4J50 Qws Tswj Expansion Alloy Bar Fe Ni Precision Alloy Khoom

Lus piav qhia luv luv:

Product Description

4J50 alloy pas nrig yog Fe-Ni tswj kev nthuav dav hlau uas muaj txog 50% npib tsib xee.
Nws yog dav siv nyob rau hauv qhov chaw ruaj khov thiab tsis tshua muaj thermal expansion coefficient, tshwj xeeb tshaj yog rau kev sib khi nrog cov khoom siv ceramics thiab qee cov iav.

Lub alloy muab kev ua haujlwm zoo, weldability, thiab txhim khu kev qha sealing kev ua tau zoo, ua rau nws tsim nyog rau kev ntim khoom hluav taws xob, lub tshuab nqus tsev, thiab cov khoom siv dav hlau.
