I ka ʻāina o nā alumini alumini ʻoihana,6061 T6 mau paipu aluminima ke ʻano he hopena maʻalahi, hana kiʻekiʻe no nā ʻāpana mai ka aerospace a i nā mīkini kaumaha. Ma keʻano he alakaʻi alakaʻi o nā alumini extrusions a me nā lawelawe mīkini kikoʻī, ʻike mākou ʻo 6061-T6 ka hui kūʻokoʻa o ka ikaika, ka pale ʻana i ka corrosion, a me ka hana hana i mea koho nui no nā mea ʻenekinia a me nā hui kūʻai e ʻimi nei i ka hilinaʻi a me ka maikaʻi. Hoʻokaʻawale kēia ʻatikala i kāna haku mele mele, ʻenehana a me nā waiwai kino, a me nā noi honua maoli-e hoʻolako iā ʻoe e hoʻoholo i nā hoʻoholo no kāu papahana e hiki mai ana.

1. Ka Hui Kemika: Ke Kumu o ka Hana 6061-T6

Hoʻokaʻawale ʻia ʻo 6061 ma ke ʻano he Al-Mg-Si-Cu alloy, ʻāpana o ka 6000 series o nā alumini alumini i ʻike ʻia no ko lākou hiki ke hoʻoikaika i ka ua. Hōʻike ka inoa "T6" i kahi kaʻina hana hoʻomaʻamaʻa wela (ka hoʻopili ʻana i ka hopena a ukali ʻia e ka ʻelemakule hana), akā hoʻomaka ka hana kumu o ka alloy me kāna hana hoʻonaninani kemika. No ka ASTM B241 (ka maʻamau no ka alumini a me ka alumini alumini seamless tubing), 6061-T6 alumini paipu i loaʻa i kēia mau mea nui (ma ke kaumaha):

- Aluminum (Al): 95.8%–98.6%: ʻO ka metala kumu, hāʻawi i nā hiʻohiʻona māmā a me kahi matrix paʻa no nā mea hoʻohui.

- Magnesium (Mg): 0.8%–1.2%: ʻO ka mea hoʻoikaika mua, e hoʻopili me ke silikoni e hana i nā pūhui intermetallic Mg₂Si—ke kuamoʻo o ka ikaika kiʻekiʻe o 6061-T6.

- Silika (Si): 0.4%–0.8%: Hana pū me ka magnesium e hiki ai i ka paʻakikī o ka ua; Ua kaulike kona ho'oku'u 'ana i mea e pale aku ai i nā māhele ha'iha'i e hiki ke ho'ololi i ka ductility.

- Copper (Cu): 0.15%–0.40%: Hoʻonui i ka ikaika tensile a hoʻomaikaʻi i ka pane ʻana i ka mālama ʻana i ka wela, ʻoiai e hoʻoikaika ana i ka pale ʻana i ka lole no nā noi e pili ana i ka friction a i ʻole ke kaumaha mechanical.

- Manganese (Mn): 0.15% Max: Hoʻomaʻemaʻe i ke ʻano o ka palaoa o ka alloy, e hōʻemi ana i ka maʻalahi i ka haki ʻana i ka wā e hana ana a hoʻomaikaʻi i ka paʻa o ka nui.

- Chromium (Cr): 0.04%–0.35%: Hoʻopaʻa i ka ulu ʻana o ka palaoa i ka wā e mālama ai i ka wela, hoʻonui i ka pale ʻana i ka corrosion (ʻoi loa i loko o nā kaiapuni moana a i ʻole nā ​​​​māmā), a pale i ka corrosion intergranular.

- Hao (Fe): 0.7% Max: He mea koena i hoʻomalu ʻia e hōʻemi i ka hoʻokumu ʻana o nā mea haumia Fe-Al-Si, hiki ke hoʻonāwaliwali i ka huila a hoʻohaʻahaʻa i ka pau ʻana o ka ʻili.

ʻAʻole kūʻokoʻa kēia haku: ʻoi aku ka maikaʻi o kēlā me kēia mea e hoʻohālikelike i ka ikaika, ductility, a me ka pale ʻana i ka corrosion - e hoʻoponopono ana i nā wahi ʻeha maʻamau i nā noi paipu ʻoihana, e like me ka hāʻule mua ʻana ma lalo o ka ukana a i ʻole ka hoʻohaʻahaʻa ʻana i nā kūlana paʻakikī.

2. Nā waiwai nui: No ke aha i ʻoi aku ai ka 6061-T6 Aluminum Tubing i nā mea ʻē aʻe.

ʻO ke kaʻina hana lapaʻau wela T6 (maʻamau 530 ° C no ka annealing solution, a ukali ʻia e ke kinai ʻana i ka wai a me ka ʻelemakule ma 120 ° C no 16 mau hola) wehe i ka mana piha o 6061, e loaʻa ana i nā waiwai i kūpono no nā kaiapuni koi. Aia ma lalo iho kahi kikoʻī kikoʻī o kāna metric hana koʻikoʻi:

2.1 Pono Mechanical

ʻO ka hana mīkini kahi e ʻālohilohi ai ka 6061-T6, e hāʻawi ana i kahi lākiō ikaika-a-kaumaha ʻoi aku ka maikaʻi ma mua o ke kila a i ʻole nā ​​mea alumini alumini ʻē aʻe e like me 6063. No nā kūlana ʻoihana (e laʻa, ASTM B241 a me EN 573-3),6061-T6 paipu alumininā hōʻike:

- Ka ikaika o ka hua (σ₀.2): ≥276 MPa: ʻO ke koʻikoʻi kahi e hoʻomaka ai ka hoʻoheheʻe mau ʻana o ka mea waiwai - ʻoi aku ka kiʻekiʻe ma mua o 6063-T6 (≈215 MPa), kūpono ia no nā noi lawe ukana.

