ATOMIC STRUCTURE OF TITANIUM
Titanium has a melting point of 1660 +/- 10°C, boiling
point of 3287°C, specific gravity of 4.54, with
a valence of 2, 3, or 4. Pure titanium is a lustrous
white metal with low density, high strength, and high
corrosion resistance. It is resistant to dilute sulfuric
and hydrochloric acids, moist chlorine gas, most
organic acids, and chloride solutions. Titanium is only
ductile when it is free of oxygen. Titanium burns in air
and is the only element that burns in nitrogen.
Titanium is dimorphic, with the hexagonal a form
slowly changing to the cubic b form around 880°C.
The metal combines with oxygen at red heat
temperatures and with chlorine at 550°C. Titanium is
as strong as steel, but it is 45% lighter. The metal is
60% heavier than aluminum, but it is twice as strong.
Titanium metal is considered to be physiologically inert. Pure titanium dioxide is reasonably clear, with an
extremely high index of refraction and an optical dispersion higher than that of a diamond. Natural
titanium becomes highly radioactive upon bombardment with deuterons.
TITANIUM ALLOY MADE OF
Titanium is considered to be one of the strongest metals. Its strength, heat, water and salt resistance, and
its light weight make it the ideal metal for a variety of applications. These applications range from jewelry
and dental implants to airplanes and ships. Pure titanium is strong and corrosive resistant. Titanium alloys
retain the same strength and corrosion resistance, but takes on the greater flexibility and malleability of
the metal it is combined with. Titanium alloys, therefore, have more applications than pure titanium. There
are six grades of pure titanium (grades 1,2,3,4,7 and 11) and 4 varieties of titanium alloys. Titanium alloys
typically contain traces of aluminum, molybdenum, vanadium, niobium, tantalum, zirconium, manganese,
iron, chromium, cobalt, nickel, and copper.
