Umuringa-nikel
Kumenyekanisha ibicuruzwa
Umuringa-nikel uvanze bikozwe mu muringa, icyuma, nikel, zinc hamwe na sisitemu, binyuze mu gutunganya ingoti, kuzunguruka bishyushye, gukonjesha gukonje, kuvura ubushyuhe, gusukura hejuru, gukata, kurangiza, gupakira nibindi bikorwa.ibicuruzwa bifite urumuri rwiza, rwiza rushyushye nubukonje bukora, guhindagurika, kurwanya ruswa, kurwanya umunaniro, guhinduka kwinshi, ibintu byiza byamashanyarazi nubukanishi nibikorwa byo gukingira.Ikoreshwa cyane mugukora ibitangazamakuru bitose kandi byangirika mugikorwa cyibigize imiterere, ibice byoroshye, ibikoresho bisobanutse, inganda zitumanaho, ibikoresho byo mu bwoko bwa kristal oscillation inzu, ibikoresho byubuvuzi, ubwubatsi, ibikoresho byumuyaga nibikoresho bya buri munsi nibindi. .
