Ndodo ya aloyi ya 4J29, yomwe imadziwikanso kuti ndodo ya Kovar, ndi aloyi yowonjezera yolamulidwa ndi Fe-Ni-Co yokhala ndi coefficient ya kutentha yofanana kwambiri ndi ya galasi lolimba ndi zoumba. Imapereka mphamvu zabwino kwambiri zotsekera kuchokera kugalasi kupita kuchitsulo ndi ceramic kupita kuchitsulo, zomwe zimaonetsetsa kuti kutentha kwake kuli kotetezeka.

Ndi makina okhazikika, makina abwino, komanso kudalirika kotseka, ndodo za 4J29 zimagwiritsidwa ntchito kwambiri mu ma CD amagetsi, zida zotsukira mpweya, maziko a semiconductor, masensa, ndi zida zoyendera ndege.
