When cost reduction is critical without sacrificing basic functionality, these aluminum alloys deliver the best value:
1. 1000 Series (Pure Aluminum)
Representative: GNEE 1050,1060,1100 aluminum
Cost Advantage:
Lowest raw material price (5-10% cheaper than alloys)
Minimal alloying elements (<1% impurities)
Typical Uses:
Food packaging (foil, containers)
Chemical storage tanks
Decorative trims
| Grade | State | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) | Typical Application Scenarios |
|---|---|---|---|---|---|
| 1050 | O | 45–75 | 20–30 | ≥25 | Radiators, circuit board substrates |
| 1100 | H14 | 110–145 | 105–125 | 5–15 | Chemical containers, decorative parts |
| 1060 | O | 70–95 | 25–35 | 25–30 | Conductive parts, reflective panels |
2. 3003 Aluminum (Manganese Enhanced)
Cost-Performance Balance:
20% stronger than pure aluminum
Only 1.2-1.8% manganese addition keeps costs low
Applications:
HVAC systems (heat exchangers)
Truck/trailer siding
DIY projects
| Grade | State | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) |
|---|---|---|---|---|
| 3003 | H112 | 110–145 | 40–60 | 12–20 |
| 3003 | O | 95–130 | 35–50 | 25–40 |
| 3004 | H34 | 200–240 | 170–200 | 6–12 |
3. 5005 Alloy (Magnesium Blend)
Economic Strengthening:
0.5-1.1% magnesium raises strength without chromium/nickel
Priced 15% lower than 6061
Where to Use:
Marine fittings (saltwater resistant)
Architectural panels
Electrical enclosures

Smart Selection Tips
Avoid over-specifying: Use 6061 only when high strength is mandatory
Recyclability matters: 1000-series scrap retains 95% value
Surface treatment savings: 3003 accepts powder coating without pretreatment
Pro Tip: Combine cheap alloys with cost-efficient processes (e.g., 1100 + roll forming) for maximum savings.
