hlau txhais
Hlau yog ib qho tseem ceeb ntawm ferrotungsten. Ntawm ferrotungsten, nws qhov tseem ceeb yog qhov thib ob tsuas yog tungsten. Lub atomic naj npawb ntawm cov hlau yog 26. Nyob rau hauv lub sij hawm ntawm lub ntsiab lus, hlau yog ib tug tshuaj nyob rau hauv kab 8 nrog atomic tooj 26. Hlau, ib tug kev hloov pauv hlau, yog lub thib plaub feem ntau lub caij nyob rau hauv lub ntiaj teb crust, accounting rau 5%. ntawm cov hlau; tsuas yog aluminium muaj ntau dua li hlau. Hlau kuj yog ib qho tseem ceeb ntawm lub ntiaj teb. Lub hauv paus ntawm lub ntiaj teb no tsuas yog tsim los ntawm hlau thiab npib tsib xee, thiab qhov tshwm sim ntawm lub ntiaj teb txav magnetic teb yog generated. Hlau kuj tau ua lub luag haujlwm tseem ceeb hauv keeb kwm, thiab tseem muaj lub sijhawm keeb kwm hu ua Iron Age.

Txhais ntawm tungsten
Tungsten yog qhov tseem ceeb tshaj plaws ntawm ferrotungsten. Tungsten yog cov khoom siv tshuaj nrog cov cim tshuaj W thiab atomic naj npawb 74. Raws li cov qauv txheej txheem, cov khoom siv tungsten yog cov hlau grey. Hauv ntiaj teb, tungsten tsuas tuaj yeem muaj nyob rau hauv daim ntawv ntawm cov tshuaj sib txuas. Ob hom tungsten tseem ceeb tshaj plaws yog tungsten dub thiab scheelite. Cov ntsiab lus ntshiab ntawm tungsten muaj lub cev muaj zog, tshwj xeeb tshaj yog cov ntsiab lus melting ntawm cov ntsiab lus tungsten yuav luag siab tshaj qhov melting point ntawm tag nrho cov elemental hlau, thib ob tsuas yog rau tag nrho cov ntsiab lus tom qab carbon. Tsis tas li ntawd, qhov siab ceev ntawm tungsten kuj yog ib qho tseem ceeb heev, nws qhov ceev yog 19.3 npaug ntawm cov dej. Qhov ntom ntom no me ntsis siab dua li ntawm uranium thiab 71% siab dua cov hlau lead. Tsis tas li ntawd, tungsten yog nkig thiab feem ntau muaj me me ntawm impurities, ua rau nws nyuaj rau kev ua haujlwm. Txawm li cas los xij, tungsten ntshiab heev yog tawv heev.
FeW alloy nqi
Ferrotungsten yog ib qho alloy ntawm hlau thiab tungsten, yog li nws muaj cov yam ntxwv ntawm cov hlau thiab tungsten.
