Ningbo De-Shin na-enye ụdị ígwè tungsten ọla kọpa zuru oke (6~50wt.% Cu) maka ọrụ ụlọ ọrụ dị iche iche. Ọ na-ewe usoro ntinye oghere dị elu ma ngwaahịa niile na-emezu ihe achọrọ nke GB/T 8320-2003, ASTM B 702-93 (Ekwadoro ya ọzọ na 2004). Tungsten ọla kọpa bụ ihe a na-akpọ pseudo-alloy ma ọ na-ejide ikike iguzogide iyi nke tungsten na ike eletrik dị elu nke ọla kọpa.
Usoro mmepụta:Ngwakọta ntụ ntụ –> pịa –> sintering –> ntinye vacuum –> igwe eji arụ ọrụ –> QC. Usoro mmepụta a niile bụ nke QC na-achịkwa nke ọma iji hụ na arụmọrụ kacha mma.
Uru:
1. Nguzogide dị elu yana ezigbo njikwa eletriki.
2. Oke ike okpomọkụ.
3. Mgbasawanye okpomọkụ dị ala.
Ngwa:
1. Ịkpọ kọntaktị na kọntaktị vaccum n'ime ihe mgbawa voltaji dị elu na nke etiti ma ọ bụ ihe mgbochi vaccum.
2. Electrodes dị na igwe na-egbutu mbuze ọkụ eletrik.
3. Ngosipụta Ngwaahịa! Ebe a na-esi nri ọkụ dị ka ihe na-eme ka ihe dị jụụ nke ngwaọrụ eletrọniki na ihe eji echekwa ihe eletrọniki.
4. Electrodes maka ịgbado ọkụ.
Nha ngwaahịa:
Mkpanaka tungsten ọla kọpa: dayameta ≥0.5mm; ogologo ≤300mm
Efere tungsten ọla kọpa: ọkpụrụkpụ ≥1.0mm; ogologo na obosara ≤300mm.
