AFX-645

AFX-645 is an insensitive high explosive being explored by the U.S. Air Force in insensitive munition applications.

From the fabrication standpoint, is a melt castable formulation which could be easily processed in existing high-rate loading facilities.

It is composed of a well specified grade of nitrotriazolone (NTO), and other components for which detailed material specifications already exist. The AFX-645 wax/surfactant system is suitable for use in military environments. When compared with the conventional D2 wax system, the I-800/Ganex mix in AFX-645 minimizes exudation and off-gassing and enhances the TNT/wax emulsion characteristics. It also dramatically effects the shock sensitivity, critical diameter and energy of the mixture of aluminum powder, TNT and NTO. aluminized TNT/NTO formulation.

AFX-645 was developed by balancing energy and sensitivity requirements for surviving sympathetic detonation in the new standard metal pallet. AFX-645 blast performance measured in Mk- 82s approaches that derived from tritonal filled Mk-82s.
