Mitengo ya ferro tungsten ndi tungsten ufa ku China msika wa tungsten imakhalabe yosasintha kumayambiriro kwa sabata ino pamene malonda a msika amakhudzidwabe ndi kuperewera kwachuma komanso kufunikira kwachuma. Komanso, mitengo yatsopano yowongolera kuchokera ku mabungwe a tungsten ndi makampani omwe adalembedwa adasinthidwa pang'ono, kuthandizira milingo yamakono.

Kumbali yopereka, mabizinesi amigodi ayamba kupanga chimodzi pambuyo pa mnzake, koma zimatengera nthawi kuti awonjezere mphamvu zopanga. Kuchokera pamawonedwe a gulu loyamba la ma index onse owongolera migodi, kukula kwa mphamvu zopanga kumakhala kochepa. Komabe, amalonda alimbitsa malingaliro awo opeza phindu m'misika yaposachedwapa ya msika. Kuchulukitsa kwazinthu zapamalo kumafooketsa zotsatsa zolimba za zinthu za tungsten.

Kumbali yofunikira, kugulitsa m'makampani otsika mtengo mu February sikunali kwabwino, makamaka chifukwa chakuchepa kwakukula kwachuma pamsika womwe wakhudzidwa ndi mliriwu. Komabe, ndi kupewa komanso kuwongolera koyenera kwa coronavirus, komanso mfundo zadziko zothandizira mabizinesi, chidaliro chamsika chachira pang'onopang'ono. Makampaniwa amakhulupirira kuti chuma chamsika chikuyembekezeka kukwera kuti chikwaniritse zolinga ndi ntchito chaka chonse. Pakali pano, nkhawa kumbali yofunikira makamaka kuchokera ku msika wapadziko lonse lapansi, mliri wa mliri ku Japan, South Korea, Europe ndi United States, komanso kufalikira kwa chimfine.
