[Feature] The porous material prepared by spherical tungsten powder has the characteristics of uniform pore distribution. By controlling the production process, the gas permeability of the product can be controlled, and the cathode of high-power pulse microwave tube, electronic barium tungsten cathode and gas filter material can also be prepared; The tungsten powder has good fluidity, and the coating obtained in the field of thermal spraying is more uniform and dense, and the product has good wear resistance.
[Application field] It is used as the raw material of diamond drill bit (as matrix material) for petroleum drilling and petroleum perforating bullet, high temperature coating of combustion chamber and coating of other wear-resistant and high-temperature resistant parts.
[Specification] 0-20μm, 15-45μm, 15-53μm, 53-105μm, 53-150μm, 105-250μm Can be supplied according to customer requirements.
