Aluminum Alloy 3003 Aluminum Circles for Non-stick Pans | Thickness 1.0–4.0 mm | Diameter 150–800 mm | Ceramic or PTFE Coated
Introduction
The 1.0–4.0 mm 3003 aluminum circles (deep drawing quality, ceramic or PTFE coated) are currently the most widely adopted alloy worldwide for the base disc of non-stick fry pans, saucepans, woks, grill pans, induction cookware and multi-layer clad bottoms.
Compared to 1050/1060 (softer & lower strength) or 3004/5182 (stronger but higher cost), 3003 provides the optimal balance for modern non-stick cookware manufacturing:
Mn alloying (1.0–1.5%) → 20–30% higher strength & better dent resistance
Excellent deep-drawing & stretching performance (no orange peel, minimal earing)
Uniform fine grain structure → smooth surface after coating & forming
Very good corrosion resistance to food acids & daily washing
Cost-effective while meeting all major cookware brand quality standards
Coating compatibility:Ceramic (sol-gel or reinforced) — high scratch resistance, metal-utensil safe,PTFE (Teflon® / similar) — classic non-stick, low-friction release,Base circle temper: O / H12 / H14 / H16 (deep drawing optimized)

Advantages
Core Benefits:
| Advantage | Detailed description |
|
Superior Deep-Drawing & Formability |
High elongation & low earing → deep pan bodies without cracks. |
|
Excellent Coating Adhesion & Uniformity |
Smooth surface → even ceramic/PTFE application & no bubbling. |
|
High Strength & Dent Resistance |
Yield 145–195 MPa → better warp resistance than 1xxx series. |
|
Good Food Acid & Detergent Resistance |
No pitting or discoloration after prolonged food contact. |
|
Lightweight yet Rigid Base |
2.0 mm ≈ 5.4 kg/m² → 60% lighter than equivalent stainless. |
|
Induction Compatibility (with clad disc) |
Mn content enables magnetic cladding for induction hobs. |

FAQ (USA/Europe/Middle East/Asia Buyers)
Q1: Why choose 3003 circles over 1050/1060 or 3004 for non-stick pans?
A: 3003 offers 20–30% higher strength & better dent/warp resistance than 1050/1060 while remaining much lower cost than 3004. It has excellent deep-drawing performance and uniform coating adhesion — making it the industry standard for most mid-to-high-end non-stick cookware.
Q2: How does 3003 perform in deep drawing & does it show orange peel or earing?
A: 3003 has very low earing (≤3%) and minimal orange peel due to fine grain control. It achieves deep pan bodies (drawing ratio >2.0) without cracking. We provide deep-draw samples & forming limit diagrams.
Q3: Is 3003 suitable for induction cookware with clad stainless disc?
A: Yes — 3003 is widely used as the base layer in tri-ply / 3-ply induction cookware (stainless / aluminum / stainless). We supply circles pre-bonded or ready for cladding.
Q4: Minimum order quantity & lead time for custom diameter or coating?
A: MOQ 1 ton (depending on diameter); standard sizes 15–25 days; custom diameter or special coating 25–35 days. Sample circles free with freight collect.
Q5: How does 3003 hold up to dishwasher cycles & food acids?
A: Excellent — no pitting or coating degradation after 1000+ dishwasher cycles or prolonged contact with tomato sauce, vinegar, etc. Food-acid immersion & dishwasher test data available.
Q6: Can the circles be embossed or textured before coating for premium look?
A: Yes — 3003 supports light embossing / texturing. We provide embossed + coated samples for non-slip or decorative effects.
