We report the precise measurement of the flux of primary cosmic rays Silicon nuclei and its rigidity dependence, measured in the rigidity range from 2 GV to 3 TV with 1.6 million silicon nuclei collected by AMS-02 during the first 7 years of operation on board of the International Space Station (from May 2011 to May 2018). A comparison with other primary cosmic-ray fluxes (such as helium, carbon and oxygen) is also presented.