- Ka ikaika Tensile (σᵤ): ≥310 MPa: ʻO ke koʻikoʻi kiʻekiʻe i hiki i ka paipu ke kū ma mua o ka haki ʻana, e hōʻoiaʻiʻo ana i ka paʻa i nā hiʻohiʻona kiʻekiʻe a i ʻole nā ​​​​kaumaha (e laʻa, nā laina hydraulic).

- Elongation at Break (δ₅₀): ≥10%: He ana o ka ductility, e hōʻike ana i ka paipu hiki ke kikoo ʻole me ka haki ʻole—koʻikoʻi no ka hana ʻana i nā kaʻina hana e like me ke kulou a i ʻole ka lapalapa ʻana.

- Brinell Hardness (HB): ≥95: Hāʻawi i ke kū'ē i ka indentation a me ka lole, e ho'ēmi ana i nā pono mālama i nā noi e pili ana i ka pilina me nā mea'ē aʻe.

Ke hana nei kēia mau waiwai i ka 6061-T6 he "workhorse" alloy: ua lawa ka ikaika e hoʻololi i ke kila i nā papahana māmā (ʻoki i ke kaumaha a hiki i ka 30% vs. kila māmā) ʻoiai ke koena ductile lawa no ka machining precision-kahi pōmaikaʻi nui no kā mākou mea kūʻai aku e koi ana i nā paipu i hoʻopili pono ʻia.

2.2 Nā ʻano kino a me ka ʻino

Ma waho aʻe o ka mechanics, hoʻonui nā ʻano kino o 6061-T6 i kona hoʻohana ʻana ma nā ʻoihana:

- Māmā: 2.70 g/cm³: Ma kahi o hoʻokahi hapakolu ka mānoanoa o ke kila, e hōʻemi ana i ke kaumaha o nā mea holoʻokoʻa no ka aerospace, automotive, a me nā lako lawe lima.

- Ka Hoʻokele Thermal: 151 W/(m·K): ʻO ka hoʻoili wela maikaʻi, kūpono ia no nā ʻōnaehana hoʻomaha, nā mea hoʻololi wela, a me nā pā uila.

- Elele uila: 43% IACS: ʻOi aku ka haʻahaʻa ma mua o ka alumini maʻemaʻe akā lawa no ka hoʻokumu uila a me nā noi haʻahaʻa.

Ma ke ʻano o ka pale ʻana i ka corrosion, hana maikaʻi ʻo 6061-T6 i ka lewa, ka wai maʻemaʻe, a me nā wahi kemika māmā (e laʻa, nā mea hoʻoluʻu ʻoihana). ʻOiai ʻoi aku ka liʻiliʻi o kāna ʻano keleawe i ka corrosion ma mua o 6063, hiki ke hoʻēmi ʻia kēia me ka mālama ʻana i ka ʻili e like me ka anodizing (ka hana ʻana i kahi paʻa paʻa, pale oxide) a i ʻole nā ​​​​lawelawe uhi pauka-nā lawelawe a mākou e hāʻawi ai e hoʻomaikaʻi i ka hana paipu o kā mākou mea kūʻai aku.

2.3 Machinability a me ka hana

Kaulana ʻo 6061-T6 no kona machinability maikaʻi loa, he mea koʻikoʻi koʻikoʻi no kā mākou hana ʻenehana pololei i loko o ka hale. ʻO kona ʻano palaoa maikaʻi a me ka paʻakikī like ʻole e hiki ai ke:

- ʻO ka wikiwiki ʻoki kiʻekiʻe: E hōʻemi ana i ka manawa hana no nā ʻāpana maʻamau (e laʻa, nā wēlau i hoʻopaʻa ʻia, nā flanges, a i ʻole nā ​​lua i kālai ʻia).

- Hoʻopau ʻia ka ʻili maʻemaʻe: E hōʻemi ana i ka poli ma hope o ka mīkini a hoʻomaikaʻi i ka hoʻopiʻi nani no nā ʻāpana ʻike ʻia.

- Hoʻohālikelike me nā kaʻina hana mīkini maʻamau: Me ka huli ʻana o CNC, wili, wili, a me ka paʻi ʻana-ʻaʻole pono nā lako kūikawā.

Hāʻawi ia i ka weldability maikaʻi (me ka hoʻohana ʻana i ka TIG a i ʻole MIG welding me 4043 filler metal) a me ke ʻano anuanu maʻamau, ʻoiai pono e hana ʻia ma mua o ka wela T6 e pale aku ai i ka haki. No nā mea kūʻai e makemake ana i nā paipu kūlou a i ʻole ke ʻano, hāʻawi mākou i ka hana mua (T4) a ukali ʻia e ka ʻelemakule T6 e hoʻomau i ka ikaika.
