Tungsten ea koporo
Lintlha tsa Sehlahisoa
Li-tag tsa Sehlahisoa
Ningbo De-Shin e fana ka mofuta o felletseng oa tungsten ea koporo (6 ~ 50wt.% Cu) bakeng sa likarolo tse fapaneng tsa ts'ebeliso ea indasteri. Ho nka ts'ebetso e tsoetseng pele ea ho kenella ka vacuum 'me lihlahisoa tsohle li kopana le litekanyetso tsa GB/T 8320-2003, ASTM B 702-93(Reapproved 2004). Copper tungsten ke pseudo-alloy mme e na le matla a ho hanyetsa a tungsten le conductivity e phahameng ea motlakase ea koporo.
Mokhoa oa tlhahiso:motsoako oa phofo -> tobetsa -> sintering -> ho kenella ha vacuum -> machining -> QC. Ts'ebetso ena eohle ea tlhahiso e laoloa ka thata ke QC ho netefatsa ts'ebetso ea boleng bo holimo.
Melemo:
1. Ho hanyetsa arc e phahameng ho kopantsoe le conductivity e ntle ea motlakase.
2. High mogote conductivity.
3. Katoloso e tlase ea mocheso.
Lisebelisoa:
1. Ho koala likhokahano le likhokahano tsa vaccum ho li-voltage tse phahameng le tse mahareng kapa li-interruptor.
2. Li-electrode tse ka har'a mochini o sehang khoholeho ea mobu ea motlakase.
3. Demo ea Sehlahisoa! Licheso tsa mocheso e le lintho tse pholisang feela tsa lisebelisoa tsa elektroniki le lisebelisoa tsa ho paka tsa elektroniki.
4. Electrodes bakeng sa ho hanyetsa welding.
Boholo ba thepa:
Molamu oa tungsten oa koporo: bophara≥0.5mm; bolelele ≤300mm.
Letlapa la tungsten ea koporo: botenya≥1.0mm; bolelele & bophara≤300mm.
