Ningbo De-Shin inopa huwandu hwakazara hwemhangura tungsten (6 ~ 50wt.% Cu) kune dzakasiyana siyana maindasitiri ekushandisa.Zvinotora iyo yepamusoro vacuum infiltration process uye zvigadzirwa zvese zvinosangana nedanho reGB/T 8320-2003, ASTM B 702-93 (Yakabvumidzwa 2004).Copper tungsten ndeye pseudo-alloy uye inobata kupfeka kusaga kwe tungsten uye yakakwirira magetsi conductivity yemhangura.

Nzira yekugadzira:musanganiswa wehupfu -> dzvanya -> sintering -> vacuum infiltration -> machining -> QC.Ese aya maitiro ekugadzira anodzorwa zvakanyanya neQC kuve nechokwadi chekuita kwemhando yepamusoro.

Zvakanakira:

1. High arc resistance inosanganiswa nemagetsi ekugadzirisa zvakanaka.

2. High thermal conductivity.

3. Kuwedzera kwekushisa kwepasi.

Applications:

1. Arcing contacts uye vaccum contacts mune yakakwirira uye yepakati voltage breakers kana vaccum interruptors.

2. Electrodes mumagetsi spark erosion yekucheka michina.

3. Product Demo!Kupisa kunonyura sezvisina kutonhora zvinhu zvemagetsi zvishandiso uye zveElectroniki zvekurongedza zvinhu.

4. Electrodes for resistance welding.

Saizi yestock:

Copper tungsten tsvimbo: dhayamita≥0.5mm;kureba≤300mm.

Mhangura tungsten ndiro: ukobvu≥1.0mm;kureba & hupamhi≤300mm.
