Daga cikin karafa masu jujjuyawa, tungsten da tungsten alloys suna da mafi girman zafin canjin robobi.The roba gaggautsa zafin jiki canji na sintered da narke polycrystalline tungsten kayan ne game da 150 ~ 450 ℃, haifar da matsaloli a aiki da kuma amfani, yayin da na kristal tungsten guda daya ne m fiye da dakin zafin jiki.Rashin ƙazanta na tsaka-tsaki, microstructures da abubuwan haɗawa a cikin kayan tungsten, da sarrafa filastik da yanayin ƙasa, suna da babban tasiri akan zafin canjin filastik na kayan tungsten.Sai dai cewa rhenium na iya rage zafin canjin filastik na kayan tungsten, sauran abubuwan gami ba su da tasiri kaɗan akan rage zafin canjin filastik (duba ƙarfin ƙarfe).
Tungsten yana da mummunan juriya na iskar shaka.Halayensa na iskar oxygen suna kama da na molybdenum.Tungsten trioxide yana jujjuyawa sama da 1000 ℃, yana haifar da iskar shaka "mummunan".Don haka, kayan tungsten dole ne a kiyaye su ta hanyar vacuum ko inert yanayi lokacin amfani da su a babban zafin jiki.Idan an yi amfani da su a cikin yanayin iska mai zafi mai zafi, dole ne a ƙara suturar kariya.
Nadewa masana'antar makamai na soja
Tare da haɓakawa da ci gaban kimiyya, kayan gami na tungsten sun zama kayan da ake amfani da su don yin samfuran soja a yau, kamar harsashi, sulke da harsashi, kawunan harsashi, gurneti, bindigogin harbi, kawunan harsashi, motocin hana harsashi, tankuna masu sulke, jirgin sama na soja, manyan bindigogi. sassa, bindigogi, da dai sauransu. Makamin huda sulke da aka yi da gwanayen tungsten na iya keta sulke da sulke da babban kusurwar karkata, kuma shine babban makamin rigakafin tanki.
Tungsten Alloys sune abubuwan da suka danganci tungsten kuma sun ƙunshi wasu abubuwa.Daga cikin karafa, tungsten yana da wurin narkewa mafi girma, ƙarfin zafin jiki mai ƙarfi, juriya mai raɗaɗi, ƙarancin zafin jiki, ƙarancin wutar lantarki da aikin fitarwa na lantarki, waɗanda ke da matukar mahimmanci, sai dai babban adadin aikace-aikace a cikin kera simintin carbides da ƙari na gami.
Tungsten da alloys ana amfani da su sosai a masana'antar lantarki da hasken wutar lantarki, da kuma a cikin sararin samaniya, simintin gyare-gyare, makamai da sauran sassa don yin nozzles na roka, ƙirar simintin kashe-kashe, sulke mai huda harsashi, lambobin sadarwa, abubuwan dumama da zafi. garkuwa.
