In this paper, we employed first-principle calculations to investigate the elastic properties, electronic properties and hardness of diamond and hexagonal W2B5 compounds under high pressure. The elastic properties were carried out to discuss the structural stability and the bond components of diamond and hexagonal W2B5. The electronic properties were presented to analysis the change of the bond components for W2B5. In addition, the hardness of these two crystals under high pressure was calculated by a semi-empirical method considering the role of metallic components and the effect of pressure on the hardness of diamond and hexagonal W2B5 was discussed.
