وصف
Aluminized Coil is produced by coating carbon steel with an aluminum-silicon alloy through a continuous hot-dip process. The material combines the strength of steel with excellent heat resistance, مقاومة الأكسدة, والحماية من التآكل. يستخدم على نطاق واسع في أنظمة عوادم السيارات, معدات التدفئة الصناعية, construction materials, and HVAC applications.
One of the most important considerations when selecting aluminized steel products is choosing the appropriate thickness, width, and coil dimensions for the intended application.
Common Thickness Range
The thickness of aluminized coil varies according to industry requirements.
| سماكة (مم) | سماكة (كَيّل) | التطبيقات النموذجية |
|---|---|---|
| 0.30–0.50 | 29–24 Gauge | قنوات التهوية, appliance panels |
| 0.50–0.80 | 24–21 Gauge | Exhaust components, أنظمة التدفئة والتهوية وتكييف الهواء |
| 0.80–1.20 | 21–18 Gauge | Industrial equipment |
| 1.20–2.00 | 18–14 Gauge | الدروع الحرارية, الأجزاء الهيكلية |
| 2.00–3.00 | 14–11 Gauge | Heavy-duty industrial applications |
Common Width Specifications
Most manufacturers offer standard widths suitable for coil processing and sheet production.
| عرض (مم) | عرض (بوصة) |
| 600 | 23.6 |
| 914 | 36 |
| 1000 | 39.4 |
| 1219 | 48 |
| 1250 | 49.2 |
| 1500 | 59 |
| 1524 | 60 |
Custom widths can also be slit according to customer requirements.
Coil Dimensions
| غرض | النطاق النموذجي |
| Inner Diameter | 508 مم / 610 مم |
| القطر الخارجي | 1000–2000 mm |
| وزن الملف | 3–25 Tons |
| Coil Length | Customized |
The actual coil dimensions depend on thickness, width, and transportation requirements.
Common Coating Weights
The aluminum-silicon coating weight affects corrosion resistance and service life.
| Coating Grade | Total Coating Weight (جم/م²) |
| AS60 | 60 |
| AS80 | 80 |
| AS100 | 100 |
| AS120 | 120 |
| AS150 | 150 |
Higher coating weights generally provide enhanced durability and oxidation resistance.
Typical Production Tolerances
| مواصفة | Typical Tolerance |
| سماكة | ±0.02–0.05 mm |
| عرض | ± 2 مم |
| طول | ±3 mm |
| Flatness | According to standard requirements |
Precise tolerances help ensure stable performance during stamping, الانحناء, and welding operations.
Popular Sizes in Industrial Applications
| سماكة (مم) | عرض (مم) |
| 0.47 | 1219 |
| 0.60 | 1219 |
| 0.80 | 1219 |
| 1.00 | 1219 |
| 1.20 | 1219 |
| 1.50 | 1250 |
| 2.00 | 1500 |
These dimensions are commonly used for automotive exhaust systems, industrial furnace components, ventilation equipment, and heat-resistant fabrication projects.
