Amfani
1.High wear-resistanceThe nika bukukuwa lalacewa-juriya ya fi na kowa alumina bukukuwa, lokacin da yake aiki, da ball ba zai gurbata da nika kayan, don haka zai iya ci gaba da tsarki da kuma inganta da kwanciyar hankali na nika kayan musamman yumbu glaze.
2.High DensityThe high yawa, high hardness da high nika haruffa ajiye lokaci nika, kara girman da smashing dakin.Don haka yana iya inganta aikin niƙa.
