Tooj tungsten

Ningbo De-Shin muaj ntau yam ntawm tooj liab tungsten (6 ~ 50wt.% Cu) 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 GB / T 8320-2003, ASTM B 702-93 (Reapproved 2004).Tooj liab tungsten yog pseudo-alloy thiab nws tuav cov hnav tsis kam muaj peev xwm ntawm tungsten thiab siab hluav taws xob conductivity ntawm tooj liab.

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. High arc kuj ua ke nrog zoo hluav taws xob conductivity.

2. High thermal conductivity.

3. Tsawg thermal expansion.

Daim ntawv thov:

1. Arcing contacts thiab vaccum contacts in high and medium voltage breakers or vaccum interruptors.

2. Electrodes nyob rau hauv hluav taws xob hluav taws xob yaig tej tshuab.

3. Khoom Demo!Cov dab dej kub ua kom txias txias ntawm cov khoom siv hluav taws xob thiab cov khoom ntim khoom siv hluav taws xob.

4. Electrodes rau welding kuj.

Tshuag loj:

Copper tungsten pas nrig: diameter≥0.5mm;ntev ≤300mm.

Copper tungsten phaj: thickness≥1.0mm;ntev & dav ≤300mm.
