ʻO ka pahu alumini 7075 he mea hoʻoheheʻe ʻia i mālama ʻia i ke anu me ka ikaika kiʻekiʻe, ʻoi aku ka maikaʻi ma mua o ke kila māmā.ʻO 7075 kekahi o nā alloys ikaika loa i kūʻai ʻia.ʻO ke kūpaʻa corrosion maʻamau, nā waiwai mechanical maikaʻi a me ka hopena anodic.Hāʻawi nā hua ʻai ʻoi aku ka maikaʻi o ka hoʻoheheʻe ʻana i ka hohonu, hoʻonui i ka pale ʻana i ka ʻaʻahu a me ka ʻōwili ʻana i nā kaula ʻokoʻa.Ua kapa ʻia ʻo 7075 alumini alumini ultra-high-strength alumini alloy.ʻO ka ikaika o ka hoʻouluʻana o ka'āpana e pili kokoke ana i ka ikaika tensile, ua kiʻekiʻe ke kiʻekiʻe o ka hopena, a he kiʻekiʻe hoʻi ka ikaika kiko'ī, akā, he haʻahaʻa ka plasticity a me ka ikaika wela.He mea maʻalahi ke kaʻina hana, loaʻa ka pale corrosion maikaʻi a me ka paʻakikī kiʻekiʻe.Hoʻohana nui ʻia kēia alloy i ka mokulele a me ka aerospace a ua lilo ia i hoʻokahi o nā mea hoʻolālā koʻikoʻi ma kēia kahua.ʻO 7075 nā huahana alumini bar i nā hiʻohiʻona o ka hoʻohuihui wela wela kiʻekiʻe, nā waiwai mechanical maikaʻi, ka hana, ka maʻalahi o ka hana ʻana, ke kūpaʻa ʻana, ka pale ʻana i ka corrosion, ke kūpaʻa oxidation a pēlā aku.
ʻO ka hui kemika a me nā waiwai mechanical o 7075 koʻokoʻo aluminika
