Aluman

Aluman® – resistant even at very high temperatures
The alloy with the highest melting point of all aluminium alloys. Its good thermal conductivity makes the alloy perfectly suited to the manufacture of cast parts such as heat exchangers. Aluman parts display a high solidification temperature which means that they remain solid when surrounding aluminium alloys are liquid. A workpiece cast from Aluman can therefore be brazed with another free-flowing alloy.

Its counterpart in nature is fresh water icebergs which float in the salt water of polar seas as they don't share the same melting point.
