Molybdenum plates can be used as the lining for filling explosive warheads (known in military terms as charge caps), which can penetrate and cut to great depths in military and industrial applications. In such devices, the explosives surrounding the lining are detonated in a controlled manner, deforming the lining in a very peculiar way. The deformation creates rod-like fragments (ejectors) of the lining material with high velocity and high tension that can penetrate deeply into the target or target.

The development of molybdenum-lined explosive cap is a new research field. Replacing copper with molybdenum will be an important reform in ordnance. Conventional warhead drug type lining material is copper, but the velocity of molybdenum is 5.12 km/s (copper is 3.94 km/s), the density of 10.2 g/cm3 (copper is 8.93 g/cm3).

In order to obtain high speed coherent injection, the prongs must have high sound velocity. The injection speed with molybdenum is more than 12 km/s, while the speed with copper is less than 10 km/s. The speed difference between the two is 20%-25%. The reason is that the high speed of sound increases the energy of the tip, which leads to the improvement of the penetration.
