Ibyuma bitagira umuyonga hamwe nicyuma cya grit ni ubwoko bubiri bwitangazamakuru bwamenyekanye cyane.Ibicuruzwa bikora kimwe no kurasa ibyuma hamwe nicyuma, icyakora, bikozwe mubyuma.Harimo kwibumbira hamwe kwa nikel na chromium.Nibintu byiza byo gusuzuma mugihe umwanda wanduye wakazi udashobora kwihanganira.Ibyo bicuruzwa byombi ni ibicuruzwa kandi rimwe na rimwe byitwa Cast Stainless Steel Shot na Cast Stainless Steel Grit.

Ikirahure kitagira umuyonga ni serefegitura.Icyuma kitagira umuyonga grit ntigisanzwe kandi ni inguni.Kurasa ibyuma bizatanga ubuso bworoshye kuruta ibyuma bya grit.Ibyuma bya grit, ukurikije imiterere yabyo, bizahita, cyangwa byangirika hejuru.Nubwo isasu ridafite umuyonga ntirishobora kumenyekana kurasa nkibitangazamakuru byemewe kurikurasa.

Byombi ibyuma bitagira umuyonga hamwe nicyuma kitagira ibyuma biza muburyo bukomeye nubunini.Ubwinshi bwinshi muri buri hejuru cyane kandi bugomba kwitabwaho bijyanye no gukoresha ibikoresho.Ibikoresho bikwiye bigomba gutoranywa kugirango bitange kimwe muri ibyo bicuruzwa.
