Lub 7075 txhuas alloy phaj yog lub txias forging alloy nrog siab zog thiab deb zoo dua me ntsis steel. 7075 yog ib qho tseem ceeb tshaj kev lag luam. 7075 aluminium alloy yog compact hauv cov qauv thiab muaj zog hauv corrosion kuj. Nws yog qhov zoo tshaj rau cov aviation thiab nkoj phaj. Cov kev sib txhuam ntawm qhov kev sib zog, kev kho khoom zoo thiab cov tshuaj tiv thaiv anodic. Txhuav ua kom zoo ua rau kev nqhis dej kom zoo dua qub thiab cov cuab yeej siv kuj hnyav.
Zinc yog lub ntsiab hlau loj tshaj plaws hauv 7075. Ntxiv magnesium rau cov hlau txhuam uas muaj 3% -7.5% zinc tsim tau MgZn2 nrog qhov zoo tshaj plaws ntawm kev tswj fais fab, uas ua rau kev kho cua sov ntawm cov hlau txaij zoo dua li ntawm Al-Zn binary alloy. Nrog rau kev zinc thiab magnesium cov ntsiab lus nyob rau hauv cov alloy, lub zog tensile yuav ntxiv lawm, tab sis qhov kev nyuaj siab corrosion kuj thiab spalling corrosion kuj yuav txo. Txoj kev kho cua sov tuaj yeem ua tau zoo ntawm cov yam ntxwv muaj zog heev. 7075 cov ntaub ntawv feem ntau ntxiv nrog ib qho me me ntawm tooj liab, chromium thiab lwm yam kev sib tov. Ntawm lawv, 7075-T651 aluminium alloy yog cov feem ntau superior. Nws yog hu ua qhov khoom zoo tshaj plaws ntawm txhuas alloy, nrog siab zog thiab deb superior rau tej yam me me hlau. Cov hlau muaj kev sib raug zoo thiab cov tshuaj tiv thaiv anodic. Cov neeg sawv cev xws li aerospace, kev tuag, kev ua lag luam thiab khoom siv, cuab tam thiab kev sib kho, tshwj xeeb tshaj yog rau cov khoom siv dav hlau thiab lwm yam kev siab-kev siab nrog cov muaj zog thiab corrosion kuj.
