Mayelana ne-Tungsten Metal
UTungsten uluhlobo lwezinto zensimbi. Uphawu lwayo lwento "W"; Inombolo yayo yokulandelana kwe-atomic ingu-74 kanti isisindo sayo se-athomu singu-183.84. Kumhlophe, kunzima kakhulu futhi kunzima. Kungokwamndeni we-chromium futhi kunezinto ezizinzile zamakhemikhali. Uhlelo lwalo lwe-Crystal lwenzeka njengesakhiwo se-cubic crystal sakhiwo (BCC). Iphuzu layo elincibilikayo licishe libe ngu-3400 ℃ futhi iphuzu layo elibilayo lingaphezu kuka-5000 ℃. Isisindo saso singu-19.3. Kuluhlobo lwensimbi engavamile.

【Abanye】 I-Alloys enobumbano olwengeziwe, iTungsten Alloy kufaka phakathi i-oxides, kanye ne-tungsten-molybdenum alloy njll.Kutholakala.Sicela uxhumane nathi ngemininingwane.
Yini induku ye-tungsten esetshenziselwa?
Induku ye-tungsten, Ukuba nephuzu eliphakeme elibi, kusetshenziswa ezinkambeni eziningi zezimboni ngenxa yokumelana kwazo okushisa kakhulu okushisa. Isetshenziselwa i-Filament kagesi ye-Bulbs, ama-electrodes we-stronic-lamp, izingxenye ze-bulb ze-elekthronikhi, ama-electrodes we-welding, izinto zokushisa, njll.

Yini i-tungsten powder esetshenziselwa?
UTungsten Powderisetshenziswa njengento eluhlaza ye-super-hard alloy, imikhiqizo ye-powder metallurgy efana nendawo yokuxhumana ye-welding kanye nezinye izinhlobo ze-alloy. Ngaphezu kwalokho, ngenxa yezidingo eziqinile zenkampani yethu mayelana nokuphathwa kwekhwalithi, singanikeza kakhulu i-tungsten powder enobumsulwa ngaphezulu kwama-99.99%.
