Yuav ua li cas xam Aluminium Sheet Weight: 4×8, 1/8″, 3mm & Ntau (Nrog Formula)
Yog tias koj muab cov ntawv txhuas rau fabrication, kev tsim kho, los yog kev tsim khoom, paub yuav ua li cas xam qhov hnyav ntawm ib daim ntawv yog qhov tseem ceeb. Qhov hnyav txiav txim tus nqi thauj khoom, cov qauv load txwv, cov kev cai tuav cov khoom, thiab - qhov tseem ceeb - koj tus nqi ntawm ib chav tsev thaum koj yuav los ntawm tus tuj.
Txawm li cas los xij, ntau tus neeg yuav khoom cia siab rau cov cai ntawm tus ntiv tes xoo lossis tus neeg muag khoom kwv yees uas tuaj yeem tawm ntawm 5-10%. Phau ntawv qhia no muab cov qauv qhia meej rau koj, ib lub rooj ceev-reference rau qhov ntau thiab tsawg, thiab cov alloy tshwj xeeb ceev qhov tseem ceeb koj yuav tsum xam qhov hnyav nrog kev ntseeg siab.
Tus Qauv Ntsuas Qhov Ntsuas
Kev xam qhov hnyav ntawm ib daim ntawv txhuas yog ncaj nraim thaum koj muaj cov qauv tsim nyog. Qhov hnyav ntawm ib daim hlau tiaj tus yog:
Qhov hnyav (kg) = Ntev (m) × Dav (m) × Thickness (mm) × Ceev (g/cm³)
Vim li cas qhov no ua haujlwm: Thaum koj muab qhov ntev × dav × thickness, koj tau txais qhov ntim hauv cubic meters (m³). Muab ntau los ntawm qhov ceev hauv g / cm³ hloov lub ntim rau kilograms vim 1 g / cm³ = 1000 kg/m³, thiab lub mm-rau-m hloov dua siab tshiab rau thickness yog twb accounted rau hauv cov qauv qauv.
Xwb, yog tias koj nyiam ua haujlwm hauv ntiv tes thiab phaus:
Qhov hnyav (lb) = Ntev (hauv) × Dav (hauv) × Thickness (hauv) Txoj ntsiab lus 0.098 (lb/in³ rau txhuas)
Aluminium Density los ntawm Alloy
Tsis yog txhua qhov txhuas muaj qhov ntom ntom. Alloying ntsiab hloov qhov ntom me ntsis, thiab rau kev xam meej - tshwj xeeb tshaj yog thaum tus nqi txiav txim siab - koj yuav tsum siv tus nqi tshwj xeeb alloy:
| Alloy | Qhov ntom (g/cm³) | Siv dav |
| 1050 / 1060 / 1100 (huv) | 2.70 - 2.71 | Daim ntawv dav dav, lub poom mov ua noj, Cov Khoom Siv Tshuaj |
| 3003 / 3004 | 2.72 - 2.73 | Lub vov tsev, nyiaj npluv, ntim khoom noj |
| 5005 | 2.69 | Anodized ntawv, Kev Tsim Kho |
| 5052 | 2.68 | Tubrog nkoj, Lub Cev Lub Cev, general fabrication |
| 5083 / 5086 | 2.66 | Nkoj nkoj, marine structures |
| 5754 | 2.67 | Automotive, pem teb, siab |
| 6061 / 6063 | 2.70 | Cov qauv tsim, tshuab, extrusion |
| 7075 | 2.81 | Aerospace, kev siv zog siab |
Txoj cai ceev: Rau feem ntau ua lag luam aluminium ntawv (1000, 3000, 5000, 6000 series), koj tuaj yeem siv yam xyuam xim 2.70 g/cm³ raws li lub hauv paus. Qhov txawv yog feem ntau tsawg dua 1.5%, uas yog nyob rau hauv ib txwm raug kam rau ua.
