Xa ukhetha indawo yokumisa izixhobo ezinobuthathaka ezifana neenkqubo zesandi, izixhobo zesayensi, okanye oomatshini bemizi-mveliso, ukhetho lwezinto lunokuchaphazela kakhulu ukusebenza. Izinto ezisetyenziswa kakhulu ziquka i-granite, i-aluminium kunye nentsimbi. Izinto nganye ineempawu ezizodwa ezichaphazela amandla ayo okufunxa uloyiko, nto leyo ebalulekileyo ekugcineni ukuchaneka nokucaca kwizicelo ezahlukeneyo.
Iziseko zegranite zaziwa ngokukwazi kwazo ukufunxa ukutshayisa. Ubume begranite obuxineneyo nobuqinileyo buyivumela ukuba ifunxe kwaye isuse ukungcangcazela ngempumelelo. Olu phawu luluncedo ngakumbi kwiindawo apho ukungcangcazela kwangaphandle kunokuphazamisana nomlinganiselo obuthathaka okanye umgangatho wesandi. Iimpawu zendalo zegranite zinceda ukuzinzisa izixhobo, nto leyo eyenza ukuba ibe lukhetho olukhethwayo lwezixhobo zesandi eziphezulu kunye nezixhobo ezichanekileyo.
Xa kuthelekiswa, iziseko ze-aluminiyam nezentsimbi, nangona zomelele kwaye zihlala ixesha elide, azikwazi ukufunxa ukungcangcazela njenge-granite. I-aluminiyam ilula kwaye ingayilelwa ukusetyenziswa ngendlela ethile, kodwa idla ngokudlulisela ukungcangcazela endaweni yokuyifunxa. Intsimbi, kwelinye icala, inzima kwaye iqinile kune-aluminiyam, nto leyo enceda ekunciphiseni ukungcangcazela ukuya kuthi ga kwinqanaba elithile. Nangona kunjalo, isenazo iimpawu eziphezulu zokufunxa ukungcangcazela ze-granite.
Ukongeza, igranite ngokubanzi ineefrikhwensi eziphantsi zokurhawuzelela kune-aluminium kunye nentsimbi, oko kuthetha ukuba inokusingatha uluhlu olubanzi lweefrikhwensi ngcono ngaphandle kokuzikhulisa. Oku kwenza iziseko zegranite zisebenze ngakumbi kwiindawo apho ukungcangcazela okuphantsi kuyingxaki.
Ukuqukumbela, xa kufikwa ekufunxeni i-shock, i-granite yeyona ndlela ilungileyo xa ithelekiswa neziseko ze-aluminium okanye zentsimbi. Uxinano lwayo, ukuqina kwayo kunye nokuphindaphinda okuphantsi kwenza ukuba ilungele ukusetyenziswa okufuna ukuchaneka okuphezulu kunye nokuphazamiseka okuncinci kokungcangcazela. Kwabo bafuna ukusebenza kakuhle kwizixhobo zabo ezibuthathaka, ukutyala imali kwisiseko se-granite sisigqibo sobulumko.
