ʻO 7075 a me 7050 nā alumini alumini ikaika kiʻekiʻe i hoʻohana mau ʻia i ka aerospace a me nā noi koi ʻē aʻe. ʻOiai kaʻana like lākou i kekahi mau mea like, loaʻa iā lākou nā ʻokoʻa koʻikoʻi:

Huina

7075 alumini aluminiloaʻa ka alumini, zinc, keleawe, magnesium, a me nā ʻāpana o ka chromium. Ua kapa ʻia ʻo ia i kekahi manawa he mea hoʻohui mokulele.

Ka Hui Kimia WT(%)
Silika	hao	keleawe	Magnesium	Manganese	Chromium	Zinc	Titanium	ʻO nā mea ʻē aʻe	Aluminum
0.4	0.5	1.2~2	2.1~2.9	0.3	0.18~0.28	5.1~5.6	0.2	0.05	Koena

7050 alumini aluminiloaʻa pū kekahi i ka aluminika, zinc, copper, a me ka magnesium, akā ʻoi aku ka nui o ka zinc ma mua o 7075.

Ka ikaika

ʻIke ʻia ʻo 7075 no kona ikaika ʻokoʻa, e hana ana ia i kekahi o nā alumini alumini ikaika loa i loaʻa. Loaʻa iā ia ka ikaika tensile hope loa a me ka ikaika e hoʻohālikelike ʻia me 7050.

Hāʻawi ʻo 7050 i ka ikaika maikaʻi loa, akā ʻoi aku ka haʻahaʻa haʻahaʻa o nā waiwai ikaika i hoʻohālikelike ʻia me 7075.

Pale ʻino

ʻOi aku ka maikaʻi o ke kūpaʻa ʻana o nā ʻāpana ʻelua, akā ʻoi aku ka maikaʻi o ke kūʻē ʻana o 7050 i ke koʻikoʻi o ka pohā ʻino i hoʻohālikelike ʻia me 7075 ma muli o kona kiʻekiʻe o ka zinc.

Paleʻa luhi

Hōʻike maʻamau ʻo 7050 i ke kūpaʻa luhi ʻoi aku ka maikaʻi ma mua o 7075, no laila kūpono ia no nā noi kahi e hopohopo ai ka hoʻouka ʻana a i ʻole ke koʻikoʻi.

Weldability

ʻOi aku ka maikaʻi o ka weldability i ka 7050 i hoʻohālikelike ʻia me 7075. ʻOiai hiki ke hoʻopaʻa ʻia nā ʻāpana ʻelua, ʻoi aku ka liʻiliʻi o 7050 i ka haki ʻana i nā kaʻina hana kuʻi.

Nā noi

Hoʻohana maʻamau ʻia ʻo 7075 i nā hale mokulele, nā paikikala kiʻekiʻe, nā pū ahi, a me nā noi ʻē aʻe kahi koʻikoʻi ka nui o ka ikaika-a-kaumaha a me ka paʻakikī.

Hoʻohana pū ʻia ʻo 7050 i nā noi aerospace, ʻoi aku ka nui o nā wahi e koi ʻia ai ka ikaika kiʻekiʻe, ke kūpaʻa luhi maikaʻi, a me ke kūpaʻa corrosion, e like me nā papa fuselage mokulele a me nā bulkheads.

Mīkini

Hiki ke hana ʻia nā ʻāpana ʻelua, akā ma muli o ko lākou ikaika kiʻekiʻe, hiki iā lākou ke hōʻike i nā pilikia i ka mīkini. Eia naʻe, ʻoi aku ka maʻalahi o 7050 i ka mīkini e hoʻohālikelike ʻia me 7075.
