ʻIke paha ʻoe i nā ʻokoʻa ma waena o 6061 alumini alumini a me 7075 alumini alumini, a he aha nā māla i kūpono iā lākou?

Hoʻohui Kimia

6061 Aluminum Alloy: ʻO ka mea nuiʻO nā mea hoʻohuihui he magnesium(Mg) a me ke silika (Si), me ka nui o ke keleawe (Cu), manganese (Mn), etc.

7075 Aluminum Alloy: ʻO ka mea hoʻohui mua he zinc (Zn), me ka magnesium (Mg) a me ke keleawe (Cu) no ka hoʻoikaika ʻana.

Na Waiwai Mechanical

6061 Aluminum Alloy: Ka ikaika haʻahaʻa, me ka ikaika tensile o 200-300 MPa maʻamau ma hope o ka mālama ʻana i ka wela. Hāʻawi ia i ka ductility maikaʻi a me ke kūpaʻa luhi, hiki ke kū i kekahi deformation me ka ʻole o ka haki.

7075 Aluminum Alloy: ʻOi aku ka ikaika ma mua o 6061, me ka ikaika tensile ma mua o 560 MPa ma hope o ka mālama ʻana i ka wela. ʻOi aku ka paʻakikī a ʻoi aku ka maikaʻi i ke kūʻē ʻana i ke koʻikoʻi kiʻekiʻe a me nā ukana kaumaha.

Pale ʻino

6061 Aluminum Alloy: ʻOi loa ka pale ʻana i ka corrosion. ʻO ka hui pū ʻana o Mg a me Si e hana i kahi kiʻiʻoniʻoni oxide ma luna o ka ʻili, me ka pale ʻana i ka corrosion lewa a me kekahi corrosion kemika.

7075 Aluminum Alloy: ʻAʻole maikaʻi ka pale ʻana i ka corrosion ma muli o ke alo o ke keleawe. I loko o nā wahi ʻino e like me nā kūlana kai, hiki iā ia ke ʻino a koi pinepine i nā hoʻomaʻamaʻa kūikawā kūikawā (e laʻa, anodizing, pena).

ʻano lawelawe

6061 Aluminum Alloy: Maʻalahi e hana a hana. Hiki ke hana ʻia i loko o nā ʻano like ʻole ma o ka rolling, extrusion, forging, etc., a loaʻa iā ia ka weldability maikaʻi, kūpono no ka hana nui a me nā mea hana paʻakikī.

7075 Aluminum Alloy: ʻoi aku ka paʻakikī i ka mīkini,e koi ana i ka hana kiʻekiʻeʻenehana a me nā mea hana. ʻOiai e hoʻokō mau ana kona machinability i ka hapa nui o nā pono ʻoihana, ʻoi aku ka kiʻekiʻe o ke kumukūʻai.

Nā kahua noi

Hoʻohana nui ʻia ka alumini alumini 6061 i ka ʻoihana hana ma muli o kāna hana piha maikaʻi, e like me nā puka puka a me nā puka makani, nā pā pā; no ka hana ʻana i nā lako, nā mea pono o kēlā me kēia lā.

Hoʻohana nui ʻia ka alumini alumini 7075 i nā manawa i kiʻekiʻe loa nā koi ikaika, No ka aerospace, hoʻohana ʻia e hana i nā kaola mokulele, nā mea hoʻokele, nā ʻēheu a me nā mea nui ʻē aʻe; Ma ke kahua kaua, nā ʻāpana a me nā ʻāpana i hoʻohana ʻia i ka hana ʻana i nā mea kaua a me nā mea hana;

I ka hōʻuluʻulu manaʻo,6061 a me 7075 alumini aluminiʻokoʻa i ka haku mele ʻana, nā waiwai mechanical, ka pale ʻana i ka corrosion, a me ka machinability, e hoʻohana ana kēlā me kēia i ko lākou ikaika ma nā ʻano ʻokoʻa. Pono e hoʻokumu ʻia ke koho maʻamau i nā koi hoʻohana kūikawā a me nā kūlana kaiapuni.
