Tritonal is a mixture of eighty percent TNT and twenty percent aluminium powder, used in several types of ordnance such as air-dropped bombs. The aluminium improves the total heat output and hence impulse of the TNT - the length of time throughout which the blast wave is positive. Tritonal is approximately eighteen percent more powerful than TNT alone.

The 87 kg of tritonal in a Mark 82 bomb has the potential to produce approximately 863 MJ of energy if detonated.
