Wopanga Tungsten Powder
Mafotokozedwe Akatundu
Mawonekedwe a Spherical tungsten powder:
Kuchepa kwa okosijeni (<250 ppm)
High sphericity ndi digirii yozungulira (> 95%)
Kuchuluka kwamadzimadzi, palibe satellite kapena mpira wa agglomerates
Njira Yopangira Plasma ya ufa wa Spherical tungsten:
Wapadera kupatsidwa ulemu plasma ndondomeko akhoza kukhala oposa 20 mitundu zitsulo ndi ceramic zipangizo mu ozungulira ufa, kuphatikizapo tungsten, molybdenum, tantalum, niobium.
