Nā Extrusions Alumini Series 6000: He ʻIke Holoʻokoʻa

Ua lilo ka ʻohana hui alumini moʻo 6000 i hoʻokahi o nā ʻōnaehana mea i hilinaʻi nui ʻia ma nā noi ʻoihana hou. Me ka magnesium a me ka silicon ma ke ʻano he mau mea hui nui, hāʻawi kēia ʻohana i kahi hui paʻa o ka ikaika mechanical, ke kūpaʻa i ka pala, a me ka hana e lilo ai ia i koho no nā extrusions o nā ʻano āpau.

ʻO ka haku mele a me nā papa Alloying nui

ʻO ka ʻohana moʻo 6000 he mau mea hoʻohuihui alumini e loaʻa ana ma kahi o 0.4% a 1.5% magnesium a me silicon, e hui pū ana e hana i ka pae hoʻoikaika Mg₂Si. Hāʻawi kēia hui iā ʻoe i kahi mea e kaulike ana i ka ikaika kūpono me ka hiki ke hoʻohālikelike maikaʻi loa a me ke kūpaʻa ʻana i ka pala.

6061 ʻo ia ke koho kaulana loa ma kēia ʻohana. E loaʻa iā ʻoe ma nā wahi āpau—mai nā ʻāpana kūkulu a hiki i nā ʻāpana hoʻonaninani. Hoʻonui ka hoʻohui ʻana o ka chromium i kona kūpaʻa ʻana i ka haki ʻana o ka corrosion stress. I loko o ka mahana T6, hoʻokō ia i nā waiwai ikaika tensile ma kahi o 240-310 MPa, ʻo ia ka mea e ʻoi aku ai ma mua o ka lawa no ka hana hāpai ukana. Hana maikaʻi ia i nā mīkini a kū i ka anodizing a me ka uhi pauka me ka ʻole o nā poʻo poʻo.

6063 ʻo ia ka lio hana extrusion maoli. Hoʻolālā kūikawā ʻia no nā ʻano paʻakikī, ʻo kona haʻahaʻa magnesium a me ka silicon content ʻo ia hoʻi e extrudes nani ia, e ʻae ana i nā paia lahilahi a me nā kikoʻī paʻa. Aia ka ikaika tensile ma ka pae 170-240 MPa no nā mahana T5 a me T6. Inā makemake ʻoe i ka paʻakikī a me ka pololei i kāu ʻaoʻao, hoʻopau ʻo 6063 i ka hana.

6005 aia ma waenakonu o ka pūʻolo. Hāʻawi ia iā ʻoe i ka ikaika ma kahi o 245-310 MPa ma T6 ʻoiai e hoʻopuka maikaʻi ana, a ua lilo ia i mea kaulana loa ma nā mākeke ʻEulopa a me ʻAsia.

6082 ʻo ia ka mea paʻakikī o ka ʻohana. Hāʻawi ia i ka ikaika tensile ma ka pae 290-360 MPa ma T6, e lilo ia i mea e pono ai ke pono ʻoe i ka ikaika maoli. ʻO ka ʻoiaʻiʻo ua ʻoi aku kona maikaʻi ma mua o ke kila palupalu ma ke kumu ikaika-a-kaumaha ua hoʻonui nui ʻia kona kaulana i ke kūkulu ʻana o kēia au.

Na Pono Kino a me Mekanika

ʻO ka ikaika tensile ma waena o ka pae 6-series e holo ana mai kahi o 170 MPa no 6063 i hoʻopaʻa kūlohelohe ʻia a hiki i 360 MPa no ka ikaika kiʻekiʻe 6082-T6. ʻO ka ikaika huahua maʻamau e hele mai ma kahi o 60% a 70% o ka waiwai tensile hope loa, no laila e hāʻawi ʻo 6061-T6 iā ʻoe i nā ikaika huahua e lana ana ma waena o 180-210 MPa.

ʻO ka maʻamau, ʻo nā waiwai elongation i ke kūlana T6 e pae ma waena o 8% a me 12%. He mea nui kēia ductility i mālama ʻia—ʻo ia ka mea e pale ai i kāu mau ʻāpana mai ka lilo ʻana i mea palupalu i nā noi me ka haʻalulu a i ʻole ka hopena. ʻOi aku ka maikaʻi o nā alloys 6-series ma aneʻi ma mua o ka hapa nui o nā ʻohana alumini hiki ke mālama ʻia i ka wela, ʻo ia kekahi kumu e hoʻāʻo pinepine ai nā mea hoʻolālā iā lākou.

Loaʻa i nā hui 6-series āpau ka nui like o ka nui ma kahi o 2.70 g/cm³, ʻoi aku ka māmā ma mua o ke kila ma 7.85 g/cm³. ʻO ka conductivity thermal e holo ana ma 150-170 W/m·K, a ʻo ke coefficient o ka hoʻonui linear e noho ana ma kahi o 23.6 × 10⁻⁶/K—he mea nui e hoʻomanaʻo inā ʻoe e kāwili ana i nā mea a i ʻole e hana ana me nā loli o ka mahana.

ʻO ke kūpaʻa ʻana i ka palaho kekahi o nā mea ikaika o kēia ʻohana. ʻO ka papa oxide kūlohelohe i hui pū ʻia me ke ʻano o ka hana kemika a ka magnesium a me ka silicon, e hana ana i kahi kiʻiʻoniʻoni passive e paʻa a ho'ōla ponoʻī. Ma nā wahi kai, nā wahi kahakai, a me nā wahi ʻoihana, paʻa wale kēia mau mea hao me ka ʻole o ka mālama nui ʻana. E hoʻohui i kekahi anodizing ma luna a ke nānā nei ʻoe i ka pale ʻana i ka palaho e kū pono ana i ka pōkā no ka hapa nui o nā hoʻohana.

