Dab tsi ntawm cov hlau muaj nyob hauv kev ua haujlwm ntawm cov khoom siv dav hlau

2021/07/29


7015 txhuas hlau, Asmeskas deformed aluminium thiab aluminium alloys. Aluminium alloys tau muab faib ua ob pawg: cam khwb cia txhuas alloys, uas tau siv hauv lub xeev pov tseg; deformed aluminium alloys, uas tuaj yeem tiv taussiab uathiab muaj cov khoom siv dag zog siab dua li lub xeev pov tseg. Nws tuaj yeem ua tiav rau ntau yam ntaub ntawv thiab kev qhia tshwj xeeb ntawm cov khoom siv txhuas txhuas. Nws feem ntau yog siv hauv kev tsim cov khoom siv dav hlau, khoom siv txhua hnub, lub qhov rooj thiab lub qhov rais rau kev tsim kho, thiab lwm yam. Â - Kev sib piv tus qauv: Alcoa (AA) 7015 â - Cov tshuaj lom neeg muaj pes tsawg leeg: Al Al (min.): Residual Si: ‰. .0.20 Fe Fe: â ‰ .300.30 Cu Cu: 0.06--0.15 Mn Mn: â ‰ .100.10 Mg Mg: 1.3--2.1 Cr Cr-2.1 Chromium Cr: .1 .1 .10.15 Zinc Zn: 4.6--5.2 Zirconium Zr: 0.10-0.20 Titanium Ti: ‰ ‰0.10 Lwm yam ntsiab lus tsis tau teev tseg: txhua: â ‰ .00.05; tag nrho: 15 15 15 0.156061 txhuas hlau yog qhov ua tau zoo aluminium alloy tsim los ntawm kev kho cua sov ua ntej ncab txheej txheem, nws lub zog tsis tuaj yeem piv nrog 2XXX series lossis 7XXX series, tab sis nws cov yam ntxwv magnesium thiab silicon alloy, muaj zoo heevua performance, excellent welding characteristics and plating, good corrosion resistance, high toughness and no deformation afterua, dense material without defects and easy to polish, easy to color film, excellent oxidation effect, and other excellent characteristics. The main alloying elements of 6061 aluminum alloy are magnesium and silicon, and form Mg2Si phase. If it contains a certain amount of manganese and chromium, it can neutralize the bad effect of iron; sometimes a small amount of copper or zinc is added to improve the strength of the alloy without making its corrosion resistance significantly reduced; there is a small amount of copper in the conductive material to offset the bad effect of titanium and iron on the conductivity; zirconium or titanium can refine the grain and control the recrystallization organization; in order to improve the machinability, ntxiv txhuas thiab bismuth ntxiv tau. Cov ntsiab lus tseem ceeb hauv 6061 txhuas hlau yog magnesium thiab silicon, uas muaj lub zog nruab nrab, tiv thaiv xeb zoo, weldability thiab oxidation zoo. Nws cov tshuaj lom neeg tseem ceeb yog (pawg feem ntawm txhua ntu): Copper Cu: 0.15-0.4 Manganese Mn: 0.15 Magnesium Mg: 0.8-1.2 Zinc Zn: 0.25 Chromium Cr: 0.04 --- 0.35 Titanium Ti: 0.15 Silicon Si: 0.4--0.8 Hlau Fe: 0.7 Aluminium Al: seem
