Product Description
Engineered specifically for high-temperature cooking applications, our 4xxx series aluminum strips (including 4043, 4343, and 4032) offer uniform heat distribution and excellent oxidation resistance at elevated temperatures. These strips feature Al-Si alloys with silicon content ranging from 4.5–12%, which enhances heat stability and prevents deformation even under continuous use up to 300°C. With customizable thicknesses (0.5–4 mm) and food-safe surface treatments (non-stick coatings, ceramic layers), they are widely used in cookware, bakeware, and industrial heating components where safety and performance are critical.
Parameter | Range |
Alloy Types | 4043, 4343, 4032 |
Thickness | 0.5–4 mm (customizable) |
Width | 100–1500 mm |
Heat Resistance | ≤300°C (continuous use) |
Thermal Conductivity | 150–170 W/m·K |
Tensile Strength | 120–200 MPa |
Uniform Heat Transfer: High silicon content creates a homogeneous microstructure that ensures even heating across pan surfaces, eliminating hot spots and reducing the risk of food burning.
High-Temperature Oxidation Resistance: Forms a self-healing oxide layer (SiO₂) at high temperatures, preventing rusting and maintaining structural integrity during prolonged use in ovens and stovetops.
Food-Safe Coatings:
PTFE (Teflon) Coatings: FDA-approved for direct food contact, with 2–3 μm thickness and scratch resistance up to 3H pencil hardness.
Ceramic Coatings: PFOA-free, scratch-resistant (up to 5H pencil hardness), and heat-resistant up to 450°C, ideal for healthy, low-oil cooking.
Cookware-Specific Customization:
Bonded Layers: Sandwich construction with aluminum-copper-aluminum (ACA) layers to enhance thermal conductivity by 20–30% compared to single-layer aluminum.
Pre-cut Blanks: Laser-cut shapes (round, square, rectangular) for pans, lids, and bakeware molds with ±0.1 mm dimensional tolerance.
Cookware: Frying pans, sauté pans, pressure cookers, grilling plates, and woks for household and commercial kitchens.
Bakeware: Oven trays, muffin tins, cake pans, pizza stones, and bread molds.
Industrial Heating: Heat exchanger fins, furnace liners, and hot plate surfaces.
Automotive: Exhaust manifold heat shields and engine compartment heating components.
Q: Can these strips withstand induction cooking?
A: Yes, when bonded with a 0.3–0.5 mm ferromagnetic layer (e.g., 430 stainless steel), our strips are fully induction-compatible, with heating efficiency ≥90%.
Q: What is the maximum coating durability?
A: PTFE coatings last 2–5 years with proper use (avoiding metal utensils), while ceramic coatings offer 5–8 years of wear resistance under regular cooking conditions.
Q: Do you provide food safety certifications?
A: Yes, all coatings meet FDA 21 CFR 175.300 (USA), EU 10/2011 (Europe), and LFGB (Germany) standards for food contact materials.
Q: Can you produce non-stick strips with custom patterns?
A: Yes, we offer textured non-stick surfaces (e.g., honeycomb, diamond patterns) to reduce food adhesion and improve oil distribution.
Combine with our 4xxx series cast aluminum for heavy-duty cookware bodies, or our food-grade silicone handles (heat-resistant up to 230°C) for ergonomic, safe gripping. For bulk orders, our in-house coating line ensures consistent quality and quick turnaround (1–2 weeks for standard coatings).
