Composition H-6

Composition H-6 is a melt-cast military aluminized high explosive. H-6 was developed in the US

The chemical composition of H-6 is specified as follows:

• 45.1 ± 0.3% RDX
• 29.2 ± 3.0% TNT
• 21.0 ± 3.0% powdered aluminium
• 4.7 ± 1.0% paraffin wax as a phlegmatizing agent.
• 0.47 ± 0.1% calcium chloride

Comp H-6 is used in a number of military applications, specifically as a explosive main fill, in munitions including aerial bombs such as the general purpose Mark 80 bombs in use with the USMC and US Navy (while USAF Mark 80s use a tritonal main fill); and underwater munitions (e.g. naval mines, depth charges and torpedoes) where it has generally replaced torpex, being less shock-sensitive and having more stable storage characteristics. It is approximately 1.35 times more powerful than pure TNT.
