It's a ceramic. It is likely used in a composite structure, but is still probably pretty brittle. It is absolutely not a metal. Though considering the properties of actual aluminum, this is the only 'transparent aluminum' you're gonna get (well at least some ceramic). Metals , by their very nature can't be conductive (electrical conductivity makes being transparent kind of impossible). For thermal properties, I would  venture a guess that it was fairly conductive of heat since it can't be porous and transparent. If you have a material with strong bonds, you generally can get good conductivity (most commonly seen ceramics, however, are very porous which is why they conduct heat poorly). buzzard</blockquote>
