Hlau Nickel Cobalt Alloy
Covalloy yog lub tshuab nqus tsev melted, hlau-nickel-cobalt alloy uas tau siv dav hauv kev lag luam hluav taws xob. Kovar yog nickel-hlau-cobalt, tswj-expansion alloy uas muaj 29% npib tsib xee. Nws coefficient ntawm expansion, uas txo nrog nce kub mus rau qhov inflection point, phim tus nqi expansion ntawm borosilicate iav thiab alumina ceramics.
Kovar alloy tau siv los ua hermetic ntsaws ruaj ruaj nrog lub zog Pyrex tsom iav thiab cov ntaub ntawv ceramic. Cov hlau no tau pom dav siv hauv cov raj fais fab, microwave tubes, transistors, thiab diodes. Hauv kev sib xyaw ua ke, nws tau siv rau lub pob tiaj tus thiab cov pob khoom dual-hauv-kab.
