Abstract The micro-mechanical properties (elastic modulus and hardness) of four energetic crystals of RDX, HMX, CL-20 and TKX-50 were studied by nanoindentation technique. The friction coefficient of explosive crystals was tested by explosive particle slip force measuring instrument. The friction sensitivity of energetic crystals was obtained by GJB772A-97 method 602.1, and the relationship between the micromechanical property and the frictional property of four kinds of energetic crystal was investigated. The results show that the elastic modulus and hardness of the four energetic crystals are low, and the order of size is TKX-50>CL-20>RDX>HMX. TKX-50 has better resistance to deformation. The friction coefficients of four kinds of explosive crystal are sorted in order: TKX-50
