Iye zvino pamusika, mapenzura akawanda anotungamira anogadzirwa nechiyero chegraphite, saka nei achigona kuyera graphite kuita mapenzura anotungamira? Nhasi Furuite graphite xiaobian ichakuudza kuti nei sikero graphite ichigona kuve penzura inotungamira:
Nei flake graphite inogona kushandiswa sepenzura lead
Chokutanga pane zvose, inhema; Chechipiri, ine hunyoro hunosiya mucherechedzo sezvainotsvedza zvishoma pabepa. Kana ukatarisa pasi pegirazi rinokudza, kunyora kwepenzura kunoumbwa nezvikero zvidiki zvegraphite.
Maatomu e<em>carbon ari mu<em>flake graphite akarongwa muzvikamu, uye kubatanidza pakati pezvikamu hakuna simba zvikuru, nepo maatomu matatu e<em>carbon ari muzvikamu akasimba zvikuru, naizvozvo kana akatsikirirwa, mativi acho anotsvedza nyore, semurwi wemakadhi ekutamba. Nokusaidzira zvinyoronyoro, makadhi anotsvedza nepakati.
Kutaura idi, mutobvu wepenzura wakagadzirwa nechiyero chegraphite nevhu rakasanganiswa mune imwe chiyero. Maererano nemitemo yenyika, kune marudzi gumi nemasere emapenzura maererano nehuwandu hweflake graphite. "H" inomirira ivhu uye inoshandiswa kuratidza kuoma kwepenzura lead. Iyo yakakura nhamba pamberi pe "H", iyo yakaomesesa kutungamira, zvichireva kuti iyo yakakura chikamu chevhu rakasanganiswa negraphite mukutungamirira, zvishoma zvinooneka mazwi, ayo anowanzoshandiswa pakukopa.
