Tsananguro pfupi:

Chiumbwa cheAlloy-4J29 (Chiumbwa chekuwedzera)
(Zita rakajairika: Kovar, Nilo K, KV-1, Dilver Po, Vacon 12)
Alloy-4J29 inozivikanwawo seKovar alloy. Yakagadzirwa kuti igutse chinodiwa chechisimbiso chegirazi chesimbi chakavimbika, chinodiwa mumidziyo yemagetsi yakaita sema light bulbs, vacuum tubes, cathode ray tubes, uye muma vacuum systems mu chemistry nedzimwe tsvakurudzo dzesainzi. Simbi zhinji hadzigone kuvhara girazi nekuti coefficient yavo yekuwedzera kwekupisa haina kufanana negirazi, saka sezvo joint ichitonhora mushure mekugadzirwa, kushushikana nekuda kwekuwedzera kwakasiyana kwegirazi nesimbi kunoita kuti joint itsemuke.
