4J42 Qws Tswj Expansion Alloy Bar Fe Ni Precision Alloy Khoom

Lus piav qhia luv luv:

Product Description

4J42 alloy pas nrig yog Fe-Ni tswj kev nthuav dav hlau uas muaj txog 42% npib tsib xee. Nws nta cov kab hluav taws xob thermal expansion coefficient zoo sib xws ntawm cov iav nyuaj thiab ceramics, ua rau nws zoo tagnrho rau iav-rau-hlau thiab ceramic-rau-hlau sealing daim ntaub ntawv.

Cov alloy no muaj kev ruaj khov kev ua tau zoo, kev ua haujlwm zoo, thiab kev sib khi zoo heev, kev siv dav hauv cov khoom siv hluav taws xob, lub tshuab nqus tsev, thiab cov khoom siv dav hlau.
