- [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.
