Babban tauri da ƙarancin nakasar zafi
Yawan granite yana da yawa (kimanin 2.6-2.8 g/cm³), kuma tsarin Young zai iya kaiwa 50-100 GPa, wanda ya zarce na kayan ƙarfe na yau da kullun. Wannan babban tauri zai iya hana girgizar waje da nakasa nauyi yadda ya kamata, da kuma tabbatar da lanƙwasa jagorar iyo ta iska. A lokaci guda, ma'aunin faɗaɗa layi na granite yana da ƙasa sosai (kimanin 5×10⁻⁶/℃), 1/3 kawai na ƙarfe na aluminum, kusan babu nakasar zafi a yanayin canjin zafin jiki, musamman ya dace da dakunan gwaje-gwaje na zafin jiki na yau da kullun ko wuraren masana'antu tare da babban bambancin zafin jiki tsakanin rana da dare.

Granite zuwa acid da alkali, mai, danshi da sauran abubuwan muhalli suna da juriya mai ƙarfi, babu buƙatar shafa layin hana tsatsa akai-akai kamar tushen ƙarfe. Bayan niƙa da gogewa, ƙaiƙayin saman zai iya kaiwa Ra 0.2μm ko ƙasa da haka, wanda za'a iya amfani da shi kai tsaye azaman saman ɗaukar kaya na layin jagorar iska don rage kurakuran haɗuwa.
Na biyu, iyakokin tushen dutse
Matsalar sarrafawa da matsalar farashi
Granite yana da taurin Mohs na 6-7, wanda ke buƙatar amfani da kayan aikin lu'u-lu'u don niƙa daidai, ingancin sarrafawa shine 1/5 kawai na kayan ƙarfe. Tsarin hadaddun ramin dovetail, ramukan zare da sauran fasalulluka na farashin sarrafawa yana da yawa, kuma zagayowar sarrafawa tana da tsawo (misali, sarrafa dandamalin 2m×1m yana ɗaukar fiye da awanni 200), wanda ke haifar da jimlar kuɗin ya fi dandamalin ƙarfe na aluminum girma da kashi 30%-50%.
Haɗarin karyewar karaya
Duk da cewa ƙarfin matsi zai iya kaiwa 200-300MPa, ƙarfin matsi na dutse shine 1/10 kawai. Karyewar da ta karye yana da sauƙin faruwa a ƙarƙashin nauyin tasiri mai tsanani, kuma lalacewar tana da wahalar gyarawa. Ya zama dole a guji yawan damuwa ta hanyar ƙirar tsari, kamar amfani da canjin kusurwa mai zagaye, ƙara yawan wuraren tallafi, da sauransu.
Nauyi yana kawo iyakokin tsarin
Yawan dutse ya ninka na aluminum sau 2.5, wanda hakan ke haifar da ƙaruwa mai yawa a cikin nauyin dandamalin gaba ɗaya. Wannan yana sanya buƙatar da ta fi girma akan ƙarfin ɗaukar nauyin tsarin tallafi, kuma matsalolin inertia na iya shafar aikin kuzari a cikin yanayi da ke buƙatar motsi mai sauri (kamar teburin wafer na lithography).
Anisotropy na kayan aiki
Rarraba ƙwayoyin ma'adinai na dutse na halitta yana da alaƙa da alkibla, kuma taurin kai da ƙimar faɗaɗa zafi na wurare daban-daban sun ɗan bambanta (kimanin ± 5%). Wannan na iya haifar da kurakurai marasa amfani ga dandamali masu matuƙar daidaito (kamar sanya nanoscale), waɗanda ke buƙatar ingantawa ta hanyar zaɓar kayan aiki da maganin daidaitawa (kamar calcination mai zafi).
A matsayin babban ɓangaren kayan aikin masana'antu masu inganci, ana amfani da dandamalin iyo mai daidaiton matsin lamba mai tsauri a cikin masana'antar semiconductor, sarrafa gani, auna daidaito da sauran fannoni.
