7075-T651 Aluminium Phaj Properties
7075-T651 txhuas phajyog yus muaj los ntawm siab hardness thiab superior mechanical zog. Cov khoom siv lub cev thiab cov cuab yeej cuab tam muaj xws li:
Hardness: kwv yees150 HB
Ceev: txog2.81 g / cm³
Tensile zog: nyob ib ncig ntawm524 MPa ua
Elongation: kwv yees11%
Tom qab kev kho cua sov kho, cov hlau muaj cov yas zoo heev, muaj zog cua sov- kev kho mob, lub zog siab ntawm qhov kub txog li 150℃, thiab zoo qis - kub ua haujlwm. Txawm li cas los xij, nws qhov kev ua haujlwm vuam yog qhov tsis zoo, thiab nws qhia tau hais tias muaj kev nyiam rau kev ntxhov siab corrosion tawg. Vim li no, kev tiv thaiv nto xws li txhuas cladding lossis lwm yam kev tiv thaiv kev kho mob feem ntau siv rau kev siv tswv yim.
Lub ntsiab alloying ntsiab nyob rau hauv7075 aluminium phajyog zinc, nrog magnesium thiab tooj liab ntxiv rau ntxiv dag zog. Ua kom cov zinc thiab magnesium cov ntsiab lus tuaj yeem txhawb nqa lub zog tensile, tab sis nws kuj tseem tuaj yeem txo cov kev ntxhov siab corrosion thiab exfoliation corrosion, yuav tsum tau ceev faj sib npaug thiab kev tswj xyuas.
