Txheej txheem cej luam
7475 aluminium alloy yog ib qho hlau uas muaj zinc hnyav feem pua. Nws kuj muaj magnesium, silicon thiab chromium.
7475 alloy tsis tuaj yeem welded. Nws muaj ntau lub caij nplooj ntoos hlav rov qab vim nws lub zog. Nws muaj siab machinability.
7475 txhuas ntawv feem ntau muaj 40% nce hauv toughness thaum piv rau 7075 txhuas. Thaum cov yam ntxwv ntawm kev ua tau zoo ntawm 7075 zoo ib yam, 7475 txhuas ntawv muaj kev txhim kho kev qaug zog thiab kev tiv thaiv corrosion piv nrog thiab feem ntau zoo dua li lwm cov qib siab aluminium. 7475 aluminium ntawv yog tsim rau cov ntawv thov uas suav nrog kev siv tshuab ua kom muaj zog, txhim kho pob txha toughness, thiab qaug zog tawg tawm yog qhov tseem ceeb dua.
1. Cov txheej txheem cej luam tshwj xeeb tau lees paub tias tag nrho cov aviation aluminium alloy series tuaj yeem dhau cov txheej txheem tshuaj xyuas ultrasonic. Nws tsis muaj porosity, tawg, npuas thiab impurities.
Kev Paub meej thiab Specifications
Cov lus piav qhia thiab cov rooj khaws cia los ntawm cov ntaub ntawv khaws cia ntawm cov khoom siv txhuas.

7475 Aluminium Sheet Properties
1. Cov txheej txheem cej luam tshwj xeeb tau lees paub tias tag nrho cov aviation aluminium alloy series tuaj yeem dhau cov txheej txheem tshuaj xyuas ultrasonic. Nws tsis muaj porosity, tawg, npuas thiab impurities.
2. Internal stress: Cov txheej txheem pre-stretching zoo tag nrho tshem tawm cov kev ntxhov siab sab hauv, thiab nws tsis warp, tawg lossis deform thaum ua.
3. Kev ua siab ntev: Nws ua raws li American Society for Testing and Materials (ASTM) thiab Aerospace Material Specifications (AMS).
4. Kev ua tau zoo: Qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg, lub zog thiab hardness yog tsawg, yog li ntawd, nws muaj kev ua haujlwm zoo.
5. Uniformity: RuiYi Aluminium muaj kev kho cua sov tshuab. Thaum 7475 txhuas ntawv yog qis dua 300mm thickness, lub zog thiab hardness yuav khaws cia zoo ib yam.
6. Kev ruaj ntseg: Tag nrho cov txheej txheem ntau lawm yog tswj los ntawm lub computer, nrog rau ob peb tib neeg kev sib txawv, thiab cov kev ua tau zoo tib yam tuaj yeem lav rau ntau cov khoom sib txawv.
7. Cov nyhuv anodizing: Nws cov nyhuv anodizing yog ib yam thiab ci, thiab tsis muaj qhov tsis xws luag.
8. Corrosion kuj: Nws muaj kev ntxhov siab zoo corrosion kuj thiab yuav tsis ua rau dents lossis blacken nyob rau hauv lub sij hawm ntev siv nyob rau hauv ntau yam xov xwm (xws li dej vapor, qaug zog acid thiab qaug zog alkali, thiab lwm yam.)
9. Qhov kub thiab txias tsis kam: Nws yuav ua rau tsis muaj deformation mus tas li thaum ua haujlwm ntawm 400 ° C.
