5052 Series Aluminium yog dab tsi?
5052 yog qhov siv ntau tshaj 5xxx-series aluminium-magnesium alloy, muaj 2.2-2.8% magnesium ntxiv rau me me chromium ntxiv. Vim tias nws yog ib qho uas tsis yog - cua sov- kho tau alloy, nws lub zog yog tsim los ntawm kev ua haujlwm txias, uas ua rau muaj ntau yam H tempers . 5052 paub txog kev tiv thaiv corrosion zoo heev, siab qaug zog, zoo heev weldability thiab txaus nyiam economics, uas yog vim li cas nws tshwm nyob rau hauv lub tsheb lub cev, marine Cheebtsam, roj tso tsheb hlau luam, tread phaj thiab dav hlau ua hauj lwm.
Nkag siab H2x thiab H3x Tempers
H tempers piav qhia txog hom kab mob - cov mob hnyav. H3x tempers xws li H32 yog strain hardened thiab ces stabilized nrog ib tug tsawg-kub thermal kho, uas yog tus qauv txoj kev rau magnesium- bearing alloys thiab muab cov khoom ruaj khov tshaj plaws. H2x tempers xws li H22 yog qhov hnyav hnyav dua thiab tom qab ntawd ib nrab annealed mus rau qib uas xav tau. Ob txoj kev tuaj yeem ncav cuag cov chav kawm muaj zog zoo sib xws, tab sis kev ua haujlwm txawv, thiab H22 thiab H24 feem ntau raug kho raws li kev hloov pauv nrog cov kev txwv me ntsis.
5052-H32 vs 5052-H22: Khoom thiab Kev Xaiv
| Khoom | 5052-H32 (tus qauv) | 5052-H22 (tus qauv) |
|---|---|---|
| Chav kawm muaj zog | Lub quarter nyuaj, stabilized | Lub quarter nyuaj, ib nrab annealed |
| Tensile zog Rm | 210-260 MPa (31-38 ksi) | ≈172–241 MPa (25–35 ksi) |
| Yield zog Rp0.2 | Ntau tshaj lossis sib npaug ntawm 130 MPa; Tus qauv yog ≈193 MPa | ≈70-160 MPa los ntawm kev ntsuas |
| Elongation A50 | ≈7–12% | Siab dua, txhim kho ductility |
| Hom kev muab khoom | Daim ntawv, phaj, coil | Coil, ntawv (hloov temper) |
H32 yog qhov feem ntau tau teev tseg 5052 npau taws vim tias nws cov khoom ruaj khov thiab txhais tau meej hauv ASTM B209 thiab EN 485-2. H22 muab kev pabcuam zoo sib xws nrog kev ua haujlwm zoo dua; vim tias nws cov kev txwv tau so, cov neeg yuav khoom yuav tsum tau hais txog qhov xav tau tiag tiag kom lub zeb muab cov kev xav tau.
Mechanical thiab Physical Data rau Common 5052 Tempers
| Kub | Tensile Rm (MPa) | Tawm tswv yim Rp0.2 (MPa) |
|---|---|---|
| 5052-O | 170–215 | Ntau dua lossis sib npaug li 65 |
| 5052-H32 | 210–260 | Ntau dua lossis sib npaug rau 130 (ib txwm ≈193) |
| 5052-H34 | 235–285 | Ntau dua los yog sib npaug rau 180 |
| 5052-H36 | 255–305 | Ntau dua lossis sib npaug li 200 |
| 5052-H38 | Ntau dua lossis sib npaug li 270 | Ntau tshaj los yog sib npaug rau 220 |
Qhov ceev yog 2.68 g / cm3; thermal conductivity nyob ib ncig ntawm 138 W / m-K hauv H32; melting ntau li ntawm 607-649 degrees Celsius. Cov txiaj ntsig yog qhov raug thiab sib txawv nrog cov ntsuas thiab cov txheej txheem tswj hwm.
