1. Igipande c'icuma
Igipande c’icuma ni co gice nyamukuru c’umuyoboro w’icuma kidashobora gusenyuka, kikaba gifise ibice birenga 50% vy’inyubako yose. Itanga mbere na mbere inkomezi n’ukudashobora gusenyuka.
2. Urupande rwa koromu
Ico gipande c’ivyuma citwa chromium gikikuje ico gipande c’icuma, ahanini kigatuma iyo tiyo y’icuma idashobora gusenyuka kandi idashobora gusenyuka, kikabuza umugese wo ku ruhande rwo hejuru, guhindura ibara n’ugushaza. Amatiyo y’icuma kitagira ibara akenshi agira chromium nibura 13% kugira ngo yerekane ubushobozi bwiza bwo guhangana n’ugusenyuka.
3. Igipande ca nikele
Ico gipande c’ivyuma citwa nickel, kiri hagati y’ivyuma n’ivy’ivyuma vyitwa chromium, kiratuma iyo tiyo ikomera kandi ikaba ishobora gukomera, mu gihe nyene kirinda ico gipande c’icuma ngo ntikigire umwuka w’ivyuma. Amatiyo y'icuma atagira ibara afise nibura 8% vyitwa "nickel alloys."
4. Igipande ca karboni
Ico gice c’umuyagankuba gikora nk’ikintu gikuraho ubushuhe mu muyoboro w’icuma kitagira ibara. Ico gikora ni ugugabanya ubushobozi bw’uwo muyoboro bwo kwaguka mu gihe wongerera ubukomezi bwawo n’ubushobozi bwawo bwo guhangana n’ugusambuka, ivyo bikaba bituma urushiriza gukomera.
