Aoyin 7075 aluminiyamu mbale imatanthawuza za aloyi omwe amagwiritsidwa ntchito kwambiri mu 7-series aluminium alloy. Amagwiritsidwa ntchito kwambiri m'magawo odulira a CNC, oyenera mafelemu a ndege ndi zida zamphamvu kwambiri. Aluminiyamu ya 7-series ali ndi Zn ndi Mg. Zinc ndiye chinthu chachikulu cholumikizira mndandandawu, kotero kukana kwa dzimbiri ndikwabwino kwambiri, ndipo kagawo kakang'ono ka magnesium aloyi kumatha kupangitsa kuti zinthuzo zifike kumphamvu kwambiri pambuyo pochiritsa kutentha.

Aluminiyamu ya 7-series ndi Al-Zn-Mg-Cu super-hard aluminium. Aloyiyi idagwiritsidwa ntchito popanga ndege chakumapeto kwa zaka za m'ma 1940 ndipo ikugwiritsidwabe ntchito kwambiri pamakampani opanga ndege. Amadziwika ndi mapulasitiki abwino pambuyo pa chithandizo chamankhwala, makamaka kulimbikitsa kutentha kwamphamvu, mphamvu yayikulu pansi pa 150 ° C, komanso mphamvu yabwino kwambiri yotsika; weldability osauka; kupsinjika dzimbiri akulimbana chizolowezi; ayenera yokutidwa ndi aluminiyamu kapena njira zina Chitetezo ntchito. Kukalamba kwa magawo awiri kumapangitsa kuti alloy athe kukana kupsinjika kwa dzimbiri. Pulasitiki mumkhalidwe wotsekedwa ndi kuzimitsidwa ndi wotsika pang'ono kuposa momwe 2A12 ikuyendera. Ndibwinoko pang'ono kuposa 7A04, 7075 aluminium mbale static kutopa. Notch sensitive, kupsinjika kwa dzimbiri ndikwabwino kuposa 7A04. Kachulukidwe ndi 2.85g/cm3.

Ubwino wa 7075 aluminiyamu mbale

1. Aloyi yochizira kutentha kwambiri yamphamvu kwambiri.

2. Good makina katundu.

3. Kugwiritsa ntchito bwino.

4. Zosavuta kukonza komanso kukana bwino kuvala.

5.T7351 boma kumawonjezera dzimbiri mng'alu kukana

6. Zida zamphamvu kwambiri zopangira zigawo zamapangidwe apamwamba.

7075 aluminium mbale nthawi zambiri imawonjezedwa ndi mkuwa pang'ono, chromium, ndi ma aloyi ena. Aloyi ya A7075-aluminium ndi yapamwamba kwambiri.

Imadziwika kuti ndi yabwino kwambiri mu aloyi ya aluminiyamu, ndi yamphamvu kwambiri komanso yopambana kuposa chitsulo chilichonse chofatsa. Aloyi iyi imakhala ndi machitidwe abwino amakina komanso anodic.
