Core Difference Analysis
1. Kev ua tau zoo sib txawv
- Cov ntsiab lus Silicon
ADC12 siab dua Si (9.6-12% vs. 7.5-9.5%):
- Txhim khu fluidity rau nyias-phab ntsa tuag casting (xws li, 3C khoom vaj tse)
- A380's qis Si txhim kho tensile zog (+40%) thiab ductility (+150%)
- Cov ntsiab lus tooj liab
A380's siab dua Cu (3-4% vs. 1.5-3.5%):
- Cov ntsiab lus tooj liab
- Boosts high-temperature zog (zoo tagnrho rau cav brackets)
- Txo corrosion kuj (yuav tsum tau kho deg)
- impurity cuam tshuam
ADC12 qhov siab dua impurities (3.5% vs. 2.0%):
- impurity cuam tshuam
- Nce porosity los ntawm 15-20%
- Txo thermal conductivity 10-15% (tseem ceeb rau cov dab dej kub)
2. Txheej txheem Compatibility
| Txheej txheem | ADC12 tsim nyog | A380 Kev tsim nyog |
| High-pressure Tuag Casting | ★★★★★ (Optimized) | ★★★★☆ (Parameter hloov kho xav tau) |
| Xuab zeb Casting | ★☆☆☆☆ (Nyob rau kub kua muag) | ★★★★☆ (txoj kev nyiam) |
| Permanent Pwm Casting | ★★☆☆☆ (Qhov yooj yim geometry nkaus xwb) | ★★★☆☆ (Yuav tsum tau txias txias) |
| Nqus Tuag Casting | ★★☆☆☆ (Cov teeb meem impurity) | ★★★★☆ (High air-tightness qhov chaw) |
Daim ntawv thov Scenario
ADC12 Dominant Applications
- AutomotiveValve npog, sensor brackets (1.5-3mm phab ntsa thickness)
- Khoom sivTom ntej: AC compressor vaj tse (cov nqi tsav tsheb)
- General Machinery: Pump casings (tsis yog-load-bearing qhov chaw)
A380 Dominant Applications
- Tsheb ciav hlau: Cav Mounts, kis tau tus mob (kev qaug zog tsis kam)
- Khoom siv: Hydraulic blocks (siab nruj yuav tsum tau)
- Aerospace: Non-structural brackets (lub zog-rau-hnyav optimization)
Foundry kws tshaj lij pom zoo
- Nqi-Driven Projects
- Siv ADC12: Zoo tagnrho rau cov xim pleev xim / electrophoresis (qhov ncauj qhov ntswg porosity)
- Zam rau anodizing (impurity-induced xim variation)
- Kev ua tau zoo-Critical Applications
- Xaiv A380: Ua ke nrog T5 kev kho cua sov (+ 15-20% lub zog)
- Siv pwm tswj qhov kub thiab txias rau cov geometry complex
- Cov txheej txheem tshwj xeeb yuav tsum muaj
- Welded Cheebtsam: Nyiam A380 (qis Si txo qhov kub tawg)
- Thermal tswj qhov chaw: Zam ADC12 (thermal inconsistency)
- Qhov kev sib piv kev ua haujlwm no ua rau cov engineers thiab cov neeg yuav khoom los txiav txim siab cov ntaub ntawv paub tseeb. Raudawb DFM tsom xam templateslos yogcov lus qhia kev tiv thaiv tsis xws luag, tiv tauj peb pab neeg technical.