Daim Ntawv Loj thiab Lawv Qhov hnyav
Daim ntawv 4 × 8 ko taw (1219 mm × 2438 mm) yog tus qauv kev lag luam hauv North America thiab ntau lub lag luam xa tawm. Hauv qab no yog cov lus ceeb toom ceev ceev rau cov thicknesses feem ntau, xam siv 2.70 g/cm³:
| Thickness | mm | Qhov hnyav rau 4 × 8 daim ntawv (kg) | Qhov hnyav rau 4 × 8 daim ntawv (lb) | Daim ntawv ib metric ton |
| 0.020″ (0.5 mm) | 0.50 | 4.02 | 8.86 | 249 |
| 0.032″ (0.8 mm) | 0.81 | 6.51 | 14.35 | 154 |
| 0.040″ (1.0 mm) | 1.02 | 8.20 | 18.08 | 122 |
| 0.063″ (1.6 mm) | 1.60 | 12.86 | 28.35 | 78 |
| 1/16″ (1.59 mm) | 1.59 | 12.78 | 28.18 | 78 |
| 0.090″ (2.3 mm) | 2.29 | 18.41 | 40.59 | 54 |
| 1/8″ (3.18 mm) | 3.18 | 25.55 | 56.33 | 39 |
| 3/16″ (4.76 mm) | 4.76 | 38.26 | 84.35 | 26 |
| 1/4″ (6.35 mm) | 6.35 | 51.05 | 112.55 | 20 |
| 3/8″ (9.53 mm) | 9.53 | 76.66 | 169.01 | 13 |
| 1/2″ (12.7 mm) | 12.70 | 102.17 | 225.25 | 10 |
Muab xam raws li 1219 Txoj ntsiab lus 2438 mm daim ntawv loj thiab 2.70 g/cm³ ceev. Qhov hnyav tiag tiag tuaj yeem sib txawv ± 2% vim kev tsim khoom thiab qhov sib txawv ntawm alloy.
Step-by-Step Piv piv txwv
Cia peb taug kev los ntawm qhov piv txwv tiag tiag. Piv txwv li, koj yuav tsum xam qhov hnyav ntawm 5052-H32 txhuas ntawv, 4× 8 ft, 1/8 nti tuab:
- Hloov qhov ntev mus rau metric: Ntev: 8 ft = 2438 mm = 2.438 m; Dav: 4 ft = 1219 mm = 1.219 m; Thickness: 1/8 hauv = 3.175 mm
- Nrhiav qhov ntom: 5052 hlau = 2.68 g/cm³
- Siv cov qauv: Hnyav = 2.438 Txoj ntsiab lus 1.219 Txoj ntsiab lus 3.175 Txoj ntsiab lus 2.68 = 25.29 kg
- Hla-kos nrog lub rooj: Lub rooj qhia 25.55 kg pe 2.70 g/cm³. Siv 5052 qhov ceev ntawm 2.68 muab 25.29 kg - qhov sib txawv ntawm txog 1%, uas yog qhov peb xav tau.
Nyhav vs. Tus nqi: Vim li cas qhov no tseem ceeb rau Kev Muag Khoom
Aluminium nplooj ntawv yuav luag txhua tus nqi los ntawm qhov hnyav (USD/kg los yog USD/ton). Thaum koj tau txais ib nqe lus, koj yuav tsum tau xyuas kom meej tias qhov hnyav uas tau hais yog qhov hnyav ntawm cov khoom koj yuav. Nov yog vim li cas:
- Overstated nyhav = overpayment. Qee cov neeg muag khoom hais qhov ntsuas qhov hnyav uas suav nrog kev ua siab ntev (E.G., +5%). Yog koj them rau 1000 kg mas tau 950 kg, koj tau them nyiaj dhau los 5%.
- Shipping nqi xam. Freight yog them los ntawm qhov hnyav los yog volumetric hnyav, qhov twg yog qhov siab dua. Paub qhov tseeb daim ntawv hnyav pab koj kwv yees tag nrho cov nqi tsaws.
- Tus qauv tsim. Yog tias koj tab tom tsim cov qauv (lub ru tsev, trailer lub cev, platform), qhov tuag load ntawm cov ntawv txhuas cuam tshuam rau koj cov kev suav engineering.
