Utwuma tw’inganda dukora mu buryo butandukanye n’ibipimo. Utwuma tw’icyuma dufite ubushobozi bwo guhagarika imbaraga nyinshi cyane bitewe n’ubushyuhe, bigatuma duhitamo iyi aluminium mu gihe dukora ibyuma bikoreshwa mu nganda. Utwuma twa Ferroalloy dufite karuboni nyinshi kandi dufite imiterere iri hejuru cyane kurusha icyuma cy’umwimerere, cyoroshye cyane. Birumvikana ko uretse karuboni, ibintu bihamye nka manganese, silikoni, sulfur, fosifore, ndetse rimwe na rimwe na vanadium (vanadium yongerwa ku byuma bisaba uburimbane) biboneka mu byuma.
Mu nganda z'ubwubatsi, imigozi n'imbuto bikoreshwa cyane mu gukora amazu y'inyubako, ibiraro, ingomero n'inganda z'amashanyarazi. Mu by'ukuri, ikoreshwa ry'imigozi n'imbuto bikoreshwa mu buryo butandukanye hakoreshejwe gusudira ibyuma, bivuze imigozi cyangwa gusudira imigozi hakoreshejwe electrode, bitewe n'uko bikenewe guhuza icyuma n'umugozi. Buri buryo bwo guhuza bufite ibyiza n'ibibi byabwo, tuzasuzuma hano hepfo.
Utwuma tw’ubwubatsi dukoreshwa mu guhuza imiyoboro y’ubwubatsi dukozwe mu cyuma cyo mu rwego rwo hejuru, ubusanzwe icyuma cya 10.9. Utwuma twa 10.9 bivuze ko ubucucike bw’imbaraga zo gukurura utwuma tw’ubwubatsi ari hafi 1040 N/mm2, kandi dushobora kwihanganira kugeza kuri 90% by’imbaraga zose zikoreshwa ku mubiri w’utwuma mu gace karahutse nta guhindagurika guhoraho. Ugereranyije n’icyuma cya 4.8, icyuma cya 5.6, icyuma cyumye cya 8.8, utwuma tw’ubwubatsi dufite imbaraga zo gukurura kandi dufite uburyo bwo kuvura ubushyuhe bugoye cyane mu gukora.
Bitandukanye n'udupira n'imbuto za hexagon bisanzwe, udupira n'imbuto za hexagon bisanzwe bikorwa hakurikijwe DIN931 bisanzwe nk'udupira duto, hakurikijwe DIN933 bisanzwe nk'udupira twuzuye, kandi utupira duto tworoshye, akenshi dukora hakurikijwe DIN6914. Guhuza imbuto ku mpande zombi bifite inyama nyinshi n'uburebure bwinshi kurusha utupira duto twa hexagon twakozwe nka DIN934, bigaragaza ko dufite ubushobozi bwo guhangana n'imihangayiko myinshi, twakozwe nka DIN6915. Utupira tw'iyi shusho dufite ikimenyetso cya 10HV kandi akenshi tuba dufite fosfati y'umukara ya matt kugira ngo turusheho kurwanya ingese mu bidukikije cyangwa tumeze nk'ifeza ishyushye cyangwa ifeza ya matt ya chrome, byombi bifite irangi ry'icyuma. Bikoreshwa muri zinc kandi bifite ubushobozi bwo kurwanya ibidukikije neza.
