Discover our core raw materials specifically optimized for deep-drawing, thermal conduction, and structural integrity in professional kitchenware systems.
In the global food service industry, cookware is not just a tool; it is a critical instrument of culinary precision. Professional chefs require vessels that heat rapidly, maintain even temperature distribution, resist warping under extreme thermal shocks, and withstand corrosive food acids. This demand has positioned high-grade aluminum stock material as the backbone of professional cookware manufacturing.
The global market for professional kitchen utensils is experiencing a major shift toward energy-efficient, induction-ready, and multi-ply composite structures. Traditional cookware relied heavily on single-layer materials, but modern industrial standards demand cladding technologies where aluminum acts as the high-conductivity core sandwiched between layers of stainless steel. This combination leverages the superior thermal diffusivity of aluminum and the durability of steel.
Moreover, health and safety regulations worldwide are driving manufacturers to source certified food-grade alloys (such as 1050, 3003, and 5052) that undergo strict anodization processes. Anodized aluminum cookware has gained massive commercial traction due to its non-reactive surface, hardness exceeding that of stainless steel, and exceptional wear resistance in high-turnover commercial kitchens.
Hangzhou Chenxing New Energy Technology Co., Ltd. is a core member of Chenxing Aluminium Group. We focus on high-performance green aluminium products, committed to building a sustainable future through advanced production technology and strict quality control. Our main products feature excellent formability, corrosion resistance and environmental performance, widely used in new energy, construction, HVAC and transportation industries. Relying on strong group support and professional R&D capability, we provide stable, reliable and eco-friendly aluminium solutions for global customers.
From high-temperature commercial baking to heavy-duty industrial pressure vessels, see how our aluminum alloys are engineered for specific kitchen demands.
Commercial stock pots require extreme depth and consistent wall thickness. Utilizing our Deep-Drawing Quality (DDQ) aluminum circles (alloys 1050/3003) ensures the material flows smoothly in the press without developing orange-peel defects or thinning at the corners. This guarantees structural integrity under high volume stress.
Modern commercial kitchens utilize induction cooktops for safety and speed. By layering our specialty induction aluminum circles with magnetic stainless steel bases, manufacturers create impact-bonded cookware that responds instantly to electromagnetic fields while distributing heat evenly across the cooking surface.
High-capacity bakeries require sheets that do not warp under rapid temperature changes. Our hard-alloy sheets (such as 3004 and 5052 tempers) offer the perfect balance of tensile strength and thermal conductivity, ensuring thousands of baking cycles without distortion or surface degradation.
Our factories have imported equipment from Germany to produce various green and low-carbon aluminum products from series 1 to series. With annual production capacity of 50000 tons of aluminium coil, strip, sheet, plate, checkered plate, embossed coil, foil and circle. Our facilities include One Hot Rolling line, 15 Casting Lines, 3 Cold Rolling Lines, 3 Transverse Shear Production lines, 3 Tension Levelers, 24 Annealing Furnaces, and 3 Cutting equipment for circle.
Choosing the correct alloy chemical composition and temper properties is vital for achieving the desired thermal response and mechanical strength.
| Alloy Series | Key Characteristics | Common Tempers | Primary Cookware Applications | Thermal Conductivity (W/m·K) |
|---|---|---|---|---|
| 1050 / 1100 | 99.5%+ Pure Aluminum, highly ductile, maximum heat conductivity, excellent corrosion resistance. | O, H12, H14 | Clad metal cores, deep-drawn pots, electric kettle heating plates, light utensils. | 220 - 230 |
| 3003 | Al-Mn alloy, 20% stronger than 1100 series, excellent workability, highly weldable. | O, H12, H14, H24 | Standard professional frying pans, saucepans, non-stick pan substrates, pressure cooker inner liners. | 190 - 200 |
| 3004 | Higher strength than 3003, superior drawing characteristics, excellent structural rigidity. | O, H32, H34 | Commercial baking sheets, heavy-duty frying pans, deep-drawn industrial stock pots. | 180 - 195 |
| 5052 | Al-Mg alloy, high fatigue strength, exceptional corrosion resistance to saline and acidic environments. | O, H32, H34 | Heavy-duty professional kitchen utensils, marine galley cookware, handle rivets, brackets. | 138 - 150 |
Deep-Drawing Quality (DDQ) Control: For deep-drawn cookware, the grain size of the aluminum sheet must be carefully controlled. If the grain size is too large, the surface will develop an "orange peel" texture after drawing, requiring extensive polishing. If too small, the material becomes brittle and prone to tearing. Our advanced German annealing furnaces allow us to control the grain size within an optimal range of 35 to 45 microns, ensuring a flawless mirror finish post-forming.
Our products range covers almost all aluminium alloys series 1xxx to 8xxx, especially 1xxx, 3xxx, 5xxx, 6xxx 7xxx and 8xxx series. With advantages of light weight, great corrosion resistance and easy processing, our products are widely used in packaging, construction, transportation, power and electrical, machining, marine and aerospace industries.
Through rigorous metallurgical testing, precise tension leveling, and advanced shearing, we ensure that every batch of aluminum circles, sheets, and coils delivered to cookware manufacturers meets strict dimensional tolerances (within ±0.05mm) and flatness standards, eliminating line stoppages during automated press runs.
The intersection of culinary performance, environmental responsibility, and advanced metallurgy.
Global consumer brands are facing strict carbon-accounting mandates. Cookware manufacturers are actively seeking aluminum stock produced via renewable energy sources (like hydropower) or high-content recycled materials. Our green production bases utilize clean energy structures to keep the carbon footprint of our aluminum circles and sheets minimal, aiding brands in achieving their ESG goals.
Modern non-stick finishes require precise substrate surface preparation. The aluminum stock must possess a controlled surface roughness (Ra value) to ensure mechanical adhesion of ceramic or PTFE coatings without relying on toxic chemical primers. Our precision-engineered cold rolling lines deliver targeted surface textures optimized for next-generation coating adhesion.
