Bivanye n’ibintu n’ibiranga vyavyo, ubwoko busanzwe bw’ivyuma bizunguruka ni ibi bikurikira: 1. Ivyuma bisanzwe vy’umuyagankuba; 2. High- Uburebure buto buto - ivyuma; 3. Ivyuma canke ibara ry’umubiri {{6}=zinc - ivyuma vy’agaciro; 4. Ivyuma vy’icuma n’ibindi bikoresho bidasanzwe.
1. Ivyuma bisanzwe vy’ivyuma vy’umuyagankuba ni vyo bikunze gukoreshwa cane, bitanga ubusudi bwiza cane n’ubushobozi bwo gukora. Ikoreshwa cane mu bikorwa bitandukanye vy’uguhingura ibintu n’ubuhinga.
2. Ibanze - imbere y'igihe -alloy icuma ni ikindi kintu kidasanzwe c'icuma. Inkomezi zayo nziza cane n’ubukomezi bwaco, hamwe n’ugusambuka kwayo gusumba abandi, vyatumye rikoreshwa cane mu nganda nk’ubwubatsi bw’ikiraro n’inyubakwa nyinshi {{4} =} kuba inyubakwa.
3. Ivyuma n’ibara ry’umubiri ({1}} zinc -aluminum ikoreshwa cane cane mu bikorwa bisaba uburinzi bw’ugusenyuka, nk’amahinguriro y’imiterere y’ivyuma n’ububiko bw’ibikoresho, bikaba bibuza neza gusenyuka no kwagura ubuzima bwavyo.
4. Ivyuma vy’ivyuma bitagira amababa n’ibikoresho bidasanzwe bikoreshwa cane mu vy’imiti, ivy’ubuvuzi, ivy’ibifungurwa, ivy’agaciro kanini{- hejuru y’ugushaza inzu n’ibindi bikorwa kubera ubushobozi bukomeye bwo gusenyuka n’uburebure bwiza kandi bwiza.
