Icuma c’umugozi, igikoresho gisanzwe c’ivyuma, gifise uruhara runini mu nganda, mu buhinzi, mu vy’ubwubatsi, no mu buzima bwa misi yose kubera imiterere yaco yihariye y’umubiri be n’uko gishobora gukoreshwa cane. Inyungu zayo zigaragara canecane mu bintu bikurikira.
Ica mbere, umugozi w’icuma urafise inkomezi nziza cane be n’ubukomezi. Mu bisanzwe ikozwe mu cuma gikomeye canke mu cuma kitagira ibara, irashobora kwihanganira inguvu nyinshi zo gukomera no gukomera ataco ivunitse, ivyo bikaba bituma ibereye gukoreshwa mu bikorwa bisaba inguvu zo hanze, nk’ugukomeza inyubakwa, gukingira uruzitiro no gutera imigozi. Vyongeye, ukuntu ishobora guhindurwa bituma yoroha kuyikora no kuyipfukamira mu mibumbe itandukanye kugira ngo ishobore gushitsa ivyo ikeneye mu buryo butandukanye.
Ubwa kabiri, umugozi w’icuma ntuzimvye cane kandi urakora. Ugereranije n’ibindi bikoresho vy’ivyuma, urutsinga rw’icuma rurafise uburyo bwo kurukora bukomeye be n’ibikoresho vyinshi bitagira agaciro, ivyo bikaba bituma rudazimvye cane. Ivyo bituma ari ikintu gikundwa cane mu bikorwa vyinshi nk’urusenga rwo gukingira mu buhinzi n’ibikoresho vyo gutera imigozi mu nganda, aho bituma bikora neza mu gihe bigenzura neza ibiciro.
Ikindi, umugozi w'icuma werekana ubushobozi bwiza cane bwo kunanira uburozi no gukomera. Kubera ko umugozi w’icuma ushizweko ivyuma bikomeye, ushizweko nickel-, canke ivyuma bitagira ibara, urashobora kunanira neza ubukonje, ugusenyuka kw’ivyuma be n’ugusenyuka kw’imiti, ivyo bikaba bituma umara igihe kirekire. Nk’akarorero, umugozi w’icuma ukoreshwa cane mu gukingira hanze no mu gukora uburimyi, mu gihe umugozi w’icuma udashobora gusenyuka ukoreshwa cane mu bidukikije bishobora gusenyuka cane nk’ivy’ubuhinga bw’imiti n’ivy’amazi.
Ubwa nyuma, umugozi w’icuma urashobora gukoreshwa mu buryo bwinshi cane, ukaba upfutse hafi inganda zose. Mu kwubaka, ikoreshwa mu gukomeza beton no mu gutera ivyuma; mu buhinzi, ikoreshwa mu gukingira uruzitiro no mu gushigikira; kandi mu buzima bwa misi yose, rikoreshwa mu kuboha, gufatanya no gushaza. Kubera ko ishobora gukoreshwa mu buryo bwinshi, bituma iba ikintu gihambaye co gushingirako.
Mu ncamake, urutsinga rw’icuma, rufise ivyiza vy’uko rukomeye cane, rudahenda cane, rudashobora gusenyuka, kandi rushobora gukoreshwa cane, rurafise uruhara rudashobora gusubirizwa mu kibano ca none kandi ruzobandanya kwerekana agaciro karwo mu bintu bitandukanye.
