Umuringa wera(cupronickel), ubwoko bwiza bw'umuringa. Nifeza yera, niyo mpamvu izina umuringa wera.
Igabanijwemo ibyiciro bibiri: igikombe gisanzwe hamwe na cupronickel igoye. Igikombe gisanzwe ni amavuta y'umuringa-nikel, nayo yitwa "De Yin" cyangwa "Yang Bai Tong" mu Bushinwa; cupronickel igoye igabanijwemo cyane cyane icyuma cya cupronickel, manganese cupronickel, zinc cupronickel na aluminium cupronickel.
Cupronickel ifite imbaraga zo kurwanya ruswa, guhindagurika neza no gukomera cyane, kandi ikoreshwa kenshi mubwubatsi bwubwato, ingufu zamashanyarazi, inganda zimiti, kwivuza nizindi nzego. Kurugero, ibikoresho bya elegitoroniki byo murwego rwohejuru bikoresha ibikoresho bya cupronickel
Ingaruka ni uko kubera kongeramo ibintu bidasanzwe, igiciro gihenze kuruta umuringa n'umuringa.
Igipimo rusange cyo kurambura umuringa wera ku isoko ry’Ubushinwa ni 25%, ariko turashobora guhitamo umusaruro dukurikije ibipimo by’iburayi n’Amerika, bigera kuri 38%; ibintu bya trace nabyo birashobora kuvangwa ukurikije ibyo umukiriya asabwa.
