Gusukura icyuma gitunganya ubuhinzi mu cyuma cya Boron gifite uburebure bwa Mn 65, 60Si2Mn, 30MnB5 gifite ubushyuhe n'irangi.

Igikoresho cyo gukata ni cyo gice cy’ingenzi cy’isukari y’ibumba, gifite imiterere y’ubuso bumeze nk’umugozi. Gihuzwa n’umubiri w’isukari binyuze mu bice nk’urukuta rw’isukari n’ishingiro ry’isukari kugira ngo kigere ku nshingano zo gusya no guhindura ubutaka.
Ibikoresho by'ingenzi: Icyuma cya 65Mn cyangwa icyuma cya 60Si2Mn, gifite ubukana buri hagati ya HRC3 na 49. Hari ubwoko bwakoreweho isuku no gushyushya cyangwa gusiga irangi kugira ngo byongere ubushobozi bwo kudashira.
Binyuze mu ikoranabuhanga ryo gucura no gutunganya ubushyuhe, imiterere y'ibice irakorwa neza kandi ihamye.
