ʻO nā metala āpau i ke ʻano maʻemaʻe, ʻo ka tungsten ke kiʻekiʻe o ka hālāwai (3410 degere, 6192oF), haʻahaʻa haʻahaʻa haʻahaʻa (ma nā mahana ma luna, 650 degere, 3000oF) a me ka ikaika tensile kiʻekiʻe. ʻO ia ka mea kūpono no ka wela kiʻekiʻe kiʻekiʻe a me nā noi vacuum kiʻekiʻe.
Loaʻa i ka Tungsten ka helu haʻahaʻa o ka hoʻonui wela (CTE) o nā metala maʻemaʻe ant, ʻo kona CTE kūpono me nā mea semiconductor, e like me, Si, GaN, GaAs,,
, a paʻa i ka wela kiʻekiʻe, e hoʻolilo iā ia i mea kūpono no ka hoʻopili uila a me nā sila.
He haʻahaʻa haʻahaʻa ka resistivity uila ʻo Tungsten ma mua o nā metala refractory ʻē aʻe, akā e hoʻonui ʻia me ka mahana, he mea koʻikoʻi kēia waiwai no nā noi wela wela.
He mea kupaianaha nō hoʻi kona mānoanoa kiʻekiʻe he 19.3 manawa ma mua o ka wai, ʻo Tungsten a me kona mau huila, W-Ni-Cu a i ʻole W-Ni-Fe he nui nā pono: kiʻekiʻe kiʻekiʻe (17.0-18.5g/
), ka machinability maikaʻi, ka modulus kiʻekiʻe o ka elasticity a me ka hiki ke komo kiʻekiʻe x-rays a me y-rays.

Nā noi
Hoʻohana nui ʻia nā huahana tungsten maʻemaʻe no nā ʻāpana kapuahi, Semiconductor Base Plate, Nā ʻāpana no ka Electron Beam Evaporation, Cathodes a me nā Anodes no ka hoʻokomo ʻana i nā lon, Tubes/Boats no ka Sintering of Capacitors, Targets for X-ray Diagnostics, Crucibles, Heating Elements, X-ray Radiation Targeting Shielding.
99.95 Hana ʻia ka Pepa Tungsten Maʻemaʻe ma ke kaomi ʻana a me ka sintering. Hoʻoponopono ʻia nā pepa āpau a hoʻouna ʻia me kahi palapala hōʻoia.
Hoʻopili kēia pepa tungsten maʻemaʻe i nā kūlana honua a loaʻa no ka hoʻouna koke ʻana, manuahi.
Kūlike ka Pepa Tungsten Maʻemaʻe i ka ASTM B760. He kūpono no nā hale kūʻai mīkini, noiʻi a me ka hoʻomohala ʻana, DIY'ers, a me nā labs.
ʻAno: Ka ʻili ʻili anu, ka ʻili holoi alkali
Noi: Ua kūpono ka pepa Tungsten no ka hana ʻana i nā ʻāpana implantation ion; Ke hana nei ka pepa Tungsten no ka hana ʻana i nā ʻāpana kumu kukui uila a me nā mea hoʻopihapiha uila; Ke hana nei ka pepa Tungsten no ka hana ʻana i ka moku tungsten, pale wela.
A me nā kino wela i ka umu wela kiʻekiʻe; hoʻohana ʻia no ka pahuhopu tungsten sputtering

E pili ana iā Zhuzhou Kingdon Industrial & Commercial Co., Ltd
Mai ko mākou hoʻokumu ʻana ma 2004, hoʻolaʻa mau mākou i ka hana ʻana i nā huahana tungsten kiʻekiʻe a me nā molybdenum. I kēia manawa ua hoʻolaha ʻia kā mākou ʻoihana kūʻai o waho ma USA, UK, Kelemānia, India, Kelemānia, Palakila, Polani, CZ, Slovenia, Singapore a me nā mea ʻē aʻe.
Lawelawe mea kūʻai mai
Hāʻawi ʻo Zhuzhou Kingdon Industrial & Commecial Co., Ltd i ka lawelawe maʻamau i kākoʻo ʻia e kā mākou ʻenehana. Eia kekahi, hiki iā mākou ke kōkua i ka mea kūʻai aku e koho i nā mea maka e like me ka appication o ka mea kūʻai. Hāʻawi mākou i ka lawelawe mea kūʻai aku 24/7.
No ke aha e koho ai iā mākou?
1. Loaʻa iā mākou nā mea hana kiʻekiʻe a me ka ʻenehana kiʻekiʻe.
2. Hiki iā mākou ke hāʻawi i nā huahana maʻamau no nā mea kūʻai. ʻO 1pc a i ʻole 1kg MOQ.
3. ʻO kā mākou ʻenehana makua a me ka lawelawe ʻoi aku ka maikaʻi e hāʻawi iā ʻoe i ka ʻeke nani a me ka lawe wikiwiki ʻana.
4. Hoʻohanohano nuiʻia mākou e nā mea kūʻai ma muli o kā mākou mau huahana maikaʻi a me nā kumukūʻai hoʻokūkū.
5. Loaʻa iā mākou ka lawelawe ma hope o -no ka hoʻololi.
FAQ
Inā he nīnau ʻē aʻe kāu, e ʻoluʻolu e kelepona mai iā mākou a hāʻawi mākou iā ʻoe i ka pane wikiwiki!
01. He aha kāu huahana nui?
