The metal titanium is the ninth most abundant element in the Earth's crust. like other metals, titaniumis shinyand strong. But, unlike mostother metals,it has quite a low density. Titanium does not corrode easily and has a very high melting point. All these propoties mean that titanium is a very useful metal. it can also be mixed with other metals to make titanium alloys- an alloy is a mixture of different metals.
