• Discovery: at the end of
the 18th century
• Properties: Titanium is light and
strong at the same time, ductile,
corrosion and temperature resistant
• Occurrences: Pure titanium is rare.
the main source materials for the
manufacture of titanium are ilmenite
and rutile.
• Value: The extensive manufacturing
process is reflected in the high price:
titanium is approx. ten times more
expensive than conventional steel.
• Requirements for the forging process:
At higher temperatures titanium
becomes brittle quickly due to
Forging area in the press Forming process with special tools
Titanium – an element with many properties
the absorption of oxygen, nitrogen,
and hydrogen. this high reactivity of
the metal at increased temperatures
or at increased pressure requires a
highly precise adjustment of these
physical properties during the forging
process.
• Fields of application: Due to its high
corrosion resistance, titanium is, for
example, used as biomaterial for
implants in the medical industry as
well as in the fields of dentistry and
surgical orthopedy. In aircrafts and
space ships titanium is used in parts
that are highly stressed but yet have
to be light, for example, engine
parts.
