Gukata ibyuma byubusa bivuga ibyuma bivanze byongeramo umubare munini wibintu bimwe cyangwa byinshi byo gukata kubuntu nka sulfure, fosifore, gurş, calcium, selenium, tellurium, nibindi kugirango bitezimbere.Hamwe na automatike, yihuta kandi yuzuye yo gukata, ni ngombwa cyane gusaba ibyuma kugira imashini nziza, ikoreshwa cyane cyane mugutunganya imashini zikata byikora.Ibikurikira byibanda ku itandukaniro riri hagati yicyuma 1215 cyo gukata kubuntu na 11SMn30 ibyuma byubusa.
1215 ni ubwoko bwibyuma byoroshye gukata murwego rwabanyamerika ASTM / AISIBI.1215 gukata ibyuma byubusa ni ibikoresho byangiza ibidukikije bitarimo isasu cyangwa ibintu byangiza ibidukikije.Ifite ibintu byiza byo gukata kandi irakwiriye muri rusange amashanyarazi, ibikoresho byo gutema, nibice rusange.
