Ibikoresho byicyuma birimo umuringa mwinshi byitwa umuringa wera. Birazwi kandi nkaumutuku umuringa kubera ubuso bwacyo igaragaraibara ry'umutuku. Umuringa ufite urwego rwo hejuru rwo guhinduka no guhindagurika.
Umuringa ni uruvange rw'umuringa na zinc, bakunze kwita umuringa kubera ibara ry'umuhondo wa zahabu. Zinc mu muringa ituma ibikoresho bikomera kandi bikarwanya gukuramo, mugihe ibikoresho nabyo bifite imbaraga nziza.
Umuringa ni ibikoresho bivangwa no gushonga umuringa hamwe nibindi byuma bidasanzwe cyangwa by'agaciro. Ihuriro ritandukanye rya alloys rifite imiterere itandukanye kandiPorogaramu.
Beryllium Umuringa Foil ni ubwoko bumwe bwumuti urenze urugero wumuringa wumuringa wahujije ibintu byiza cyane byubukanishi, umubiri, imiti hamwe no kurwanya ruswa.
Ibikoresho byumuringa-nikel bikunze kwitwa umuringa wera kubera ubuso bwera bwa silver.nikel alloyni icyuma kivanze kandi kirwanya cyane kandi gikoreshwa nkibikoresho byangiritse. Ifite ubushyuhe buke bwo guhangana nubushyuhe bwo hagati hamwe no guhangana hagati (0.48μΩ · m).
