Nyiaj tungsten
Product Detail
Khoom cim npe
Ningbo De-Shin muaj ntau yam nyiaj tungsten rau ntau daim ntawv thov kev lag luam. Nws yuav siv cov txheej txheem nqus nqus infiltration siab heev thiab tag nrho cov khoom ua tau raws li cov qauv ntawm GB / T8320-2003, ASTM B631.
Txheej txheem ntau lawm:hmoov mix -> nias -> sintering -> nqus infiltration -> machining -> QC. Tag nrho cov txheej txheem ntau lawm yog nruj me ntsis tswj los ntawm QC kom ntseeg tau tias kev ua tau zoo tshaj plaws.
Qhov zoo:
1. Muaj hluav taws xob conductivity.
2. High thermal conductivity.
3. High density nrog zoo meej uniformity microstruction ntawm cov khoom.
Daim ntawv thov:
1. Circuit Court breakers.
2. Lub ntiaj teb leakage breakers.
3. Tej yam me me Circuit Court breakers.
