8006 Aluminium Coil Strip
For buyers, the appeal of 8006 aluminium strip coil is straightforward: it runs clean, slits well, holds shape better than softer foil alloys, and supports tight tolerances for modern lamination, stamping, roll forming, and fin punching operations.
Features of 8006 Aluminium Coil Strip
| Feature | What it means in production | Customer value |
|---|---|---|
| Higher strength than 8011/1235 | Fe-Si strengthening improves rigidity and buckle resistance | Better shape retention, fewer line stops, improved converting speed |
| Excellent corrosion resistance | Natural oxide film protects in most atmospheres | Long service life for heat exchangers and packaging |
| Good formability in H14/H24/H22 | Supports bending, shallow drawing, and fin forming | Lower cracking risk, better edge integrity |
| Stable gauge and flatness | Works well with precision rolling and tension leveling | Reduced scrap, consistent downstream performance |
| Clean surface options | Mill finish or degreased/treated as required | Improved coating/lamination adhesion and appearance |
| Recyclable and lightweight | Aluminium circularity and low density | Lower transport cost, sustainability advantages |
Typical Applications
| Industry | Typical use | Why 8006 is chosen |
|---|---|---|
| HVAC & refrigeration | Fin stock for condensers/evaporators | Strength + formability for fine fin pitch and stable louvers |
| Packaging | Container stock, closures, laminated structures | Barrier performance, strength, and process stability |
| Food & household | Trays, lids, light-gauge forming | Good drawability in suitable tempers and reliable surface |
| Industrial converting | Slitting stock, roll-formed profiles | Tight tolerances, consistent edge quality |
Notes for selection: 8006 is frequently specified when a product needs more rigidity than 8011 while still requiring good forming and consistent flatness for high-speed equipment.
8006 is a non-heat-treatable alloy. Mechanical properties are mainly controlled by cold work (H tempers) and optional partial annealing.
| Temper (common) | Condition | Typical use case |
|---|---|---|
| O | Fully annealed | Maximum formability, deep/shallow forming where strength is secondary |
| H14 | Half-hard (strain hardened) | Fin stock and general strip requiring higher stiffness |
| H18 | Full-hard | When maximum strength and rigidity are needed with limited forming |
| H22 | Strain hardened and partially annealed | Balanced strength/elongation, improved forming vs H14 |
| H24 | Strain hardened and partially annealed (higher than H22) | Fin forming and stamping with better crack resistance than H18 |
Temper availability and performance depend on thickness, final gauge, and processing route (rolling schedule, anneal control, surface treatment).
Chemical Composition (Typical / Standard Limits)
8006 chemistry varies slightly by standard (EN, ASTM/AA equivalents and customer specifications). The table below reflects widely used compositional ranges for 8006-type material.
| Element | Typical range (wt.%) | Role in the alloy |
|---|---|---|
| Al | Remainder | Base metal, corrosion resistance, conductivity |
| Fe | 1.2–2.0 | Primary strengthening, improves rigidity |
| Si | 0.3–1.0 | Works with Fe for strength and microstructure control |
| Mn | ≤0.3 | Grain structure support, minor strengthening |
| Cu | ≤0.3 | Strength contribution; kept low for corrosion control |
| Mg | ≤0.1 | Typically low; may affect work hardening slightly |
| Zn | ≤0.1 | Usually limited to preserve corrosion behavior |
| Ti | ≤0.08 | Grain refiner (casting/rolling stability) |
| Others (each) | ≤0.05 | Controlled impurities |
| Others (total) | ≤0.15 | Controlled impurities |
Technical Specifications (Supply Range)
The practical supply window depends on mill capability, end-use, and tolerance class. The table below shows common ranges for coil strip supply.
| Item | Typical supply range | Notes |
|---|---|---|
| Form | Coil / strip | Slit coils available |
| Thickness | 0.05–2.00 mm | Foil-like gauges possible with specific rolling routes |
| Width | 20–1600 mm | Narrow strip slitting to tight edge quality available |
| Inner diameter (ID) | 152 / 300 / 400 / 505 mm | Standard IDs; others by agreement |
| Outer diameter (OD) | Up to ~1200–1800 mm | Depends on thickness and coil weight limits |
| Coil weight | ~0.5–10 t | Typical industrial range; customized possible |
| Surface finish | Mill finish, bright, degreased | Film/lamination-friendly options |
| Edge | Slit edge, mill edge | Slit edge recommended for precision converting |
| Flatness | Tension leveled / as rolled | Defined by application (fin, stamping, lamination) |
| Standards | ASTM / EN / GB or customer spec | Confirm alloy designation and temper mapping |
Typical Mechanical Properties (Reference Values)
Mechanical properties vary with gauge, temper, and test direction. Values below are typical reference ranges used for quick comparison and initial selection.
| Temper | Tensile strength (MPa) | Yield strength (MPa) | Elongation A50 (%) | General behavior |
|---|---|---|---|---|
| O | 60–110 | 20–50 | 20–35 | Highest ductility, lowest strength |
| H22 | 120–170 | 90–140 | 6–15 | Balanced formability and strength |
| H24 | 140–190 | 110–160 | 5–12 | Good strength with improved forming vs hard tempers |
| H14 | 150–200 | 120–170 | 3–10 | Higher stiffness; forming possible with correct radii |
| H18 | 170–230 | 150–200 | 1–6 | Maximum rigidity; limited forming |
If your process includes aggressive fin punching, tight-radius bending, or deep embossing, specifying an appropriate partially annealed temper (H22/H24) often improves yield while keeping sufficient stiffness.

|---|---|---|
| Surface cleanliness | Controlled rolling oil / optional degreasing | Improves coating, printing, and lamination adhesion |
| Pinholes / inclusions | Tight control for thin gauges | Critical for barrier and appearance-sensitive products |
