Umkhwa wamaxabiso e-tungsten yaseTshayina uselele kubudlelwane phakathi kobonelelo kunye nemfuno.Lilonke, ukubuyiswa kwicala lemfuno kuyasilela ukuhlangabezana nolindelo lwemarike, amashishini asezantsi afuna amaxabiso aphantsi kwaye abarhwebi bathathe inyathelo lokujonga.Ngeenzuzo ezincitshisiweyo, imarike ye-tungsten inokuthi ibe phantsi kwixesha elifutshane.

Kwimarike yoxinaniso ye-tungsten, ubuthathaka kwicala lemfuno lucudisa inzuzo yamashishini emigodi kwaye intengiso yemithombo yobutyebi iphantsi koxinzelelo.Kwelinye icala, ukukhuselwa kokusingqongileyo, iindleko kunye nezinye izinto zonyusa isimo sengqondo esikhulayo sabavelisi;kwelinye icala, abangaphakathi basaxhalabile malunga necala letheminali elibuthathaka kunokuba nzima ukuxhasa imarike.

Kwimakethi ye-APT, imarike edikidiki yetheminali sesona sizathu siphambili sokuhla kwexabiso, kunye neempembelelo zokunqongophala kwemali kwisizini yesine, abathathi-nxaxheba bemarike babonisa imvakalelo exhalabileyo.Imakethi ye-tungsten powder nayo ihlala ibuthathaka ngenxa yembonakalo engacacanga yolindelo lwe-3C, i-auto kunye namanye amashishini.
