Ocr21al4 Fecral Uila Kū'ē Pumehana Uea
ʻO OCr21Al4 kekahi ʻano mea maʻamau o Fe-Cr-Al alloy.
Loaʻa i ka FeCrAl alloy ka hiʻohiʻona o ka resistivity kiʻekiʻe, ka helu haʻahaʻa haʻahaʻa haʻahaʻa, ka mahana hana kiʻekiʻe, ka anti-oxidation maikaʻi a me ka anti-corrosion ma lalo o ke kiʻekiʻe wela.
Hoʻohana nui ʻia ia i ka umu ʻoihana, nā mea hana hale, ka umu ahi, ka metallurgy, nā mīkini, nā mokulele, nā kaʻa, ka pūʻali koa a me nā ʻoihana ʻē aʻe e hana ana i nā mea hoʻomehana a me nā mea kū'ē.

Ua hoʻohana nui ʻia e like me nā mea hoʻomehana i nā umu ahi a me nā kiln uila.
He ʻuʻuku ka ikaika wela ma mua o nā huila Tophet akā ʻoi aku ka kiʻekiʻe o ka helu heheʻe.
ʻO kā mākou lawelawe
1) E hele i ka palapala ISO9001 a me SGS.
2) Loaʻa nā laʻana.
3) lawelawe OEM.
4) E hāʻawi ʻia ka palapala hōʻoia o ka mea hana inā pono.
5) ʻO nā ala hoʻopili maikaʻi e mālama pono ai i nā waiwai.
6) E koho i ka mea hoʻouna palekana, wikiwiki, kumukūʻai no ka lawe ʻana i kā mākou mea kūʻai.
7) Ka manawa hāʻawi pōkole.
