7075-T6 Aluminium Txheej txheem cej luam
7075-T6 txhuas yog ib qho ntawm feem ntau siv tempers ntawm 7075 alloy, tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov yuav tsum tau.muaj zog heev. Nws cov cua sov- kev kho mob suav nrogtshuaj kho cua sov ua raws li kev laus kev laus, tso cai rau cov hlau mus txog nws cov khoom siv kho kom zoo.
Kev kho cua sov:Cov hlau yog rhuab mus rau qhov kub siab kom ntseeg tau tias kev faib tawm ntawm cov hlau alloying xws li zinc.
Artificial Aging:Tom qab txias, cov khoom yog reheated ntawm qhov kub thiab txias los txhawb cov nag lossis daus hardening, nce lub zog thiab hardness.
