Jinan, China – Jinan Zhongfu Aluminum Co., Ltd.'s 1/3 series aluminum discs have been widely recognized in global markets such as kitchen utensils, electronic components, and industrial packaging. As high-precision stamping and spinning materials, 1/3 series aluminum discs are favored for their uniform thickness, smooth surface, and excellent forming performance, serving as core materials in various deep processing fields.
Ⅰ Core Advantages of 1/3 Series Aluminum Discs
1/3 series aluminum discs have distinct characteristics to adapt to different precision processing needs:
1 Series (Pure Aluminum Discs): Feature high purity (Al ≥99.6%), excellent ductility and deep drawing performance, non-toxic and tasteless. They are compliant with food-grade standards, making them ideal for kitchen utensils, food packaging containers, and electronic component substrates that require good conductivity.
3 Series (Al-Mn Alloy Discs): Possess outstanding anti-rust performance and moderate strength, good wear resistance and stamping stability. Not easy to crack or deform during processing, they are suitable for industrial container covers, automotive interior trim parts, and chemical equipment accessories in humid environments.
Ⅱ Reasons for Choosing Zhongfu Aluminum 1/3 Series Aluminum Discs
1. High-Quality Raw Materials & Strict Quality Control
Our 1/3 series aluminum discs are made of high-purity aluminum ingots and imported manganese ingots (for 3 series), with strict control of chemical composition and impurity content to ensure material uniformity. The thickness tolerance is controlled within ±0.02mm, the surface is free of burrs, scratches and oil stains, and the flatness is high. All products undergo mechanical property testing, corrosion resistance testing (salt spray test ≥1000 hours for 3 series), and precision dimension inspection, with a qualified rate of 99.9%. All batches comply with international standards such as ASTM and GB/T.
2. Customized Solutions for Precision Processing
For kitchen utensil manufacturing, we provide 1 series food-grade aluminum discs with diameter φ100-600mm and thickness 0.8-3.0mm; for industrial container covers, we offer 3 series anti-rust aluminum discs with diameter φ150-800mm and thickness 1.5-5.0mm; for electronic components, we provide 1 series aluminum discs with precision cutting and deburring treatment. Common specifications: diameter φ50-1200mm, thickness 0.3-8.0mm, supporting non-standard customization of diameter, thickness, and surface treatment (passivation, polishing, etc.).
3. Professional Technical Support for Stamping
Our technical team with more than 10 years of aluminum processing experience provides one-stop services for stamping and spinning scenarios, including material selection guidance based on processing requirements, stamping parameter matching, and surface treatment scheme customization. We have helped 800+ customers in kitchenware, automotive, and electronic industries solve precision processing and performance matching problems.
4. Strong Production Capacity & Reliable Supply Chain
The annual production capacity of 1/3 series aluminum discs reaches 150,000 tons, with sufficient inventory of common specifications to meet large-order needs. We adopt anti-scratch film pasting and wooden pallet packaging to ensure product integrity during transportation. We cooperate with major ports to provide flexible international logistics solutions (sea, air, land transport) and complete customs clearance documents (certificate of origin, material test report), with an on-time delivery rate of 99.6%.
5. Factory-Direct Pricing & Global Recognition
We eliminate intermediate agents, helping customers save 10-18% of procurement costs. Our aluminum discs are exported to Europe, North America, Southeast Asia, and other regions, serving 250+ distributors and 4,200+ end customers. We hold ISO9001 and SGS certifications, with a customer repurchase rate of 92%.
