5083 Fatigue Limit:160 MPa (10⁷ cycles) -45%siab duaua 5052
Case Study:
Lub tsheb txaj hauv pem teb loaded / unloaded peb zaug ib hnub twg muaj roughly 33,000 cycles tshaj 30 xyoo.
Siv5052, tsim kev nyuaj siab yuav tsum<55 MPa.
Siv5083, kev ntxhov siab tuaj yeem ncav cuag 80 MPa- tso caithinner daim hlau los yog hnyav dua.
Impact Toughness
Impact toughness ntsuas tsis kam rau qhov cuam tshuam tam sim ntawd, tseem ceeb rau kev sib tsoo- cov qauv yooj yim.
5052:25-35 J ntawm chav tsev kub, poob rau 15-25 J ntawm -40 ° C.
5083:30-40 J ntawm chav tsev kub, tswj 25-35 J ntawm -40 ° C.
Qhov tseem ceeb Advantage:
5083tuav zoo heev toughness nyob rau hauv qis kub (polar los yog lub caij ntuj no tej yam kev mob), txo txoj kev pheej hmoo ntawm nkig tsis ua hauj lwm.
Ntev -Lub Sij Hawm Durability
Creep Performance
Creep yog hais txog cov yas deformation qeeb nyob rau hauv lub sij hawm ntev - kev ntxhov siab thiab kub siab.
5052: No creep issues below 80°C for long-term use (>5 xyoo).
5083:ruaj khov hauv qab 65 degree; Lub sijhawm ntev raug tshaj 65℃tuaj yeem ua rau - nag lossis daus theem- sivH321 kubrau kev nyab xeeb.
Tswv yim Engineering:
Rau cov ntawv thov saum toj 50℃(xws li, dej kub lossis HVAC systems), txo cov kev ntxhov siab tsim los ntawm20–30%.
Corrosion-Txoj kev sib cuam tshuam
Nyob rau hauv cyclic loading nyob rau hauv corrosive ib puag ncig, qaug zog lub neej ho txo.
5052 hauv dej hiav txwv:Lub zog qaug zog poob los ntawm 110 txog 70-80 MPa (–27–36%)
5 083:ua.Lub zog qaug zog poob los ntawm 160 txog 110-120 MPa (-25-31%)
Kev daws:Siv anodizing los yog coatings los kho85–90%ntawm qaug zog zog piv rau qhuav tej yam kev mob.
