Lub zog siab: Lub zog ntawm 7 series aluminium alloy zoo dua li cov hlau me me. Nws lub ntsiab alloying ntsiab yog zinc thiab magnesium. Cov qauv MgZn2 tsim los ntawm zinc thiab magnesium muaj qhov ua kom muaj zog ntxiv, ua rau cov kev kho cua sov ntawm 7 series txhuas daim hlau zoo dua li lwm cov phaj txhuas. . Raws li zinc thiab magnesium cov ntsiab lus nce, lub zog ntawm aluminium phaj yuav nce ntxiv. Tshwj xeeb tshaj yog thaum kub qis dua 150 degree, kev ua haujlwm zoo dua.
High mechanical zog: 7 series aluminium alloys muaj cov khoom siv zoo heev, suav nrog lub zog siab, hardness thiab zoo plasticity. Vim tias qhov me me thiab txawm tias qhov sib faib ntawm cov khoom siv lead ua sab hauv, 7 series txhuas phaj muaj qhov hnav tsis kam, thiab nws cov qib siab ntawm drilling kev ua tau zoo kuj tsis tshua muaj. Cov khoom no ua rau nws tsim nyog rau kev tsim cov khoom siv dav hlau uas yuav tsum tau tiv taus cov khoom hnyav thiab kev kub ceev.
