Tuam Tshoj Vacon 12 Fe-Ni-Co iav Sealing Alloy Hlau Kovar Alloy Hlau Chaw Tsim Khoom thiab Hoobkas

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

Lus piav qhia luv luv:

Alloy-4J29 (Expansion alloy)
(Common Name: Kovar, Nilo K, KV-1, Dilver Po, Vacon 12)
Alloy-4J29 kuj hu ua Kovar alloy. nws tau tsim los ua kom tau raws li qhov yuav tsum tau muaj kev ruaj ntseg iav-rau-hlau foob, uas yuav tsum tau muaj nyob rau hauv cov khoom siv hluav taws xob xws li lub teeb qhov muag teev, lub tshuab nqus tsev, cathode ray tubes, thiab hauv lub tshuab nqus tsev hauv chemistry thiab lwm yam kev tshawb fawb tshawb fawb. Feem ntau cov hlau tsis tuaj yeem muab khi rau iav vim tias lawv cov coefficient ntawm thermal expansion tsis zoo ib yam li iav, yog li qhov sib koom ua ke txias tom qab tsim cov kev ntxhov siab vim qhov sib txawv ntawm qhov sib txawv ntawm cov iav thiab hlau ua rau kev sib koom ua ke.
