Aluminium Sheet Price Per Kg

Product Details
The aluminium sheet price per kg is widely used in industrial procurement because aluminum products are usually quoted by weight. To understand cost estimation correctly, it is important to know how to calculate sheet weight and compare aluminum with stainless steel materials.
aluminum sheet metal is significantly lighter than steel-based materials, which directly affects transportation cost, fabrication cost, and final project pricing.
1. Aluminum Sheet Weight Calculation Formula
The weight of aluminum sheet is calculated using the material density and geometric dimensions.
Basic Formula:
Weight (kg) = Length × Width × Thickness × Density
For aluminum:
- Density ≈ 2.70 g/cm³ = 2700 kg/m³
Simplified Industrial Formula:
Weight (kg) = Area (m²) × Thickness (mm) × 2.7
Example Calculation:
For a 2mm aluminum sheet:
- Area = 1 m²
- Thickness = 2 mm
👉 Weight = 1 × 2 × 2.7 = 5.4 kg/m²
Quick Reference Table:
| Thickness | Weight (kg/m²) |
|---|---|
| 1 mm | 2.7 kg |
| 2 mm | 5.4 kg |
| 3 mm | 8.1 kg |
| 5 mm | 13.5 kg |
| 10 mm | 27 kg |
2. Stainless Steel Weight Comparison
stainless steel sheet is much heavier than aluminum due to higher density.
- Stainless steel density ≈ 7.85 g/cm³
Stainless Steel Weight Formula:
Weight (kg) = Area × Thickness × 7.85
Comparison Table (Same Thickness = 2mm)
| Material | Density | Weight (kg/m²) |
|---|---|---|
| Aluminum | 2.7 | 5.4 kg |
| Stainless steel | 7.85 | 15.7 kg |
👉 Stainless steel is almost 3 times heavier than aluminum.
3. Cost Impact: Aluminium vs Stainless Steel
Because pricing is usually based on kg, weight difference directly affects total cost.
Aluminum Advantages:
- Lower weight → lower shipping cost
- Easier handling and installation
- Lower structural load requirement
- More cost-efficient for large-area projects
Stainless Steel Characteristics:
- Higher strength
- Higher density and weight
- Better wear and heat resistance
- Higher overall material cost per sheet in many applications
4. Application Difference Based on Weight
Aluminum Sheet Applications:
aluminum sheet metal
- Transportation panels
- Architectural cladding
- HVAC systems
- Lightweight structures
- Marine components
Stainless Steel Sheet Applications:
stainless steel sheet
- Food processing equipment
- Chemical industry tanks
- High-temperature environments
- Decorative durable surfaces
- Heavy-duty industrial structures
5. Key Difference Summary
| Feature | Aluminum Sheet | Stainless Steel Sheet |
|---|---|---|
| Density | Low | High |
| Weight | Light | Heavy |
| Cost per kg | Lower | Higher |
| Fabrication | Easy | Strong but harder |
| Corrosion resistance | Good | Excellent |
