Hiriwa Tungsten
Taipitopito Hua
Tohu Hua
Kei te tuku a Ningbo De-Shin i te katoa o te tungsten hiriwa mo nga waahanga tono ahumahi rereke. E te reira i te tukanga marua infiltration matatau me hua katoa tutuki te paearu o GB/T8320-2003, ASTM B631.
Te tukanga whakaputa:te ranunga paura –> te pehi –> te sintering –> te kuhu korehau –> te miihini –> QC. Ko enei mahinga whakaputa katoa e tino whakahaerehia ana e QC kia pai ai te mahi o te kounga.
Painga:
1. Te kawe hiko teitei.
2. Te werawera teitei.
3. kiato High ki tino ōrite microstruction o rauemi.
Nga tono:
1. Nga kaikohikohiko.
2. Nga pakaru pakaru o te whenua.
3. He iti noa nga waahi ara iahiko.
4. ātete fehokotaki'anga hiko.
5. mau i te rakau parenga
