Product Overview

4J45 alloy wire is controlled thermal expansion Fe-Ni alloy inosanganisira inenge 45% nickel. Yakagadzirirwa maapplication anoda kugadzikana kwedimensional uye hermetic chisimbiso, kunyanya uko kuenderana kwekupisa negirazi kana ceramic kwakakosha. Ichi chinyorwa chakanakira kushandiswa mu semiconductor lead frames, sensor housings, uye yakakwirira-yakavimbika yemagetsi packaging.
