3. What Is the Price of 25x3mm GI Strip?
A 25x3mm GI (galvanized iron) strip is cheaper than aluminum but heavier and prone to rust.
Here’s a simple comparison:
| Material | Weight (kg/m) | Price (USD/kg) | Corrosion Resistance | Conductivity |
|---|---|---|---|---|
| GI Strip | 0.59 | $0.9 – $1.2 | Poor | Low |
| Aluminum Strip | 0.20 | $2.2 – $3.5 | Excellent | High |
Conclusion: Although GI strip costs less, aluminium strips last longer, especially in outdoor or electrical applications.
4. Is 3mm Thick Aluminium Strong?
Yes. A 3mm aluminum strip provides a good balance between strength and flexibility. The strength depends on the alloy:
| Alloy | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) |
|---|---|---|---|
| 1060 | 60 – 110 | 25 – 80 | 20 – 30 |
| 5052 | 210 – 260 | 130 – 180 | 12 – 20 |
| 6061 | 240 – 290 | 200 – 240 | 8 – 12 |
This makes it ideal for structural framing, decorative trims, electrical connectors, and heat shields.
5. What Is an Aluminum Strip?
An aluminum strip is a flat aluminum product cut from a coil, typically used in:
- Electrical applications (busbars, transformers)
- Automotive manufacturing (heat exchangers, trims)
- Construction (roof edging, wall cladding)
- HVAC (air ducting, insulation covers)
- Signage and decoration
Its benefits include:
- Lightweight (1/3 of steel)
- Excellent thermal and electrical conductivity
- Anti-rust and corrosion-resistant
- Recyclable and eco-friendly
6. What Is the Price of Copper Strip 25×3?
Copper strips are much more expensive than aluminum but have higher conductivity.
| Material | Price (USD/kg) | Conductivity | Density (g/cm³) | Cost Efficiency |
|---|---|---|---|---|
| Copper (25×3) | $8.0 – $10.5 | 100% IACS | 8.96 | Medium |
| Aluminum (25×3) | $2.3 – $3.5 | 61% IACS | 2.70 | High |
Conclusion: Aluminum provides a better price-performance ratio, making it the preferred material for modern electrical and industrial uses.
