7075-T6 Aluminium yog dab tsi?
7075 aluminium alloy, nrog zinc raws li nws cov ntsiab lus alloying, yog dav hu uaaircraft aluminiumlos yogaerospace aluminium. Nws yog thawj lub siab -lub zog Al-Zn-Mg-Cu alloy kom ua tiav cov chromium, txhim kho kev tiv thaiv kev ntxhov siab-corrosion tawg hauv cov khoom siv.
Cov tshuaj muaj pes tsawg leeg ntawm 7075 txhuas muaj kwv yees li87.1-91.4% txhuasthiab5-6% zinc, nrog2.1-2.9% magnesiumthiab1.2-2% tooj liab. Cov khoom me xws li silicon, titanium, chromium, hlau, manganese, thiab lwm yam yog txhua yam txwv tsis pub ntau tshaj.0.5%.
7075-T6 txhuas yog hais txog 7075 alloy nyob rau hauvT6 zog. Qhov mob no yog ua tiav los ntawm kev kho cua sov, homogenization ntawm cov cam khwb cia hlau nyob ib puag ncig450 degreerau ob peb teev, ceev quenching, thiab ntxiv dag zog aging ntawm120℃rau kwv yees li 24 teev. Nyob rau theem no, cov alloy ncav cuag nws cov cuab yeej cuab tam tus qauv thiab ua tiavncov zog.
Dab tsi ua rau 7075 Txhuas Sawv Los Ntawm Txhuas Alloys?
Lub alloying system ntawm 7075 series tshwm simlub zog siab tshaj plaws ntawm cov khoom lag luam muaj aluminium alloys, ua rau nws cov neeg kho tshuab kev ua tau zoo piv rau cov hlau ntau. Txawm hais tias nws lub zog tshwj xeeb yog ib qho ntawm nws qhov zoo tshaj plaws, nws yog kev sib xyaw ua ke ntawm cov khoom -Tsawg ceev, zoo heev machinability, thiab zoo corrosion kuj- uas ua rau 7075 txhuas tshwj xeeb yog tsim rau cov khoom siv hluav taws xob hnyav heev.
Nws yuav tsum tau muab sau tseg tias, piv nrog rau lwm yam txhuas alloys, lub corrosion kuj ntawm 7075 yog kuj txwv. Txawm li cas los xij, nws tseem ua tau zoo dua li ntau cov alloys hauv2000 series.
Hauv ntau daim ntawv thov, 7075 txhuas yog suav nrog nrog 2024 txhuas. Thaum xav tau kev ua haujlwm siab dua mechanical,7075 tseem yog qhov nyiam xaiv.
