7075 Aluminium yog dab tsi?
7075 aluminium alloy yog qhov siab -lub zog aerospace- qib aluminium feem ntau siv rau hauv cov ntawv thov uas qhov siab tshaj plaws txhua yam muaj zog yog qhov tseem ceeb thiab tsis tshua muaj corrosion kuj tsis yog qhov yuav tsum tau ua.
Aluminium alloys feem ntau paub txog lawv qhov muaj zog tiv thaiv corrosion, thiab lawv cov cuab yeej siv zog nce ntawm subzero kub, ua rau lawv haum rau qis - daim ntawv thov kub. Txawm li cas los xij, lawv lub zog yuav txo qis thaum raug kub heev. Ntawm lawv, 7075 txhuas nyob rau hauv T6 forging mob muaj lub zog tshwj xeeb thiab tau lees paub tias yog ib qho ntawm cov muaj zog tshaj plaws siv txhuas alloys. Qhov tseeb, Aluminium Alloy 7075 muab lub zog siab tshaj plaws ntawm cov qauv ntsia hlau tshuab alloys.
Lub T73 thiab T7351 tempers ntawm 7075 txhuas xa zoo heev tiv thaiv kev nyuaj siab corrosion cracking, uas ua rau no alloy ib tug txhim khu kev qha lwm txoj rau 2024, 2014, thiab 2017 txhuas alloys nyob rau hauv ntau yam ntaub ntawv tseem ceeb. T6 thiab T651 tempers muaj kev ncaj ncees machinability. Vim nws cov yam ntxwv muaj zog zoo, alloy 7075 yog dav siv hauv kev lag luam aerospace thiab kev tiv thaiv.
Cov npe nrov thiab cov npe lag luam rau cov hlau no suav nrogUNS A97075, ISO AlZn5.5MgCu, AA7075-T6, Al7075-T6, AA7075-T73, thiab Al7075-T73.
Khoom yam ntxwv
7075 aluminium yog alloyed feem ntau nrog zinc thiab xa cov qib zog piv rau cov hlau thaum tuav qhov qis qis dua. Nws muaj kev qaug zog zoo thiab ua haujlwm nruab nrab, txawm hais tias nws qhov kev tiv thaiv corrosion yog qis dua li ntawm ntau lwm cov aluminium alloys.
Thanks to its combination of high strength, low density, favorable thermal properties, and excellent polishability, 7075 aluminum is extensively used in mold and tooling manufacturing. Cov khoom raug muab rau cov hlau no sawv cev rau cov txiaj ntsig nruab nrab raws li qhov ntau thiab tsawg thiab kev tsim khoom thiab yog npaj rau kev sib piv ntawm alloys thiab tempers nkaus xwb. Cov txiaj ntsig no tsis tau lees paub thiab yuav tsum tsis txhob siv los ua cov ntaub ntawv tsim.
