Chemical Properties ntawm2024 Aluminium

Txhua lub alloy muaj qhov feem pua ​​​​ntawm cov alloying ntsiab lus uas imbue lub hauv paus aluminium nrog qee qhov txiaj ntsig zoo. Hauv 2024 aluminium alloy, cov feem pua ​​​​ntawm cov ntsiab lus hauv qab no cov ntaub ntawv. Tias yog vim li cas 2024 txhuas paub txog nws lub zog siab vim tooj liab, magnesium, thiab manganese ua kom muaj zog ntawm txhuas alloys.

Chemical Composition WT (%)
Silicon	Hlau	Tooj	Magnesium	Manganese	Chromium	Zinc	Titanium	Lwm tus	Aluminium
0.5	0.5	3.8-4.9	1.2 ~ 1.8 hli	0.3 ~ 0.9 hli	0.1	0.25	0.15	0.15	Tseem tshuav

Corrosion Resistance & Cladding

Bare 2024 aluminium alloy yog qhov cuam tshuam rau corrosion ntau dua li lwm cov txhuas alloys, yog li cov tuam ntxhab tau hais txog qhov teeb meem no los ntawm txheej txheej ntawm cov hlau tsis muaj zog nrog cov txheej txheem corrosion-resistant hlau.

Thaum tshav kub kub-kev kho mob kom muaj zog ntxiv

Hom 2024 aluminium tau txais nws qhov zoo tshaj plaws lub zog zoo tsis yog los ntawm kev sib xyaw ib leeg xwb, tab sis los ntawm cov txheej txheem los ntawm qhov uas yog nws kho cua sov. Muaj ntau ntau cov txheej txheem sib txawv, lossis "tempers" ntawm txhuas (muab tus tsim -Tx, qhov twg x yog ib tug-rau-tsib tus lej ntev), uas txhua tus muaj lawv cov khoom tshwj xeeb txawm tias yog tib lub alloy.

Mechanical Properties

Rau cov hlau xws li 2024 txhuas, qee qhov kev ntsuas tseem ceeb yog qhov kawg ntawm lub zog, lub zog tawm los, lub zog shear, qaug zog, nrog rau cov qauv ntawm elasticity thiab shear modulus. Cov txiaj ntsig no yuav muab lub tswv yim hais txog kev ua haujlwm, lub zog, thiab kev siv tau ntawm cov khoom siv, thiab suav nrog hauv qab cov ntaub ntawv.

Mechanical Properties	Metric	Lus Askiv
Qhov kawg Tensile Strength	469 MPa ua	68 000 psi
Tensile Yield zog	324 MPa rau	47 000 psi
Shear Strength	283 MPa ua	41 000 psi
Kev qaug zog	138 MPa rau	20000 psi
Modulus ntawm Elasticity	73.1 gvp	10 600 ksg
Shear Modulus	28 GPA	4060 ua

Kev siv ntawm 2024 Aluminium

Hom 2024 txhuas muaj kev ua haujlwm zoo heev, kev ua haujlwm zoo, lub zog siab, thiab tuaj yeem ua los tiv thaiv corrosion nrog cladding, ua rau nws xaiv qhov zoo tshaj plaws rau kev siv dav hlau thiab tsheb. 2024 txhuas yog siv thoob plaws hauv ntau lub lag luam, tab sis qee qhov kev siv rau qhov zoo tshaj plaws alloy yog raws li hauv qab no:
