ʻO ka ʻauamo poepoe keleawe alumini C95400 ikaika kiʻekiʻe - Hoʻoheheʻe ʻia

ʻO ka Ni-Al Bronze Bar (C95800 / CuAl10Fe5Ni5-C) - Nā Kikoʻī Huahana ʻenehana

Hana ʻia ka mea ma o ka hoʻolei hoʻomau a i ʻole ka semi-continuous i ukali ʻia e ka extrusion wela multi-pass a me nā kaʻina hana huki/hoʻopau anu e hōʻoia i ka microstructure paʻa, ʻaʻohe porosity a me nā hoʻokomo ʻole metala, me ka nui o ka palaoa like. Hoʻomalu paʻa ʻia ka haku mele kemika i loko o ±0.15% no nā mea koʻikoʻi (Ni, Al, Fe) me ka hoʻokō piha ʻana me ASTM B148, EN 1982, a i ʻole GB/T 12225, me ka huina haumia ma lalo o 0.10%.

Ua hoʻokō ʻia ka mana o ka maikaʻi o ke kaʻina hana piha

● Hoʻoheheʻe ʻia i loko o ka umu hoʻokomo alapine waena me ka uhi flux a me ka pale argon; ʻo ka nui o ka oxygen <10 ppm;
● 100% hoʻāʻo ultrasonic o nā billets i hoʻolei ʻia (e like me ASTM B584 Class 1);
● Hoʻoheheʻe ʻekolu hopena + ka mālama wela ʻana ma hope o ka extrusion e hoʻomaikaʻi i ka hoʻolaha ʻana o ka pae α a me κ, e hoʻokō ana i ka paʻakikī mau HB180-240;
● Ua hoʻāʻo ʻia kēlā me kēia pūʻulu i ka tensile, impact, intergranular corrosion (ASTM G110), stress corrosion (ASTM G36/G44), me ka nānā ʻana o ke kolu o ka ʻaoʻao (SGS/Pony) a me ka palapala hōʻoia 3.1 e like me EN 10204.

Nā waiwai maʻamau (φ30-200 mm)

● Ikaika tensile ≥ 690 MPa
● Ikaika hāʻawi ≥ 330 MPa
● Elongation ≥ 12%
● Ka nui o ka palaho o ka wai kai ≤ 0.02 mm/makahiki (like me 40 makahiki)

Kūpono no nā mea hoʻohuli moana hana kaumaha, nā ʻau valve, nā ʻau pamu ikaika-pale i ka pala, a me nā ʻāpana kūkulu koʻikoʻi i hōʻike ʻia i ka wai kai i nā noi moana a me ke kai.

He loea mākou i ka hoʻolako ʻana i ke keleawe nickel-aluminium kiʻekiʻe a hiki ke huli piha ʻia i nā ʻoihana nui ma ke kūkulu moku, ka ʻoihana kaumaha, nā kahua kai, a me nā ʻāpana petrochemical. ʻO ka nui o ka ʻāpana he 50-300 tons, me ka hiki ke hana i nā ʻaelike lōʻihi e hōʻoiaʻiʻo ana i ka haku mele paʻa a me nā waiwai mechanical.
