EN573 3000 Grade 3004 Aluminium Coil EN AW 3004 Sheet Coil Used For Packages
3004 aluminum alloy coil is a medium-strength, non-heat-treatable alloy primarily
composed of manganese and magnesium. It offers better strength than pure aluminum while maintaining good formability, weldability, and corrosion resistance.
Mechanical Properties (Typical)
| Temper | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) | Hardness (Brinell HB) |
| O | 150–180 | 70–100 | 20–25 | 40–50 |
| H32 | 190–220 | 160–180 | 8–12 | 55–65 |
| H34 | 210–240 | 180–200 | 6–9 | 60–70 |
✅ Stronger than 1100 / 3003.
✅ Good formability (can be deep draw, spun, or stamped).
✅ Weldable (TIG, MIG, resistance welding).
✅ Corrosion resistance (suitable for humid/coastal environments).
Limitations
❌ Not as strong as heat-treatable alloys (e.g., 6061).
❌ Lower fatigue resistance compared to 5000/6000 series.
❌ Poor machinability
