7075 txhuas daim hlau sawv cev rau lub ntsiab lus ntawm high- Lub zog aluminium alloys thiab - qib kawm. Tsim muaj ntawm cov zinc, magnesium, thiab tooj liab, cov txheej txheem tshaj plaws zoo li 6061 los ntawm ze li 80% 6. Cov phiaj 'tshwj xeeb microstructure, ua kom zoo dua los ntawm T6 lossis T651 Tempering, uas muaj zog {14} {14} {14} {14} {14} {{14} {{14} - Qhov hnyav tshaj plaws xws li tis panels thiab fuselage thav ntawv. Lawv txias - ua haujlwm variants txuas ntxiv hardness ntxiv thaum tswj txoj kev ruaj khov rau cov tshuab sab hauv. Tsis zoo li alloys, 7075 daim phiaj pom kev nkees nkees ua rau muaj kev thauj khoom zoo tshaj plaws, tus yam ntxwv tseem ceeb heev rau kev ua lub dav hlau ntev. Cov khoom siv muaj peev xwm khaws tau lub zog ntawm kev nce qib kub (nce mus txog 150}}}}} kev kub ntxhov rau kev ua haujlwm ntawm heltceptibility thiab nce tau kev lom zem rau kev ntxhov siab corrosion. Cov khoom no yog meticulously sib npaug los ntawm kev tswj hwm alloyos piv, muab 7075 raws li cov khoom siv uas tsis muaj zog yog qhov tsis muaj zog.
Cov neeg kho tshuab prowess ntawm 7075 txhuas daim hlau yog lawv cov hluav taws xob ua kom zoo nkauj (229. Lawv lub zog nkees muaj zog, tshwj xeeb tshaj yog cov neeg sib cav sib luag, ua kom zoo tshaj plaws rau cov cuab yeej tseem ceeb rau cov dav hlau zoo li cov iav thiab tis spars. Cov phiaj 'hardness (feem ntau 150 {{{}} 160 hbw) thiab tsis kam rau qhov chaw xav tau hauv T6 Tauj yuav tsum tau ceev faj tuav thaum sib tsoo. Cov kev kho saum npoo xws li qhov anodizing tuaj yeem txo cov kev sib xyaw ua ke, txawm tias zinc-nplua nuj ntau yuav ua rau oxidation inconsistencies. Cov khoom no, ua ke nrog Alloy lub peev xwm los tswj cov seem stabensional tsoos-machining, underscore nws nyob rau hauv aerospace thiab precision caporingort.
