Copper Tungsten

Hāʻawi ʻo Ningbo De-Shin i ka nui o ka tungsten keleawe (6 ~ 50wt.% Cu) no nā ʻano noiʻi ʻoihana like ʻole. Lawe ʻo ia i ke kaʻina hana infiltration vacuum holomua a hoʻokō nā huahana āpau i ka criterion o GB/T 8320-2003, ASTM B 702-93 (Apono hou ʻia 2004). ʻO ka tungsten keleawe he pseudo-alloy a paʻa ia i ka hiki ke pale aku i ka tungsten a me ka conductivity uila kiʻekiʻe o ke keleawe.

Kaʻina hana:hui pauda -> kaomi -> hoʻopaʻa ʻia -> hoʻoheheʻe ʻana i ka lepo -> ka mīkini -> QC. Hoʻopili paʻa ʻia kēia kaʻina hana āpau e QC e hōʻoia i ka hana maikaʻi loa.

Pono:

1. Hoʻohui pū ʻia ke kūpaʻa arc kiʻekiʻe me ka conductivity uila maikaʻi.

2. Kiʻekiʻe thermal conductivity.

3. Hoʻonui wela haʻahaʻa.

Nā noi:

1. Hoʻokaʻawale i nā pilina a me nā mea hoʻopaʻa momi ma nā mea haʻihaʻi uila kiʻekiʻe a me waena a i ʻole nā ​​​​mea hoʻokaʻawale.

2. Electrodes i nā mīkini ʻoki uila.

3. Hōʻikeʻike Huahana! Heat sinks e like me nā mea hoʻoluʻu passive o nā mea uila a me nā mea hoʻopili uila.

4. Electrodes no ke kuʻi ʻana.

Nui waiwai:

Koʻokoʻo tungsten keleawe: diameter≥0.5mm; lōʻihi≤300mm.

Ke keleawe tungsten pā: thickness≥1.0mm; lōʻihi & laula≤300mm.
