Product Overview

4J33 alloy waya ndeye chaiyo yakaderera-yekuwedzera Fe-Ni-Co alloy zvinhu zvakagadzirirwa chaizvo hermetic girazi-kune-simbi sealing application. Iine inenge 33% nickel uye shoma shoma yecobalt, iyi alloy inopa kupisa kwekuwedzera coefficient yakanyatsoenderana negirazi rakaoma uye ceramics. Inoshandiswa zvakanyanya mukugadzirwa kwevacuum chubhu, infrared sensors, magetsi relays, uye mamwe madhizaini akavimbika.
