Titanium is a metallic element resembling iron.
It has been manufactured commercially since 1948 and it is a very useful metal because it is very strong, light and doesn't rust easily. This makes it ideal for use in the aircraft industry, in industries where you need a metal component that won't rust in a wet environment and in stainless steel. One of its oxidised forms, Ti02, is used in industrial paints and plastics as it makes a good white colour.
