Technical Specifications for Rice Cooker Inner Pots
1. Optimal Aluminum Alloys
- 1050/1060 Pure Aluminum (H24 Temper)
- 99.5% purity for superior thermal conductivity (229 W/m·K)
- Ideal for basic models requiring rapid heat transfer
- 3003 Alloy (H14 Temper)
- Manganese-enhanced strength (+20% vs pure Al)
- Withstands repeated thermal cycling (20,000+ cycles)
2. Thickness Guidelines
| Pot Diameter | Recommended Thickness | Rationale |
|-------------------|----------------------------|---------------------------------|
| 16-18cm (1-3L) | 0.8-1.2mm | Balance heat response & dent resistance |
| 20-22cm (5-8L) | 1.5-2.0mm | Structural stability for larger capacity |
| Pressure Models | 2.2-2.5mm | Withstand 150kPa internal pressure |
3. Critical Surface Treatments
- Anodizing (20-25μm thickness):
- Prevents acidic food corrosion (pH 2.5-8.5 resistance)
- Base layer for PTFE/PFOA-free ceramic coatings
- Diamond-Textured Finish:
- 5-8μm roughness enhances coating adhesion
- Reduces sticking by 40% vs smooth surfaces
