Khoom piav qhia:

4J28 hlau hlau, tseem hu uaFe-Ni hlau hlau, yog ib yam khoom siv sib nqus mos mos thiab iav-sealing. Nrog rau cov khoom sib xyaw ua ke feem ntau yog hlau thiab kwv yees li 28% nickel, nws muab kev nthuav dav thermal zoo heev nrog borosilicate iav, ua rau nws siv dav hauv kev ntim khoom hluav taws xob thiab iav-rau-hlau sealing daim ntawv thov.

4J28 hlauNws muaj cov yam ntxwv zoo heev rau kev sib khi, kev ua haujlwm sib nqus ruaj khov, thiab cov yam ntxwv txhim khu kev qha. Nws yog siv dav hauv cov raj hluav taws xob, cov khoom ntim hermetic, cov tsev semiconductor, thiab cov khoom siv aerospace thiab tub rog uas muaj kev ntseeg siab.
