Titanium (ASTM B367) is very light and very strong. Whilst it is an expensive material weight for weight with many other materials, its high strength can be utilised to good effect in designs by reducing wall thickness and subsequently weight and cost. The poor wear and galling properties of Titanium must be considered in any design. Casting and welding processes are required to be conducted by specialists.
Titanium is immune to environmental attacks which makes it the perfect material for aerospace, jet engines, power generation and industrial applications where it can outlast competing materials but up to 5 times. It is the most noble metal and when coupled with dissimilar metals does not accelerate corrosion by galvanisation.
While Titanium is an element (No22) and is commercially pure, as a cast product it is often alloyed with small quantities of Palladium, Aluminium & Vanadium.
