It features optimized aperture shapes and surface treatments to maintain consistent flow and filtration efficiency in demanding environments. Material Types and Their Applications 1. Metal Screens Constructed from high-quality steel, metal screens are ideal for abrasive, coarse, or heavy materials where durability and rigidity are essential. Suitable for: Sand, gravel, crushed stone, ores, coal, and heavy aggregates. Characteristics: High strength, wear-resistant, maintains shape under high impact, rigid and stable. Unique Advantages: Can withstand high temperatures and mechanical stress; ideal for heavy-duty mining and construction operations; long service life with minimal deformation. 2. Polyurethane Screens Polyurethane screens provide flexibility, elasticity, and resistance to wear, making them ideal for sticky or damp materials.

In the modern kitchenware and cookware manufacturing industry, the selection of base materials directly determines the forming quality, thermal conductivity, and service life of the finished product. Food-grade aluminum Circles in 1050, 1060, and 1100 pure aluminum grades, as well as 3003 aluminum-manganese alloy, have become preferred raw materials for manufacturers of non-stick pans, pressure cookers, frying pans, kettles, and baking molds worldwide. This is due to their excellent deep-drawing performance, uniform heat conductivity, and strict food-contact compliance. Food-grade aluminum Circles are circular aluminum blanks made from aluminum sheets or coils through cutting, punching, and forming processes. They are commonly used as raw materials for manufacturing aluminum cookware and kitchen utensils. Common Alloys 1050 Aluminum Disc – High aluminum purity and excellent thermal conductivity. 1060 Aluminum Disc – Excellent thermal conductivity and good formability. 1100 Aluminum Disc – Good corrosion resistance, ductility, and workability. 3003 Aluminum Disc – Higher strength and excellent formability, suitable for more demanding cookware applications. Cookware Aluminum Disc Specifications Parameter:Specification Range Alloy Grade:1050, 1060, 1100, 3003 Temper:O, H12, H14, H16, H18, H22, H24, H26, etc. Thickness:0.2 mm–6.5 mm, customizable Diameter:70 mm–1200 mm, customizable Surface Finish:Mill finish, brushed finish, polished finish Production Process:CC (continuous casting and rolling) / DC (hot rolling) Tolerance:Diameter: ±0.2 mm; Thickness: ±0.02 mm Edge Treatment:Burr-free edge, trimmed edge, rounded edge, etc. Packaging:Moisture-proof paper, plastic film, wooden pallets, wooden cases, or customized export packaging MOQ:3 tons Applications 1050, 1060, 1100, and 3003 aluminum Circles are suitable for manufacturing a wide range of kitchenware and food-contact metal products, including but not limited to: Non-stick frying pans and flat pans Woks, stockpots, and milk pots Pressure cookers and cooker lids Steamers, steaming trays, and steamer inserts Baking trays, cake molds, and pizza pans Aluminum serving trays, food trays, and lunch boxes Kitchen storage containers and food-processing containers Rice cooker inner pot housings and kitchen appliance components Aluminum substrates for multilayer composite cookware Spun cookware, deep-drawn cookware, and anodized cookware Key Product Advantages 1. Lightweight Aluminum has a density of only 2.70 g/cm³, making it lightweight, easy to transport, and easy to process. This helps reduce logistics costs significantly. Cookware made from aluminum is also lighter and better suited to modern ergonomic kitchen requirements. 2. Excellent Deep-Drawing Performance Aluminum Circles offer high plasticity and ductility, making them highly suitable for manufacturing deeply drawn products such as pots and kettles. They are less likely to crack or wrinkle during forming. Optimized for deep drawing and stretching processes, these Circles effectively reduce earing and cracking, thereby minimizing material waste. 3. Efficient Thermal Conductivity Pure aluminum grades, especially 1050 and 1060, provide excellent thermal conductivity, allowing cookware to heat quickly and evenly. This improves cooking performance and energy efficiency. The 3003 series also offers excellent heat-transfer properties and ensures uniform heating across the cookware body. 4. High Surface Quality Oil stains, scratches, dents, and other surface defects are strictly controlled during production. The Circles have a flat, smooth surface that is especially suitable for cookware finishing processes such as anodizing and coating. They can maintain a semi-mirror finish after bright dipping and anodizing. 5. Safe and Non-Toxic The products comply with food-contact material requirements and are odorless, non-toxic, and safe for end users. Cookware, including non-stick pans made from 3003 alloy, is hygienic and safe for food-related applications. 6. Strong Corrosion Resistance Aluminum alloy Circles provide excellent resistance to atmospheric and marine environments, resulting in long service life and low maintenance costs. The 3003 series is particularly well known for its superior corrosion resistance. 7. Environmentally Friendly and Recyclable Aluminum is 100% recyclable and supports green manufacturing practices. It can be recycled and reused repeatedly, making it ideal for circular-economy and sustainable manufacturing initiatives. 8. Clean Edges and Reduced Die Wear The products can be manufactured through precision punching or cutting processes, resulting in neat edges with minimal burrs. This makes them suitable for automated feeding and continuous stamping production. Good roundness and edge quality also help reduce die wear and improve manufacturing efficiency. Company Profile We are a modern enterprise integrating aluminum material research and development, production, sales, and technical services, with 30 years of manufacturing experience. Our workshops are equipped with fully automated punching lines, precision annealing furnaces, high-precision slitting equipment, and online inspection systems.
