Icyuma gishyushya amashanyarazi (umuyoboro w'amashanyarazi) ni umuyoboro w'icyuma nk'igikonoshwa, kandi insinga zishyushya amashanyarazi (nikel-chromium, icyuma-chromium alloy) zikwirakwizwa kimwe ku murongo wo hagati w'igituba. Ibyuho byuzuzwa kandi bigashyirwa hamwe nifu ya magnesium oxyde hamwe nubushakashatsi bwiza hamwe nubushyuhe bwumuriro. Impera zombi zifunze hamwe na silika gel cyangwa ceramics. Iki cyuma gishyushya amashanyarazi gishobora gukoreshwa cyane mugushyushya amazi, amavuta, umwuka, igisubizo cya nitrate, igisubizo cya aside, igisubizo cya alkali hamwe nicyuma gike cyo hasi (aluminium, zinc, amabati, babbitt alloy), Ifite ibyiza byo gushyushya neza , ubushyuhe bumwe, kurwanya ubushyuhe bwinshi, kurwanya ruswa, no gukora neza umutekano.
