Icyuma kidashonga ni izina ry’icyuma gifite aloyi nyinshi, ahanini gikoreshwa kubera ubushobozi bwacyo bwo kurwanya ingese. Ikintu nyamukuru kiranga ubwoko bw’icyuma kidashonga ni uko byose birimo nibura 10.5% bya chromium.
Ijanisha rya karuboni mu cyuma rigira ingaruka ku bukomere, imbaraga zo gushonga no kudakora neza kw'icyuma. Icyuma cyoroshye, kizwi kandi ku izina ry'icyuma cyoroshye, gifite imiterere isa n'iy'icyuma, ariko cyoroshye kandi cyoroshye kugikora.
Icyuma gishyushye gihuza imikorere n'ubwiza. Kigizwe n'icyuma gikozwe mu ibati, chrome, zinc cyangwa irangi, ari byo by'inyongera bishyirwa ku buso bw'icyuma karemano.
Aluminiyumu n'ibindi byinshi byayo birwanya cyane ingese zitandukanye. Iyi mitungo yatumye aluminiyumu ikundwa cyane mu nganda z'ubwubatsi, ubwubatsi bwo mu mazi no gutwara abantu.
Imiyoboro y'icyuma ni imiyoboro miremire irimo ububobere ikoreshwa mu mirimo itandukanye. Ikorwa hakoreshejwe uburyo bubiri butandukanye butuma imiyoboro ishongeshejwe cyangwa idasobekeranye ikoreshwa ahantu hatandukanye.
Uduti tw'icyuma dufite uburyo bwinshi bwo gukoresha no gukoresha mu nganda. Ubwoko bwinshi bw'ibigize alloy bushobora kuba burimo icyuma, bigatuma kiba ibikoresho bifite uburyo bwinshi bwo gukora uduti tw'icyuma cya karuboni n'uduti tw'icyuma kitagira umugese.
Insinga ni ubwoko bw'icyuma gishyushye gikozwe mu buryo bukurikije imiterere. Gishobora kuba icyuma cya karuboni cyangwa icyuma kitagira umugese. Insinga zikoreshwa nk'ibikoresho byo gufatanya, amasoko, imigozi y'insinga n'umuyoboro w'insinga.
Icyuma gifite imiterere myinshi itandukanye, bitewe n'ibindi bintu bigigize. Icyuma ni kimwe mu bikoresho bikoreshwa cyane mu nganda kandi ni icyuma gishobora kongera gukoreshwa cyane ku isi.
Ingano y'ibicuruzwa n'ibikenewe yarahagaze, kandi isoko ry'ibyuma mu Bushinwa ryazamutse gato kuva muri Nyakanga
