High Hardness and Good Quality Hip Silicon Nitride Precision Ball

Description:

Silicon Nitride Ceramic Balls Is a superhard material, which has lubricity and wear resistance. It does not react with other inorganic acids except for hydrofluoric acid, moreover,it has strong corrosion resistance and high temperature oxidation resistance.And it can also resist cold and heat shock, heat up to more than 1000 degrees in the air, rapid cooling and then rapid heating, and will not break.
