ʻO ka alumini alumini 7075 (i ʻike ʻia he alumini mokulele a i ʻole alumini aerospace) ʻo ia ka alloy mua o ka ikaika kiʻekiʻe i haku ʻia e Al-Zn-Mg-Cu i hiki ke hoʻohui maikaʻi i nā pono o ka hoʻopili ʻana o ka chromium e hoʻomohala i ka pohā koʻikoʻi-corrosion. kū'ē i nā huahana pepa.

ʻO ka paʻakikī o ka alumini alumini 7075 t6 pāpaʻi he 150HB, ʻo ia ka alumini alumini paʻakikī kiʻekiʻe. ʻO 7075T6 ka pā alumini alumini he papa alumini mīkini pololei a ʻo kekahi o nā alumini alumini i kūʻai ʻia. ʻO ka mea hoʻohui nui o ka 7075 alumini alloy series he zinc, nona ka ikaika ikaika, nā waiwai mechanical maikaʻi, a me ka hopena anode.

Nā hemahema o 7075-T6 Aluminum

ʻO ka 7075 alumini alumini e hōʻike i kahi kūlana paʻa no nā mea waiwai nui me kahi hui kūpono loa o nā waiwai no ka hapa nui o nā hana. Eia nō naʻe, loaʻa iā lākou kekahi mau drawbacks i mea nui e noʻonoʻo ai:

Ke hoʻohālikelike ʻia me nā alumini alumini ʻē aʻe, ʻoi aku ka haʻahaʻa o ka 7075 i ka corrosion. Inā makemake ʻia ka hoʻoikaika ʻana i ke koʻikoʻi-corrosion cracking resistance, ʻoi aku ka maikaʻi o ka alumini 7075-T7351 ma mua o ka 7075-T6.

ʻOiai ka loaʻa ʻana o ka machinability maikaʻi, ʻoi aku ka haʻahaʻa o kona ductility ke hoʻohālikelike ʻia me nā alloys 7000-series ʻē aʻe.

He mea kiʻekiʻe kona kumukūʻai, e kaupalena ana i kona hoʻohana ʻana.
