A matsayin ƙarfe mara ƙarfe, tungsten yana da ƙarfi da ƙarfi sosai.Saboda wannan 2.Main Features, tungsten carbide tare da tsayin daka mai ƙarfi da juriya mai ƙarfi an yi amfani da shi a cikin yankan kayan aiki da kayan aikin hakar ma'adinai a kan babban sikelin.
Tungsten shine ƙarfe mai jujjuyawa tare da mafi girman wurin narkewa.General karafa tare da wani narkewa batu sama da 1650 ℃ da wani ajiye da kuma wani narkewa batu mafi girma fiye da narke batu na zirconium (1852 ℃) ake kira refractory karafa.Abubuwan da aka saba da su sune tungsten, tantalum, molybdenum, niobium, hafnium, chromium, vanadium, zirconium, da titanium.A matsayin ƙarfe mai jujjuyawa, mafi mahimmancin fa'idar tungsten shine cewa yana da ƙarfin zafin jiki mai kyau da kuma juriya mai kyau ga narkakkar alkali da tururi.Yana bayyana kawai sama da 1000 ℃.Molybdenum da tungsten suna da kaddarorin kamanceceniya, fitaccen wurin tafasa da wutar lantarki, ƙaramin haɓakar haɓakar zafin jiki na madaidaiciya, da sauƙin sarrafawa fiye da tungsten.
Thermal conductivity na molybdenum karfe [135 watts / (m · bude)] aiki mafi kyau tare da takamaiman zafi [0.276 kJ / (kg · bude)], sanya shi zabi na halitta a kan thermal shock da thermal gajiya.Its narkewa batu ne 2620 ℃, sakandare zuwa tungsten da tantalum, amma da yawa ne da yawa m, don haka da takamaiman ƙarfi (ƙarfi / yawa) ne mafi girma fiye da tungsten, tantalum da sauran karafa, wanda shi ne mafi tasiri a aikace-aikace tare da m nauyi bukatun.Molybdenum har yanzu yana da babban ƙarfi a 1,200 ℃.
Babban Siffofin
Tungsten yana da babban wurin narkewa, ƙarancin tururi sosai, da ɗan ƙanƙara.Abubuwan sinadarai na tungsten suna da ƙarfi sosai, ba sa amsawa tare da iska da ruwa a cikin zafin jiki, wanda ba zai iya narkewa a cikin hydrochloric acid, sulfuric acid, nitric acid da alkali bayani.Narke cikin ruwan sarauta da cakuda nitric acid da hydrofluoric acid.A babban zafin jiki, yana iya haɗuwa da chlorine, bromine, iodine, carbon, nitrogen, sulfur, amma ba tare da hydrogenation ba.The tsarki tungsten narkewa batu ya kai 3410 ℃, wanda har yanzu yana da babban ƙarfi a game da 1300 ℃, yayin da tungsten tushen gami kuma yana da babban ƙarfi a game da 1800 ℃ kuma yana da kyau jure thermal tasiri.
Aikace-aikacen samfur
Saboda da high yawa na tungsten, High taurin, Saboda haka, shi ya zama manufa abu don yin high takamaiman nauyi gami, wadannan high takamaiman nauyi gami an raba zuwa W-Ni-Fe, W-Ni-Cu, W-Co, W-WC-Cu, W-Ag da sauran manyan jerin, Irin wannan gami yana da2.Main Featuress na high rabo, high ƙarfi, karfi sha radiation ikon, babban thermal watsin, kananan thermal fadada coefficient, mai kyau lantarki watsin, weldability da kyau processability, Ana amfani da ko'ina a cikin jirgin sama, jirgin sama, soja, mai hakowa, Electric kayan, magani da sauran masana'antu, Kamar masana'anta sulke, zafi nutse, sarrafa rudder ma'auni guduma da lamba kayan kamar wuka canza, kewaye mai watse, tabo walda lantarki, da dai sauransu.
Filin lantarki
Tungsten yana da ƙarfin filastik mai ƙarfi, ƙananan saurin evaporation, babban wuri mai narkewa da ƙarfin fitar da wutar lantarki mai ƙarfi, don haka tungsten da gaminsa ana amfani da su sosai a masana'antar lantarki da samar da wutar lantarki.Alal misali, tungsten waya yana da wani babban haske kudi da kuma dogon sabis rayuwa, don haka shi ne yadu amfani a yi na daban-daban kwan fitila filament, kamar incandescent fitila, aidin tungsten fitila, tungsten waya kuma za a iya amfani da a Manufacturing da kai tsaye zafi cathode da kuma Ƙofa na bututun oscillator na lantarki da kayan aikin lantarki iri-iri a cikin hita na cathode na gefe.The2.Main Featuress na tungsten ya sa ya dace da TIG waldi da sauran kayan lantarki don irin wannan aikin.
Masana'antar sinadarai
Ana amfani da mahadi na Tungsten a matsayin masu haɓakawa da launuka marasa ƙarfi, irin su tungsten disulfide ana amfani dashi azaman mai mai da mai haɓakawa a cikin gas ɗin roba, tungsten oxide na tagulla ana amfani dashi a cikin zane-zane, ana amfani da calcium ko magnesium tungsten sau da yawa a cikin phosphors.
Sauran yankunan
Domin tungsten yana kama da gilashin silicate na boryl, ana amfani da shi don yin gilashin gilashi ko karfe.Tungsten yana da ƙananan hankali kuma ana amfani dashi don yin babban kayan ado na tungsten na zinariya.Bugu da ƙari, ana kuma amfani da tungsten a cikin magungunan rediyo, kuma wasu kayan aikin za su yi amfani da wayar tungsten.
