Mitengo ya tungsten yaku China idakhazikika pomwe nkhawa za Fanya stock zidapitilirabe pamsika. Mafakitole osungunula adakhalabe otsika kwambiri omwe amakhudzidwa ndi kuyang'anira chitetezo cha chilengedwe komanso mothandizidwa ndi kuchepa kwa mafakitale kuti mitengo ikhazikike. Tsopano msika wonse udakali chete pochita malonda.

Mumsika wokhazikika wa tungsten, mtengo wazinthu zomwe ogula amafunikira unali pafupi ndi mtengo wopangira, zomwe zimachepetsera phindu la mabizinesi amigodi kwambiri. Kuphatikiza apo, kuwunika kwachilengedwe, mvula yamkuntho komanso kutentha kwakukulu kunapangitsa kupanga kukhala kovuta. Chifukwa chake, ogulitsa sanali okonzeka kugulitsa zinthu poganizira kuchuluka kwazinthu. Koma kufunikira kofooka ndi kusowa kwachuma kunalimbikitsanso msika.

Pa msika wa ammonium paratungstate (APT), zinali zovuta kugula zopangira zotsika mtengo ndipo maoda ochokera kumtunda sanachuluke. Chifukwa chake, mafakitale osungunula sanagwire ntchito yopanga. Chifukwa cha nkhawa za masheya a Fanya, amalonda ambiri amakhala osamala.

Opanga ufa wa Tungsten sanali ndi chiyembekezo chokhudza momwe amaperekera mpikisano kuchokera kwa ogulitsa komanso kufuna mitengo yotsika ya amalonda. Mtengo wa ufa wa tungsten sunasinthidwe ndi zochitika zomwe zikuchitika pang'onopang'ono sabata yatha ndipo bizinesi inatha pakati pawo. Kufuna kufooketsa kosalekeza kungakhudze mitengo.
