About
Titanium
Titanium is a chemical element
with low density and is a strong, lustrous, corrosion-resistant transition metal with a silver color.
Titanium is a performance metal, first utilized by
the aerospace industry for its high strength-to-weight ratio, corrosion
resistance and durability.
In the 1950s, the titanium metal industry was established primarily in
response to the emerging aerospace industry, which used it in the manufacture
of airframe structural components and skin, aircraft hydraulic systems, air
engine components, rockets, missiles, and spacecraft, where these properties
are invaluable.
Alloyed & Unalloyed Titanium
Titanium can be alloyed with iron, aluminum,
vanadium, molybdenum, among other elements, to produce strong lightweight
alloys for aerospace (jet engines, missiles, and spacecraft), military,
industrial process (chemicals and petro-chemicals). There are the unalloyed
or CP (Commercially Pure) grades of titanium.
In its unalloyed condition, titanium is as strong
as some steels, but 45% lighter.
The most widely used of this Cp titanium are classified as Grades 1 thru 4, 7,
11, and 12. The higher the grade numbers, the higher the strength. The first
four titanium grades allow for increasing levels of impurities. Palladium is
added to titanium Grades 7 and 11, at about 0.2%, to improve its corrosion
resistance.
