Tsaurin karafa - wani bayyani

Kullum, muna magana a kan "tsaurin karafa" za a fahimci cewa wadannan su ne karafa da cewa suna da matukar high narkewa zafin jiki, da ya kai gare shi 4000 ° C. Molybdenum, Tantalite, tungsten, niobium da rhenium - asali tsaurin karafa. Har ila yau, wannan jerin za a iya kara, da sauransu - chromium, vanadium, osmium, hafnium, kuma zirconium karafa, da narkewa zafin jiki ya kai 2123 ° C.

Tsaurin karafa ne mai ban sha'awa domin dũkiyõyinsu. Saboda haka, misali, Manuniya na molybdenum da tungsten taurin dama da amfani da wadannan karafa domin zafi magani na kayan karkashin injin. Products sanya wasu tsaurin karafa da musamman Properties, msl, tungsten filaments kiyaye filament zafin jiki zuwa 3073 ° C.

Amma da juriya da tsaurin karafa za a iya dangana ga babban rashin. Contact tare da oxygen muhimmanci musababin a kan thermal kaddarorin tsaurin karafa. Wannan shi ne dalilin yin amfani da karafa a cikin wannan kungiyar - a cikin wani yanayi inda za su iya a gaba daya ware daga cikin iska.

Tungsten - tushen tsaurin karafa a metallurgy

Tungsten ne daya daga cikin mafi tsaurin karafa. Da narkewa batu na tungsten ne mafi girma fiye da sauran, tungsten - m karfe, yana yiwuwa ya zana lafiya zaren, an kuma daidai weldable.

Amma da shahararsa shi ne ba na baya zuwa karfe kasa rare karafa.

A amfani da tungsten

Ƙarfe tungsten amfani Manufacturing filament yarns, wanda ake amfani da shi a lighting na'urorin kamar yadda wani dumama kashi - a injin Tanderu juriya. A high yawa daga tungsten damar yin amfani da wannan karfe mai counterweight for daban-daban projectiles. Kamar yadda tungsten lantarki amfani a lokacin TIG waldi. A m gami da tungsten carbide ana amfani da filler.

Tungsten kamar yadda molybdenum, da Tantalite da ake amfani da matsayin mai mulkin a cikin gami, wanda ake amfani da su a sassa na sarari fasahar nukiliya. Da ikon yin tsayayya sosai high yanayin zafi - babban manufa ga abin da wadannan gami aka halicce su.
