1060 हॉट रोल्ड एल्यूमिनियम सर्कल: बुनियादी बातों से लेकर उच्च-मूल्य वाले अनुप्रयोगों तक की संपूर्ण मार्गदर्शिका

In the cookware, प्रकाश, and general manufacturing industries, NS 1060 हॉट रोल्ड एल्यूमिनियम सर्कल​ plays a vital role. This circular blank, made from high-purity aluminum via hot rolling, is an ideal choice for deep drawing, कताई, and similar processes due to its exceptional formability, ऊष्मीय चालकता, और लागत-प्रभावशीलता. This article provides a comprehensive analysis of its material properties, process advantages, specification systems, and innovative applications, offering in-depth insight for your material selection and procurement.

1. Core Analysis: The Dual Advantages of 1060 Alloy and Hot Rolling

NS 1060 गरम वेल्लित एल्यूमिनियम सर्किल​ is a circular sheet produced by hot rolling 1060 एल्यूमीनियम मिश्र धातु (Al content ≥99.6%) into strip, followed by precision cutting or blanking. Its core value stems from the perfect combination of “सामग्री” तथा “प्रक्रिया”:

• Material Core (1060 एल्यूमीनियम मिश्र धातु): A commercially pure aluminum grade with excellent electrical conductivity (≥61% आईएसीएस), ऊष्मीय चालकता (~230 W/(एम·के)), and ductility, albeit with relatively lower strength. Its simple chemistry (containing minor amounts of iron and silicon) ensures excellent corrosion resistance and processing stability.
• Process Core (हॉट रोलिंग): The ingot is rolled above its recrystallization temperature (typically 300-500°C). This process eliminates casting defects, refines the grain structure, and increases material density. This grants the aluminum circle a more uniform internal structure, बेहतर गहरी निकासी क्षमता (higher Limiting Drawing Ratio), and better fatigue resistance, making it especially suitable for subsequent complex plastic deformation.

Compared to cold-rolled circles, 1060 hot-rolled circles in tempers like H14 or annealed (हे स्वभाव!) are significantly less prone to cracking, शिकन, या “बाली” during deep drawing or spinning, leading to a markedly higher production yield.

2. Detailed Performance Parameters and Technical Specifications

2.1 मुख्य निष्पादन संकेतक

2.2 Standard Specification Ranges

• व्यास: Common range from 50mm to 1600mm. Non-standard sizes are available per die specifications.
• मोटाई: Typically 0.5mm to 10.0mm. The cookware industry commonly uses 0.6mm-3.0mm.
• मनोवृत्ति:
  • हे (annealed): Softest temper, highest elongation, optimal for deep drawing, suitable for complex, deep-drawn shapes.
  • H12/H14/H16 (तनाव से कठोर): Different hardness levels achieved after cold rolling. H14 offers a good balance between formability and rigidity, making it the most widely used.
  • एच18 (पूरी मेहनत): High hardness, poor formability, typically used for simple bending or non-formed components.

2.3 Surface Quality and Tolerance Standards

• सतह: Should be clean, तेल के दाग से मुक्त, obvious rolling lines, स्क्रैच, or corrosion spots. High-end applications may require an “oil-free bright” खत्म करना.
• सहनशीलता: Precision stamping demands strict thickness (जैसे, ±0.05मिमी) और व्यास (जैसे, ±0.1मिमी) सहिष्णुता, which directly impact die life and product consistency.

3. मुख्य लाभ: क्यों चुनें? 1060 हॉट रोल्ड एल्यूमिनियम सर्कल?

1. Superior Deep Drawability and Spinnability: The high-purity aluminum base combined with the uniform plasticity from hot rolling allows for significant deformation in products like pots and lamp shades, outperforming many other alloys.
2. उच्च तापीय चालकता: Ensures rapid and even heat distribution in cookware, saving energy and promoting uniform cooking.
3. Excellent Corrosion Resistance and Hygiene: The stable surface oxide film prevents rusting and leaching of toxic substances, complying with food contact standards (जैसे, जीबी 4806.9).
4. Excellent Adaptability for Surface Treatment: Easily polished, ब्रश, एनोड किए गए, painted, or coated with non-stick materials (जैसे, टेफ़लोन), meeting diverse aesthetic and functional needs.
5. High Cost-Effectiveness and Recyclability: Relatively low material cost, साथ 100% recyclability of scrap, aligning with green manufacturing principles.

4. Mainstream and Emerging Application Fields

5. Key Points for Selection, खरीद, and Quality Control

1. Define Application Needs: Is it for deep drawing, कताई, or simple cutting? Is subsequent anodizing required? Determine the मनोवृत्ति (prefer O or H14)​ और surface requirements​ based on the final process.
2. Verify Key Certificates: Require the supplier to provide a सामग्री परीक्षण प्रमाणपत्र (एमटीसी)​ ensuring chemical composition meets standards like GB/T 3190. For food contact, ए food-grade compliance statement or test report​ आवश्यक है.
3. On-site Quality Checks:
   • DIMENSIONS & सहिष्णुता: Sample inspection using calipers and micrometers.
   • सतही गुणवत्ता: Visual inspection for defects. Check for residual oil with oil inspection paper if necessary.
   • Simple Formability Test: Request a trial die test from the supplier or conduct an “एरिचसेन कपिंग परीक्षण” to evaluate deep draw potential.
4. आपूर्तिकर्ता मूल्यांकन: Prioritize manufacturers with a stable supply of hot-rolled stock, precision slitting and circle shearing equipment, and the capability to provide technical support.

6. Market Trends and Future Development

1. Premiumization and Specialization: As cookware quality demands increase, so do requirements for the aluminum circle’s thickness uniformity and microstructural homogeneity (no coarse grains)​ to ensure non-stick coating longevity and product aesthetics.
2. Combining Large Size with Higher Strength: To meet the demand for one-piece forming of large lampshades and industrial parts, the stable production of large-diameter circles with moderately increased strength (जैसे, का उपयोग करते हुए 1100 या 3003 मिश्र धातु)​ is a growing trend.
3. Green and Sustainable: का उपयोग करते हुए 1060 billets with a high percentage of recycled aluminum to produce circles reduces the carbon footprint while maintaining performance, meeting global ESG demands.
4. Digitalization and Customization: Tracking production batches via IoT and combining this with customer die data to provide predictive forming process parameters shifts the value proposition from “selling material” प्रति “providing solutions.”
