Tungsten ọla kọpa
Nkọwa ngwaahịa
Mkpado ngwaahịa
Ningbo De-Shin awade a zuru nso nke ọla kọpa tungsten (6 ~ 50wt.% Cu) dị iche iche ulo oru ngwa ubi. Ọ na-ewe usoro ntinye oghere oghere dị elu yana ngwaahịa niile na-ezuru oke GB/T 8320-2003, ASTM B 702-93 (2004 kwadoro). Tungsten ọla kọpa bụ pseudo-alloy na ọ na-ejide ikike nguzogide tungsten na eletriki eletrik dị elu nke ọla kọpa.
Usoro mmepụta:ntụ ntụ mix -> pịa -> sintering -> agụụ infiltration -> machining -> QC. Usoro mmepụta a niile bụ nke QC na-achịkwa nke ọma iji hụ na arụmọrụ kacha mma.
Uru:
1. Nnukwu arc na-eguzogide jikọtara ya na ezigbo ọkụ eletrik.
2. High thermal conductivity.
3. Mgbasawanye okpomọkụ dị ala.
Ngwa:
1. Arcing kọntaktị na vaccum kọntaktị na elu na ọkara voltaji breakers ma ọ bụ vaccum interruptors.
2. Electrodes na igwe na-egbu ọkụ ọkụ eletrik.
3. Ngosipụta ngwaahịa! Igwe ọkụ dị ka ihe na-ajụ oyi nke ngwaọrụ eletrọnịkị na ihe nkwakọ ngwaahịa eletrọnịkị.
4. Electrodes maka ịgbado ọkụ na-eguzogide.
Nha ngwaahịa:
Osisi tungsten ọla kọpa: dayameta≥0.5mm; ogologo ≤300mm.
Tungsten efere ọla kọpa: ọkpụrụkpụ≥1.0mm; ogologo & obosara≤300mm.
