, but it's a nonmetallic ceramic (crystal), and so has all the downsides of a ceramic.
They are expected to be thermally and chemically more stable than diamond, and harder than c-BN, and would therefore be excellent materials for high speed cutting and polishing of ferrous alloys. These characteristic properties are attributed to the diamond-like structure combined with the sp3 σ-bonds among carbon and the heteroatoms.
Titanium is used in steel as an alloying element (ferro-titanium) to reduce grain size and as a deoxidizer, and in stainless steel to reduce carbon content. [11] Titanium is often alloyed with aluminium (to refine grain size), vanadium , copper (to harden), iron , manganese , molybdenum , and other metals. [ 96 ]
Titanium aluminide (chemical formula TiAl), commonly gamma titanium, is an intermetallic chemical compound. It is lightweight and resistant to oxidation [1] and heat, but has low ductility. The density of γ-TiAl is about 4.0 g/cm 3. It finds use in several applications including aircraft, jet engines, sporting equipment and automobiles.

The principle is that an object made of a harder material will scratch an object made of a softer material. When testing coatings, scratch hardness refers to the force necessary to cut through the film to the substrate. The most common test is Mohs scale, which is used in mineralogy. One tool to make this measurement is the sclerometer.
Like many other alloys, titanium gold alloys have a higher yield strength, tensile strength, hardness, and magnetism than either of its constituent metals. [ 4 ] In July 2016, researchers led by Emilia Morosan at Rice University discovered that a titanium-gold alloy, β-Ti 3 Au, is an intermetallic alloy that is up to 4 times harder than pure ...
