Daim ntawv thov ntawm 7075 Aluminium Alloy
7075 aluminium yog siv dav hauv kev lag luam aerospace vim nws lub zog tshwj xeeb tshaj plaws - rau - qhov hnyav piv. Nws yog siv nyob rau hauv ob qho tib si aircraft structural Cheebtsam thiab aircraft tawv, tab sis nyob rau hauv tej rooj plaub nws yog maj mam hloov los ntawm tej yam 6000-series alloys.
Tshaj li aerospace, 7075 txhuas feem ntau yog siv rau hauv kev tsim cov khoom siv pob zeb nce toj, cov tsheb kauj vab, thiab ntau yam siab -kev ua kis las. Nws tseem yog cov khoom siv tseem ceeb hauv kev siv tub rog, suav nrog cov khoom ntawm US M16 phom. Tsis tas li ntawd, vim nws lub zog zoo heev - rau- qhov hnyav thiab qhov zoo corrosion kuj, 7075 txhuas yog siv los ua cov khoom siv hauv cov khoom siv hauv cov khoom siv ceramic rau cov tub rog tsheb.
NtawmGNEE, 7075 txhuas cov khoom tau muab los ua kom tau raws li cov kev xav tau ntawm kev lag luam thiab kev tiv thaiv.
Cov yam ntxwv muaj zog ntawm 7075 Aluminium
Wrought 7075 aluminium alloys tuaj yeem ua tiav qhov kawg tensile lub zog siab tshaj 572 MPa thaum tuav qhov ntom ntom ntawm kwv yees li 2.8 g / cm³. Los ntawm kev sib piv, 304 stainless hlau muaj lub zog tensile ntawm ib ncig ntawm 621 MPa tab sis qhov ceev ntau dua li ntawm 8 g / cm³.
Qhov no txhais tau hais tias 7075 txhuas xa tawm ze li ntawm 90% ntawm lub zog tensile ntawm 304 stainless hlau ntawm kwv yees li ib -feem peb ntawm qhov hnyav. Raws li qhov tshwm sim, rau cov khoom sib npaug ntawm qhov sib npaug, 7075 txhuas tuaj yeem muab yuav luag peb npaug ntawm qhov sib npaug ntawm qhov sib npaug ua los ntawm 304 stainless hlau.
Yuav ua li cas txheeb xyuas cov qib Aluminium Alloy
Txoj kev txhim khu kev qha tshaj plaws los txiav txim siab qib aluminium alloy yog los ntawm kev tshuaj xyuas cov lej tsim tau teev tseg hauv kev tsim khoom lossis cov khoom siv tshwj xeeb. Kev pom qhov txawv ntawm aluminium alloys yog qhov nyuaj heev, vim tias cov ntsiab lus alloying tsis hloov pauv zoo li.
Qee qhov xwm txheej, cov cim qhia dav dav xws li tus txheeb ze softness los yog dabtsi yog khoov tus cwj pwm -feem ntau pom los ntawm kev puas tsuaj rau tus qauv- tej zaum yuav muaj cov lus qhia tsawg. Cov khoom khaws cia tsis zoo uas qhia txog kev xeb kuj tseem tuaj yeem muab cov lus qhia tsis zoo rau kev faib tawm, tab sis cov txheej txheem no tsis meej.
Yam Tseem Ceeb Thaum Xaiv Aluminum Qib
Thaum xaiv qhov zoo tshaj plaws aluminium alloy, ntau yam tseem ceeb yuav tsum tau soj ntsuam:
Yuav tsum muaj zog: Txheeb xyuas seb koj tus qauv tsim puas tuaj yeem ua raws li cov khoom ntim uas xav tau kom ua tiav lub zog xav tau.
Fatigue Resistance: Qee cov aluminium alloys ua tau zoo dua hauv kev thauj khoom cyclic; nkag siab txog koj cov kev xav qaug zog yog qhov tseem ceeb.
Muaj peev xwm ua tau: Tsis yog tag nrho cov qib aluminium yog sib xws nrog txhua txoj kev tsim khoom, xws li forging lossis extrusion.
Fabrication thiab Assembly: Qee cov aluminium alloys nyuaj rau welded, thaum lwm tus zoo haum rau cov qauv welded.
Corrosion Resistance: Qee cov qhab nia ua tau tsis zoo nyob rau hauv ib puag ncig corrosive los yog ntub dej, hos lwm tus yog haum rau ntev - raug.
Kev puas tsuaj Tolerance: Alloys nrog elongation siab dua thaum so yog qhov tseem ceeb rau kev nyab xeeb -sensitive thiab lub neej- cov qauv tseem ceeb.
Nto Zoo: Yog tias qhov muag pom qhov teeb meem, xav txog qhov ua tiav ntawm qhov ua tiav thiab kev ua kom zoo nkauj ntawm txhua lub alloy.
GNEE txhawb nqa cov neeg siv khoom hauv kev xaiv cov aluminium alloy uas tsim nyog tshaj plaws raws li cov txheej txheem thiab daim ntawv thov no - cov cai tshwj xeeb.
