TITANIUM (Ti, atomic number 22) is a lustrous, grey metallic element used
principally to make lightweight, resistant alloys. It is one of the transitional
elements of the periodic table and has many desirable properties, most notably
its incredible strength and durability.
Titanium is immune to corrosive attacks by saltwater and marine atmosphere, and
exhibits exceptional resistance to a broad range of corrosive gases, acids and
alkalis. Immune to microbiologically influenced corrosion, Titanium is
physiologically inert and hypoallergenic.
Titanium is virtually non-magnetic, as well, making it ideal for applications
where electromagnetic interference must be minimized.
Titanium exhibits a high strength to weight ratio. Pure titanium is stronger
than steel yet nearly 50% lighter. When added to various alloys, its hardness,
toughness and tensile strength can be increased dramatically.
Titanium is always found in combination with other substances, and occurs as
an oxide in ilmenite, rutile and sphene, and is present in titanates and in many
iron ores. Titanium is present in the ash of coal, in plants, and in the human
body. Titanium is ductile only when it is free of oxygen and nitrogen (air),
melting at 1660°C (3020°F) and boiling at 3287°C (5949°F).
The complex process of converting titanium ore into metal has been commercially
viable for a little more than 50 years. Since the commercial introduction of
titanium, its use has expanded by an average of 8% per year and its popularity
continues to grow. |
