Ko nga matatahi Cermet ehara i te mea he nui te pakeke me te uaua teitei hei rauemi turanga, engari ka tino whakatinanahia nga paerewa kounga e tika ana i roto i nga tukanga whakaputa o muri mai o te hurihanga mata-rua, te huri mokamoka me te hurihanga taha, kia pai ai te whakaputa tohu me te teitei- hua kounga. hua.
Kei te mohio katoa tatou ka taea te mohio te taumata tika o te mata mai i te tauira o te mata ISO, na i tenei ra ka whakauru tuatahi i nga korero e pa ana ki te tika o te taha o te mata huri ISO.
Hei tauira, ko te tauira o te mata o runga ko TPGH110304L10PK C3
Ko te tuatoru o nga reta G e tohu ana mo te tika, he whakaurunga hoha o te taumata huri.
