1070 is a commercially pure aluminum (minimum 99.7% Al) with excellent electrical/thermal conductivity, corrosion resistance, and workability, but lower strength compared to alloyed grades like 3003 or 6061. It is commonly used in electrical, thermal, and lightweight structural applications.
| Element | Composition (%) |
|---|---|
| Aluminum (Al) | ≥ 99.70 |
| Iron (Fe) | ≤ 0.25 |
| Silicon (Si) | ≤ 0.20 |
| Copper (Cu) | ≤ 0.03 |
| Manganese (Mn) | ≤ 0.03 |
| Zinc (Zn) | ≤ 0.03 |
| Others (each) | ≤ 0.03 |
Key Features:
High purity (99.7%+ Al) → Superior electrical/thermal conductivity.
Soft & ductile → Easy to form, bend, and weld.
Low strength → Not suitable for high-stress applications.
| Temper | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) | Hardness (HV) | Primary Use Case |
|---|---|---|---|---|---|
| O (Annealed) | 60 – 80 | 20 – 30 | 35 – 45 | 18 – 25 | Deep drawing, electrical conductors |
| H12 | 80 – 100 | 70 – 80 | 15 – 20 | 25 – 35 | Light structural tubing |
| H14 | 90 – 110 | 80 – 90 | 10 – 15 | 30 – 40 | Moderate-strength tubing |
| H16 | 100 – 120 | 90 – 100 | 6 – 10 | 35 – 45 | Higher rigidity, limited forming |
| H18 (Full Hard) | 110 – 130 | 100 – 110 | 4 – 6 | 40 – 50 | Stiff tubing, minimal bending |
Notes:
O temper is the softest (best for bending, welding).
H18 is the strongest but least ductile (may crack if overworked).
Lower strength than alloyed grades (e.g., 3003, 5052).
✅ Electrical Conductivity – ~62% IACS (ideal for busbars, cables).
✅ Thermal Conductivity – ~230 W/m·K (better than alloyed Al).
✅ Corrosion Resistance – Excellent (pure Al forms a protective oxide layer).
✅ Formability – Excellent (easy to bend, stamp, weld).
❌ Low Strength – Not suitable for load-bearing structures.
Electrical conductors (busbars, cable sheaths).
Heat exchangers & cooling tubes (high thermal conductivity).
Decorative/architectural tubing (easy to polish/anodize).
Food/pharmaceutical packaging (non-toxic, corrosion-resistant).
Chemical industry tubing (resists acids/alkalis).
ASTM B210 / B483: Seamless & welded tubes.
GB/T 4437 (China): Pure aluminum tubes.
EN 573 / EN 754: European standards.
| Alloy | Advantages over 1070 | Disadvantages |
|---|---|---|
| 1070 | Best conductivity, formability | Very low strength |
| 3003 | Higher strength (Mn alloyed) | Lower conductivity |
| 5052 | Much stronger, good corrosion resistance | More expensive |
| 6061 | Heat-treatable, structural strength | Poor conductivity |
