Nco tseg: Cov txiaj ntsig zoo ib yam tuaj yeem sib txawv nyob ntawm cov txheej txheem tsim khoom thiab muaj pes tsawg leeg hauv cov kev txwv tshwj xeeb.
Tensile Strength (Qhov kawg & Yield):
5052 txhuas muab lub zog nruab nrab tag nrho. O temper yog mos thiab ductile heev, thaum txias - ua haujlwm tempers (H3x series) muaj zog ntau dua. Ntawm lawv, H32 muaj qhov sib npaug zoo ntawm lub zog thiab kev tsim kho.
Elongation:
Ib qho kev ntsuas ntawm ductility. Lub annealed 5052-O temper txhawb kev sib sib zog nqus nqus thiab txoj kev tsim, thaum ductility maj mam txo nyob rau hauv siab hardening tempers.
Hardness:
Ntxiv nrog rau qib ntawm kev ua haujlwm txias, txhim kho hnav tsis kam.
Fatigue Strength:
5052 qhia txog kev ua haujlwm qaug zog, tshwj xeeb tshaj yog nyob rau hauv H3x tempers, ua rau nws tsim nyog rau cov khoom raug rov qab kev ntxhov siab. Txij li thaum aluminium alloys tsis muaj qhov tseeb endurance txwv, qaug zog yuav tsum tau xav txog thaum tsim.
Shear Strength:
Feem ntau nyob ib ncig ntawm 55% -60% ntawm qhov kawg tensile lub zog.
Lub cev muaj zog ntawm 5052 Aluminium Sheet
Lub cev muaj zog piav qhia txog cov yam ntxwv ntawm cov hlau.

Ceev:
Zoo li feem ntau cov txhuas alloys, 5052 yog lub teeb yuag - txog ib qho -peb qhov ceev ntawm cov hlau - uas yog qhov zoo tshaj plaws hauv kev thauj mus los thiab cov khoom siv nqa tau.
Thermal conductivity:
5052 muaj cov thermal conductivity zoo, ua rau nws haum rau cov cua sov-dissipating daim ntaub ntawv xws li hluav taws xob vaj tse los yog tshav kub exchangers.
Hluav taws xob conductivity:
Nws muab nruab nrab hluav taws xob conductivity. Txawm hais tias tsis zoo li cov khoom siv hluav taws xob zoo li txhuas los yog tooj liab, nws yog qhov tsim nyog rau cov khoom siv hluav taws xob uas yuav tsum tau muaj zog thiab corrosion kuj.
Coefficient ntawm Thermal Expansion:
Qhov kev nthuav dav ntawm txhuas yuav tsum tau txiav txim siab nyob rau hauv cov qauv raug kub hloov pauv los yog thaum sib txuas aluminium nrog lwm cov ntaub ntawv.
