0.22-0.5mm AA5182 Grade Aluminium Coil
0.22–0.5mm AA5182 Grade Aluminium Coil: A "Formability-First" Material for High-Speed Production
When customers choose 0.22–0.5mm AA5182 aluminium coil, they're rarely buying "metal thickness" alone-they're buying stable forming behavior at scale. From a practical manufacturing viewpoint, AA5182 is best understood as a process-friendly alloy: it protects yield, reduces scrap risk, and stays consistent when your press, line speed, or forming depth gets demanding.
Why AA5182 (Not Just Any 5xxx Alloy)?
AA5182 is a magnesium-containing, non-heat-treatable aluminium alloy known for a strong balance of:
- Excellent formability (especially for complex drawing and shaping)
- Good strength versus softer 1xxx/3xxx grades at the same thickness
- Strong corrosion resistance, especially in humid or mildly aggressive environments
- Good weldability for downstream joining needs
Distinctive viewpoint: AA5182 is often chosen not because it is the strongest alloy, but because it is predictably "well-behaved" in forming-a major advantage in high-speed production where variations become expensive.
What 0.22–0.5mm Thickness Really Signals
This thickness range sits in a "sensitive zone" where small changes in material behavior show up quickly as:
- edge cracking during forming
- waviness and poor flatness affecting feeding
- surface marks appearing after coating or printing
- coil set influencing stamping stability
That's why customers using 0.22–0.5mm usually prioritize:
- tight thickness tolerance
- stable mechanical properties across the coil
- controlled surface quality suitable for finishing
Typical Tempers and Practical Implications
AA5182 coil is commonly supplied in tempers such as:
- O (annealed): maximum ductility for deep drawing and aggressive forming
- H111/H112: light work-hardened, offering a controlled strength increase while retaining good formability
- H19/H38 (where applicable by requirement): higher strength, used when stiffness matters more than deep formability
Buying tip: If your process includes deep drawing, redraw, or complex shaping, choose a temper strategy that prioritizes elongation and uniformity, not just tensile strength.
Where Customers Commonly Use 0.22–0.5mm AA5182 Coil
Because it performs well in forming and resists corrosion, this product is a strong fit for:
- automotive inner panels and formed components
- packaging and closures (where formability and consistency matter)
- appliance and light housing parts
- general stamping applications requiring reliable drawability
(Exact suitability depends on temper, surface finish, and forming depth.)
What to Confirm Before You Place an Order (Fast Checklist)
To buy smart-and avoid "looks-right-but-runs-wrong" material-confirm these points:
- Temper & mechanical targets: tensile strength, yield strength, elongation
- Thickness tolerance & coil profile: flatness, crown, edge condition
- Surface requirement: mill finish or treated surface; one-side/two-side quality level
- Coil ID/OD & weight: matching your decoiler and line setup
- Application notes: deep drawing, coating/printing, welding-each needs different priorities
The Bottom Line
0.22–0.5mm AA5182 aluminium coil is a "production-performance" choice: it's selected for consistent formability, reliable strength, and corrosion resistance in a thin-gauge range where quality control matters most. If your goal is fewer forming surprises and smoother high-speed output, AA5182 is often the safer, more scalable option.
