Igiciro cya karubide ya tungsten kigira ingaruka ku giciro cy'uduce two gucukura.

Bitewe n’izamuka ry’igiciro cya tungsten carbide, ibikoresho by’ingenzi bya roller cone na PDC bits, ibiciro by’umusaruro byazamutse cyane. Ibiciro by’ibikoresho fatizo bikomeje kuzamuka, ibintu bikarushaho kuba bibi. Ibikoresho byacu biri hafi kurangira. Kugira ngo dukemure ibi bibazo, tuzahindura ibiciro by’ibicuruzwa byacu. Twishimiye uburyo mutwumva mu gihe duharanira kubungabunga ubuziranenge.

Izamuka riherutse ry’ibiciro bya karuboni ya tungsten riterwa n’ibintu byinshi bifitanye isano. Inzitizi z’ibicuruzwa byiganjemo, mu gihe Ubushinwa—bukora 82.7% bya tungsten ku isi—bwashyizeho uburyo bukomeye bwo kugenzura ibicuruzwa bya tungsten nk’ibikomoka kuri ammonium paratungstate (APT) na tungsten oxide muri Gashyantare 2025, bigabanya ibyoherezwa mu mahanga ku kigero kirenga 80%. Hagati aho, itsinda rya mbere ry’ibicuruzwa bya tungsten mu 2025 ryagabanutseho 6.45% ugereranyije n’umwaka, Intara ya Jiangxi igabanya umusaruro ku kigero cya 10%. Iri gabanuka rya politiki ebyiri ryasize amasoko mpuzamahanga agoramye, cyane cyane mu gihe ibihugu by’Iburengerazuba bihanganye no gusimbuza ibicuruzwa by’Ubushinwa.
Ibitutu ku ruhande rw’ubusabe nabyo ni ingenzi cyane. Inzego nshya z’ingufu, harimo insinga za tungsten zikoresha amashanyarazi arenga 12%) n’ibikoresho bya nucleus fusion bikenera toni 3.000 za tungsten, byatumye ikoreshwa ry’amashanyarazi rirushaho kwiyongera mu buryo budasanzwe. Ubusabe bwa gisirikare nabwo bwariyongereye mu gihe cy’ibibazo bya politiki, mu gihe inganda zikora ibikoresho byo mu rwego rwo hejuru—nk’ibikoresho bya karubine by’ikoranabuhanga ku modoka zitwara amashanyarazi n’imashini zikora amarobo—byatumye habaho ikoreshwa ry’ibicuruzwa by’agaciro. Gukusanya amashanyarazi kw’abatanga ibikoresho byongera ubuke, aho ibiciro by’ifu ya tungsten byageze kuri yuan 364/kg bitarenze Kamena 2025. Nubwo hari impinduka mu isoko mu gihe gito, ubuke bw’igihe kirekire n’ububiko bw’ingamba za EU na Amerika bigaragaza ko byakomeje kwiyongera.

Bitewe n'impamvu z'izamuka ry'ibiciro bya karuboni ya tungsten, igiciro cy'uduce two gucukura cyarahinduwe. Niba utanze komande, nyamuneka gisha inama kugira ngo ubone igiciro gishya.
