4J46 Tsvimbo Inodzorwa Kuwedzera Alloy Bar Fe Ni Alloy yeGirazi uye Ceramic Chisimbiso

Tsanangudzo Pfupi:

Product Description

4J46 alloy rod is a Fe-Ni controlled expansion alloy ine inenge 46% nickel, yakagadzirirwa girazi-ku-metal uye ceramic-to-metal sealing applications. Kupisa kwayo kwekuwedzera kweiyo coefficient inoenderana neiyo yakaoma girazi uye ceramics, kuve nechokwadi yakanakisa hermetic chisimbiso uye kuvimbika.

Iyi alloy inoratidzira yakagadzikana yekuwedzera maitiro, yakanaka machinability, uye yakakwirira yekuisa chisimbiso kuita, ichiita kuti ishandiswe zvakanyanya mu semiconductor packaging, vacuum chubhu, relays, sensors, aerospace zvishandiso, uye chaiyo emagetsi zvikamu.
