Kubera iterambere ry’ubuhinga bw’ibikoresho, inkoni z’umuringa ziriko ziratera imbere zija ku bushobozi bwinshi no ku gukorana n’ibintu vyinshi-. Nk’akarorero, umuringa ufise zinc nyinshi- (ufise zinc irenga 40%) uratuma ushobora guhangana n’ugusenyuka mu kwongerako ibintu nka nickel na aluminium, bikaguma bikomeye mu gihe bituma ushobora gukoreshwa mu bibanza bikomeye vy’inganda. Umuringa udafise amabuye y’agaciro-udahungabanya ibidukikije (nk’uwa HWCuZn-1), biciye ku buhinga bwa microalloying, ntusubirira gusa umuringa w’amabuye y’agaciro-urimwo amabuye y’agaciro ariko kandi uragumya ubushobozi bwiza cane bwo gukoreshwa n’imashini, ukaba uhuye n’ibisabwa vyo kurinda ibidukikije vy’inganda z’ubuhinga bwa none n’amashanyarazi. Ikindi, ivyuma bishingiye ku muringa- (nk’inkoni zikozwe mu muringa-graphite) biragabanya cane ubushobozi bwo guterana mu kwongerako igice co gutera amavuta, bikaba vyerekana ubushobozi bwo gukoreshwa mu bihe vy’ugusambuka cane nk’ibikoresho bifatanya n’ibikoresho bifata amavuta.
