Izintengo ze-tungsten carbide scrap yase-US zehle zafika ezingeni eliphansi kakhulu esikhathini esingaphezu kweminyaka eyishumi phakathi nokwehla kwezintengo ze-ammonium paratungstate (APT) kanye nenani elikhulu ngokomlando le-inventory ye-tungsten carbide.

Ukwehla kwezintengo ze-APT emasontweni asanda kwedlula akukhuthazi ukubizwa kabusha kwempahla egxilile kusukela kumfucumfucu we-tungsten carbide ngokunikeza impahla yokuphakelayo enenani eliphansi lemikhiqizo ye-tungsten.

Imakethe ye-carbide scrap yase-US iza kusukela esikhathini sokukhiqiza okuphezulu futhi ngenkathi isidingo siyancipha samathuluzi e-carbide. Ukwenyuka okukhulu kokungeniswa kwe-carbide kwamanye amazwe kukhulise i-inventory yasekhaya, kuyilapho izikhuthazo zezomnotho zokusebenzisa le mikhiqizo ziyancipha.

Izintengo ezimaphakathi zanyanga zonke zokuthekelisa ezivela e-China ze-APT ngoJulayi zifinyelele emazingeni aphansi phakathi neminyaka emibili ngo-$197-207/mtu. Izintengo zehle ngo-23pc ukusuka enanini elimaphakathi lanyanga zonke lika-$255-265/mtu ngoJanuwari 2019.

Amanani okuthenga amaphrosesa ase-US okufakwa kwezilahlwa ze-tungsten carbide namarawundi ehle aze afike ku-$5.00-6.00/lb ngo-August esuka ku-$7.25-8.25/lb ngenyanga ngaphambili. Ukwehla okungu-29pc kuphawula intengo ephansi kakhulu yomjikelezo we-carbide scrap kanye nokufakwa kusukela ekupheleni kukaJanuwari 2009.

Abacubunguli bathi i-carbide scrap ayiphinde isetshenziswe ku-APT ngamavolumu afanayo kuneminyaka edlule ngenxa yokuntuleka kwesidingo kubathengi basekhaya nabaphesheya kwezilwandle. impahla evela ku-carbide scrap ezothengiswa kabusha. Naphezu kwengcindezi evela ku-APT eshibhile engenisiwe, abathengi baphikisa ngokuthi ama-carbide scrap recyclers ngeke ayeke ukukhiqiza ukuze athenge i-APT esikhundleni sokucwenga izinsalela zezinto ezibonakalayo.
