Kamar yadda muka sani, graphite yana da halaye masu kyau waɗanda sauran kayan ƙarfe ba za su iya maye gurbinsu ba. A matsayin kayan da aka fi so, kayan lantarki na graphite galibi suna da halaye masu ruɗani da yawa a cikin ainihin zaɓi na kayan. Akwai tushe da yawa don zaɓar kayan lantarki na graphite, amma akwai manyan sharuɗɗa huɗu:
Domin kayan da wannan matsakaicin matsakaicin barbashi size, da ƙarfi da taurin na kayan tare da low resistivity ne kuma dan kadan m fiye da wadanda tare da high resistivity. Wato saurin fitarwa da asara za su bambanta. Saboda haka, juriya na ciki na kayan lantarki na graphite yana da matukar mahimmanci don aikace-aikacen aiki. Zaɓin kayan lantarki yana da alaƙa kai tsaye da tasirin fitarwa. Zuwa babban matsayi, zaɓin kayan yana ƙayyade yanayin ƙarshe na saurin fitarwa, daidaiton mashin ɗin da ƙarancin ƙasa.
A cikin masana'antar zane-zane ta musamman, ma'aunin gwajin taurin gaba ɗaya shine hanyar gwajin taurin Shore, wanda ƙa'idar gwajinsa ta bambanta da ta ƙarfe. Ko da yake a cikin fahimtar tunaninmu na graphite, yawanci ana ɗaukarsa abu ne mai laushi. Amma ainihin bayanan gwaji da aikace-aikacen sun nuna cewa taurin graphite ya fi na kayan ƙarfe. Saboda tsarin da aka tsara na graphite, yana da kyakkyawan aikin yankewa a cikin tsarin yanke. Ƙarfin yankan shine kawai kusan 1/3 na kayan jan ƙarfe, kuma saman injin yana da sauƙin ɗauka.
Duk da haka, saboda girman taurinsa, kayan aikin kayan aiki zai zama dan kadan fiye da na kayan aikin yankan karfe a yankan. A lokaci guda kuma, kayan da ke da babban taurin yana da kyakkyawan iko na asarar fitarwa. Don haka, taurin Shore na kayan lantarki na graphite shima ɗaya ne daga cikin zaɓin ma'auni na kayan lantarki na graphite.
Sannan akwai ƙarfin sassauƙan kayan lantarki na graphite. Ƙarfin gyare-gyare na kayan lantarki na graphite shine nunin kai tsaye na ƙarfin kayan aiki, yana nuna ƙaddamar da tsarin ciki na kayan. Kayan da ke da ƙarfi yana da ingantacciyar juriya mai juriya. Don na'urar lantarki tare da madaidaicin madaidaici, kayan da ke da ƙarfi mafi kyau ya kamata a zaba kamar yadda zai yiwu.
A karshe, da talakawan barbashi diamita na graphite lantarki kayan, da talakawan barbashi diamita na graphite lantarki kayan kai tsaye rinjayar fitarwa matsayi na kayan. Karami matsakaicin girman barbashi, mafi yawan fitowar uniform, mafi kwanciyar hankali yanayin fitarwa kuma mafi kyawun ingancin farfajiya. Mafi girman girman barbashi, saurin fitar da gudu kuma ƙarami asarar roughing. Babban dalili shi ne cewa makamashin fitarwa ya bambanta da ƙarfin halin yanzu yayin aikin fitarwa. Koyaya, ƙarshen farfajiyar bayan fitarwa ya bambanta tare da canjin barbashi.
Na'urorin lantarki na graphite na iya zama zaɓi na farko na kayan a masana'antu. Daidai ne saboda graphite lantarki suna da fa'idodi mara kyau cewa madaidaicin ma'aunin zaɓe na lantarki na graphite da zaɓin nau'ikan nau'ikan lantarki masu hoto masu dacewa sune maɓalli.