Nā Kūlana o ka Wela

He mea nui ka loaʻa ʻana o ke ʻano kūpono. ʻO ke ʻano o T4, ʻo ia ka hoʻomehana ʻia ʻana o ka hopena a hoʻomākua maoli ʻia—loaʻa iā ʻoe ka ikaika waena me ka ductility maikaʻi loa. Hoʻomākua ʻia ʻo T5 me ka ʻole o ka hoʻoponopono ʻana i ka hopena, e hāʻawi ana iā ʻoe i ka ikaika paʻa a me ke kūpaʻa maikaʻi o ka dimensional. ʻO T6 ka spec maʻamau—hoʻomehana ʻia ka hopena, a laila hoʻomākua ʻia e ka hana a hiki i ka ikaika kiʻekiʻe, e koi pinepine ana i 12-18 mau hola ma ka mahana kiʻekiʻe.

Hōʻike ʻo T6A i kahi mana i hoʻonui ʻia me nā kaohi kaʻina hana paʻa, e hāʻawi ana i ke kūlike maikaʻi a me nā waiwai mechanical i hoʻomaikaʻi ʻia no nā noi koʻikoʻi.

Nā noi ʻenehana

Ke kūkulu ʻana a me ke kūkulu ʻanaNā mōlina puka makani, ʻōnaehana pā pale, a me nā lālā kūkulu—ʻo 6063-T5 a me 6061-T6 ke kumu o kēia mākeke. ʻO ka hui pū ʻana o ka ikaika kūpono, ke kūpaʻa ʻana i ka pala, a me ke ʻano maikaʻi e hoʻolilo iā lākou i mea maʻamau no nā papahana noho a me nā ʻoihana.

Kaʻa a me ka lawe ʻanaKe hoʻoikaika nui nei nā mea hana kaʻa i ka 6061-T6 a me 6082-T6 i nā ʻāpana kūkulu, nā pale, a me nā noi hoʻoheheʻe wela. Hoʻololi pololei ka mālama ʻana i ke kaumaha i ka hoʻokele waiwai wahie maikaʻi aʻe, a hoʻokahi wale nō extruded Aluminum Hoʻololi pinepine ka ʻāpana i nā ʻāpana kila he nui.

Consumer uilaʻoe: Pulu ka wela no nā ʻāpana a me nā mea hana e hoʻohana pinepine i nā extrusions 6061 a i ʻole 6063. Hoʻoneʻe pono ka conductivity thermal i ka wela ʻoiai e hana maikaʻi ana kēia mau mea hao no ka geometry fin pololei.

Hāʻawi Hana: Hilinaʻi nā mīkini kaumaha i ka 6082-T6 no nā mōlina kūkulu a me nā ʻāpana hāpai ukana kahi e pono ai ka ikaika maoli. Hana maikaʻi hoʻi ia i nā mīkini, no laila ʻaʻole lilo ka ʻeli ʻana a me ke kī ʻana no ka ʻākoakoa ʻana i mea ʻeha.

pāhana ikehuKe hoʻohana nui nei nā mōlina panela solar a me nā hale kau ʻana i ka 6061-T5. ʻO ka hui pū ʻana o ka ikaika, ke kūpaʻa i ka pala, a me ke kaumaha māmā e hana kūpono no nā ʻōnaehana kau ma luna o ka hale a me ka honua.

Hoʻopau a me ka Hana Lua

Hoʻopili pololei ʻia nā mea hoʻohuihui 6-series. Hana maikaʻi nā kaʻina hana GTAW a me GMAW maʻamau me 6061, ʻoiai pono ka 6082 i ka hoʻomohala ʻana i nā kaʻina hana akahele. ʻO ka anodizing ka hoʻopau maʻamau, me nā uhi pale hale anodizing Type II a me Type III he 5-25 micrometers ka mānoanoa a i ʻole ka mānoanoa. Hoʻopili maikaʻi ka uhi pauka i ka alumini i hoʻomākaukau ʻia, a i hui pū ʻia me ke kūpaʻa kūlohelohe o ka mea hoʻohuihui, hoʻopau ʻoe me nā hoʻopau e mau no nā makahiki he ʻumi i nā noi waho.

Lalo Line

Ua loaʻa i ka ʻohana alumini 6-series kona wahi ma ke ʻano he kūlana no ka hana extrusion no ka mea e hana pono ana ia i ka hana. Hoʻokō ka haku mele i kēlā wahi momona kahi e loaʻa ai iā ʻoe ka ikaika kūpono me ka ʻole o ka mōhai ʻana i ke ʻano āu e pono ai no nā ʻaoʻao paʻakikī. ʻO ke kūpaʻa i ka palaho ʻo ia hoʻi ʻaʻole pono ʻoe e uhi i nā mea āpau e pale aku ai i ka palaho ʻana. No ka mea, aia i loko o ka ʻohana kekahi mau papa, hiki iā ʻoe ke koho pololei i kāu mea e pono ai—ka ikaika kiʻekiʻe loa, nā ʻano paʻakikī, ka pono o ke kumukūʻai, a i ʻole nā ​​mea nui loa no kāu noi. Ke hoʻomau nei ka hoʻoikaika ʻana no nā mea māmā a lilo ka hoʻomau i mea nui, e noho mau nā extrusions alumini 6-series i mua a waena i ka hana ʻana ma ka honua holoʻokoʻa.
