7 series txhuas alloys yog aluminium magnesium zinc tooj liab hlau, feem ntau yog zinc, tab sis qee zaum qee qhov me me ntawm magnesium thiab tooj liab tau ntxiv. Superhard aluminium alloy muaj zinc, txhuas, magnesium thiab tooj liab tooj liab, uas yog ze rau qhov nyuaj ntawm cov hlau.
7 series aluminium alloys yog cov khoom siv kho cua sov, koom nrog superhard alloys alloys, nrog kev hnav zoo, ua kom nrawm nrawm dua li 6 series cov hlau phom thiab ua haujlwm tau zoo.
7 series aluminium alloy kuj tseem yog Aviation series, thiab nws daim ntawv thov: Aviation (lub dav hlau nqa cov khoom sib tw, tsaws iav), foob pob hluav taws, kiv cua thiab lub dav hlau.
Tus neeg sawv cev ntawm xya series txhuas phaj yog 7075, uas feem ntau muaj zinc.
7075 txhuas phajyog kev nyuaj siab txo thiab yuav tsis deform thiab warp tom qab ua tiav. 7075 txhuas phaj muaj cov thermal conductivity siab, uas tuaj yeem ua rau lub sijhawm luv thiab txhim kho kev ua haujlwm tau zoo.
7075 feem ntau yog ua los ntawm kev ua siab tawv. Nws yog aluminium alloy nrog siab tawv thiab siab zog. Nws yog feem ntau siv hauv kev tsim cov dav hlau dav hlau thiab cov txheej txheem kev nyuaj siab thiab cov pwm uas xav tau lub zog siab thiab muaj zog tiv taus xeb.
