Tuam Tshoj Vacon 12 Fe-Ni-Co Iav Sealing Alloy Hlau Kovar Alloy Hlau Tsim Khoom Thiab Hoobkas

Vacon 12 Fe-Ni-Co iav Sealing Alloy Hlau Kovar Alloy Hlau

Kev Piav Qhia Luv:

Cov hlau nplaum-4J29 (Cov hlau nplaum nthuav dav)
(Common Name: Kovar, Nilo K, KV-1, Dilver Po, Vacon 12)
Alloy-4J29 tseem hu ua Kovar alloy. nws tau tsim los ua kom tau raws li qhov xav tau rau lub foob iav-rau-hlau txhim khu kev qha, uas yog qhov xav tau hauv cov khoom siv hluav taws xob xws li lub teeb, cov raj nqus tsev, cov raj cathode ray, thiab hauv cov tshuab nqus tsev hauv chemistry thiab lwm yam kev tshawb fawb. Feem ntau cov hlau tsis tuaj yeem kaw rau iav vim tias lawv cov coefficient ntawm thermal expansion tsis zoo ib yam li iav, yog li thaum qhov sib koom ua ke txias tom qab tsim cov kev ntxhov siab vim qhov sib txawv ntawm cov iav thiab hlau ua rau qhov sib koom ua ke tawg.
