Nā pāʻālua Fe-Cr-Al

Hōʻike Pōkole:

ʻO nā pāpālua ʻo Fe-Cr-Al kekahi o nā mea uila electrothermal i hoʻohana ākea ʻia ma ka home a me nā ʻāina ʻē. Hoʻohālikelike ʻia ia e ke kūpaʻa kiʻekiʻe, ka liʻiliʻi liʻiliʻi o ke anuanu coefficient, ke kūpikipiki maikaʻi maikaʻi, ke kiʻekiʻe wela a pēlā aku. Hoʻohana ākea kēia mau mea hoʻohui i ka hana ʻana i nā lakohana hoʻomehana hanahana a me nā mīkini pono hoʻomehana hale.

Hoʻokaʻawale ʻia nā mea a pau kūpale e hoʻomohala ʻia e kā mākou ʻoihana e ka hoʻohui like ʻana, ke kiʻekiʻe kiʻekiʻe, ke ana pololei, ke ola hana lōʻihi a me ka hana maikaʻi. Hiki i nā mea kūʻai ke koho i ka papa kūpono e like me nā koi ʻokoʻa.

Ua loaʻa iā SG-GITANE'S resisting heat wire 0Cr25Al5 ke poʻo inoa o ka huahana maikaʻi loa mai ka China Ministry of Metallurgical Industry. I ka makahiki 1983, ua hāʻawi ʻia ka uwea paio kūʻē ʻo HRE i ka makana helu ʻelua no ka holomua o ka ʻepekema a me ka ʻenehana mai ke Kaona ʻo Beijing.