- Kev tswj cov khoom muag. Paub tias muaj pes tsawg daim ntawv haum rau hauv ib lub thawv (20ft or 40 ft) pab koj npaj kev txiav txim thiab tsis txhob nyob rau hauv- los yog over-shipping.
Muaj pes tsawg daim ntawv haum rau hauv ib lub thawv?
Siv cov ntaub ntawv hnyav saum toj no, koj tuaj yeem kwv yees lub thawv ntim khoom:
- 20ft thawv: ~ 25,000 kg payload muaj peev xwm → kwv yees li 980 cov ntaub ntawv 1/8″ (25.5 kg ib), los yog ~ 490 nplooj ntawm 1/4″ (51 kg ib)
- 40ft thawv: ~ 28,000 kg payload → kwv yees 1,100 cov ntaub ntawv 1/8″, los yog ~ 550 nplooj ntawv ntawm 1/4″
Tsab ntawv: Volumetric txwv yuav txwv kev thauj khoom rau cov ntawv nyias nyias. Nco ntsoov xyuas nrog koj tus neeg xa khoom xa tuaj.
Feem ntau yuam kev kom zam
- Siv qhov ceev tsis raug. Siv 2.70 rau 7075 (2.81) underestimates hnyav los ntawm 4%. Rau high-zog alloys, ib txwm siv qhov ceev kom raug.
- Tsis meej pem gauge nrog ntiv tes. “16 ntsuas” Aluminium yog 0.051″ (1.29 mm), tsis yog 1/16″ (0.0625″). Kev ntsuas cov qauv sib txawv ntawm txhuas thiab hlau - tsis txhob xav tias lawv zoo ib yam.
- Ignoring kam rau ua. Daim ntawv thickness muaj kev kam rau ua (Feem ntau ± 0.05 hli lossis ± 5%). A “3 mm” daim ntawv tej zaum yuav yog 2.85-3.15 mm, cuam tshuam qhov hnyav nce mus txog 5%.
- Tsis nco qab tiv thaiv zaj duab xis. Qee cov ntawv tuaj nrog PVC tiv thaiv zaj duab xis, uas ntxiv qhov hnyav me me (feem ntau negligible, tab sis tsim nyog sau cia rau precision xam).
- Rounding ntxov dhau. Khaws tag nrho qhov tseeb los ntawm kev suav thiab ib puag ncig tsuas yog cov lus teb kawg nkaus xwb. Rounding nruab nrab cov kauj ruam tuaj yeem ua qhov yuam kev.
Ceev Reference: Hloov ua lwm yam rau mm
| Ntsuas | Ntiv | mm | 4× 8 Qhov hnyav (kg) |
| 20 | 0.032″ | 0.81 | 6.51 |
| 18 | 0.040″ | 1.02 | 8.20 |
| 16 | 0.051″ | 1.29 | 10.37 |

Kev suav cov ntawv txhuas hnyav yog ib qho yooj yim tab sis kev txawj ntse tseem ceeb rau txhua tus neeg yuav khoom, muag, los yog fabricates aluminium. Nrog rau cov mis hnyav = Length × Dav × Thickness × Density, lub rooj alloy density, thiab daim ntawv qhia ceev-reference saum toj no, koj tuaj yeem suav cov ntawv loj hauv vib nas this - tsis muaj kev kwv yees ntxiv lossis tso siab rau kwv yees cov khoom lag luam.
Hauv Eco Alum, peb muab cov ntawv txhuas txhuas hauv cov alloys 1050, 1060, 1100, 3003, 5005, 5052, 5083, 5754, 6061, thiab ntau dua, hauv 4x8, 4× 10, thiab kev cai loj los ntawm 0.5 mm rau 200 Mm tuab. Txhua qhov khoom xa tuaj suav nrog daim ntawv pov thawj kuaj khoom (MTC) nrog qhov tseeb ntsuas thickness thiab qhov hnyav. Tiv tauj peb rau kev sib tw nqe lus ntawm koj qhov kev txiav txim tom ntej.
