Reflection capacity (Topic: 15046)
When a clean aluminium surface is exposed to a heat radiation source, most of
the heat energy will be reflected. The amount of reflection is dependent of the
condition of the surface.
For old oxidised aluminium surfaces the reflection of heat radiation will be
80ñ85%. For polished aluminium surfaces the reflection can be up to 97%.
