KOVAR Nickel Alloy
KOVAR （4J29） ni icyuma - nikel - cobalt alloy yo mu bwoko bwa Kovar. Bitewe na coefficente yo kwagura ubushyuhe hafi yikirahure gikomeye (nkikirahuri cya borosilike), irashobora kugera kumurongo mwinshi wikirahure hagati yikirahure nicyuma, kandi nikintu cyibanze mubice nko gupakira ibikoresho bya elegitoroniki nibikoresho bya vacuum.
