In the kitchenware manufacturing industry, 3000 series aluminium alloys (such as 3003, 3004, and 3005) have become one of the most popular materials due to their excellent strength, corrosion resistance, and machinability. Whether for household cookware, baking moulds, or commercial kitchen equipment, 3000 series aluminium alloys have secured a central position in the industry due to their high cost-effectiveness, safety, and durability.
Physical Performance Advantages of 3000 Series Aluminium
3000 series aluminium alloys (such as 3003, 3004, and 3005) have become the ideal material for modern kitchenware manufacturing due to their unique manganese (Mn) strengthening properties.
Lightweight and Strength Balance
With a density of just 2.73 g/cm³, it is 66% lighter than stainless steel, giving kitchenware a lightweight design. This not only reduces transportation costs but also significantly reduces the weight of kitchenware, making single-handed operation more effortless. The manganese (Mn) reinforcement achieves a tensile strength of 150–220 MPa. For example, a wok can withstand 100,000 stir-fries without deformation.
Excellent Thermal Conductivity
The 3000 series aluminium has a thermal conductivity of up to 220 W/(m·K). As kitchenware, it heats up three times faster than stainless steel and saves 15% energy.Additionally, experiments have proven that the temperature uniformity of 3000 series aluminium kitchenware is outstanding: the temperature difference between the centre and edge of a frying pan is ≤8°C. Its exceptional performance makes it an economical and efficient choice.
Food-grade corrosion resistance
The food-grade corrosion resistance of 3000 series aluminium meets food safety standards such as FDA, GB 4806.9, and LFGB. The natural oxide film and manganese (Mn) elements work synergistically to ensure no perforation after 500 hours of salt spray testing.
Superior processing performance of 3000 series aluminium
Exceptional plastic deformation capability, capable of handling various shapes with ease
3000 series aluminium in the H24 condition maintains an elongation rate of 8-12%, balancing strength and formability. It can easily achieve complex processes such as deep drawing and spinning. 3003 aluminium circle plates can achieve a depth-to-diameter ratio of 1:1.5, enabling one-piece moulding for soup pots and significantly reducing scrap rates.
Outstanding precision punching performance, significantly increasing processing efficiency
No secondary grinding is required on the edges of kitchenware, reducing processing steps. Additionally, the shear strength is only one-third that of stainless steel, with die-cutting energy consumption reduced by 40%. Data on die-cutting gaps, burr height, and surface finish quality all significantly outperform commonly used 304 stainless steel.
Strong compatibility with surface treatments, perfectly suited for various surface treatments
Anodising, coating adhesion, electrolytic polishing, micro-arc oxidation… The 3000 series aluminium discs can easily handle these processes, consistently achieving mirror-like, ceramic-like surfaces, metallic luster, and other surface effects, perfectly suited for various kitchenware manufacturing processes.
