How do aeroplane black boxes withstand crashes which otherwise destroy the plane and everything inside of it?

I get that they are built to a higher specification, but not how that is achieved.

Flight recorders are usually built with a compound casing of aluminium, steel and insulating material that can protect the electronics from high Impact and extrem temperatures. Compared to that aircrafts are built with the lightest possible materials, like alumium-carbon alloys. They can withstand the pressure of flight, but certainly not the extrem forces on impact. An airplane made out of blackbox material wouldnt be able to fly very far.
