[Properties]

  Titanium heads the list of Group-IVB elements, the so-called titanium
group of metals. Other members of this group are zirconium (Zr), hafnium
(Hf), and rutherfordium (Rf).
  Titanium is heavier than aluminum, but not quite as heavy as iron. It
can be highly polished, and is relatively immune to tarnishing under
normal environmental conditions. For a metal, it is not a very good
conductor; it is also paramagnetic - it shows little response to magnetic 
fields.
  Titanium has two temperature-dependent crystal forms, or allotropes.
The alpha form has a hexagonal structure and exists up to about 800
degrees. Above 800 degrees, titanium takes on its cubic beta form.
