व्यापक तकनीकी डाटा शीट: 1050 एल्यूमिनियम सर्किल

1. Material Definition & मानकों

NS 1050 aluminum circle is a round blank manufactured by stamping or shearing from 1050 aluminum sheet or coil. This grade belongs to the 1xxx series of industrial pure aluminum as per standards like GB/T 3880, with a minimum aluminum content of 99.5%. Due to its high purity, this material exhibits exceptional plastic formability and excellent corrosion resistance, making it a primary choice for complex forming processes such as deep drawing and spinning.

2. कोर रासायनिक संरचना & धातुकर्म विशेषताएँ

Its primary chemical composition is Aluminum (अली) मैं 99.5%, with strictly controlled impurities: लोहा (फ़े) ≤ 0.40%, सिलिकॉन (और) ≤ 0.25%, and other trace elements (साथ में, एम.एन., मिलीग्राम, Zn each ≤ 0.05%). This high-purity composition results in the following metallurgical traits:

• High Plasticity: A pure crystalline structure with low resistance to dislocation movement allows for severe cold deformation without cracking.
• उत्कृष्ट थर्मल & इलेक्ट्रिकल कंडक्टीविटी: Second only to higher purity grades like 1060/1070, with a thermal conductivity of 222 डब्ल्यू/(एम·के), making it ideal for heat transfer applications.
• Superior Anodizing Response: Homogeneous composition facilitates the formation of a uniform, घना, and easily colorable anodic oxide layer.

3. भौतिक & यांत्रिक विशेषताएं

• भौतिक गुण: घनत्व: 2.71 जी/सेमी³, गलनांक: ~660°C, इलेक्ट्रिकल कंडक्टीविटी: ~61% IACS.
• यांत्रिक विशेषताएं (Temper Dependent):
  • टेम्पर ओ (annealed): कम उपज शक्ति, उच्चतम बढ़ाव (typically ≥ 30%), representing the optimal condition for deep drawing operations.
  • Temper H14 (आधा कठोर): तनाव से कठोर, offering higher strength (Tensile Strength ~100-130 MPa) and moderate formability, suitable for shallow-formed parts requiring some rigidity.

4. Analysis of Primary Application Fields

Its applications are logically derived from its core properties:

• कुकवेयर विनिर्माण (प्राथमिक अनुप्रयोग): Leverages its उच्च तापीय चालकता​ और बेहतर गहरी निकासी क्षमता​ for producing pot bodies, प्रेशर कुकर भीतरी बर्तन, और चावल कुकर के भीतरी बर्तन. After anodizing or coating with non-stick composites, it meets requirements for safety, टिकाऊपन, and cooking efficiency.
• प्रकाश & रिफ्लेक्टर: Benefits from its उच्च परावर्तन​ और excellent anodizing response, making it widely used for LED lamp covers, reflector housings, and luminaire shells. Surface treatment can achieve reflectivity over 80%.
• Traffic Signs & Plates: Utilizes its good atmospheric corrosion resistance, adequate strength, तथा ease of sheet metal fabrication, making it an ideal substrate for traffic signs and road plates.
• इलेक्ट्रानिक्स & सामान्य हार्डवेयर: Commonly used for heat sinks, capacitor cases, and other stamped parts requiring electrical/thermal conductivity or specific forming characteristics.

5. Selection Advantages & तुलनात्मक विश्लेषण

Compared to other common aluminum circle grades, 1050 offers the best balance between performance and cost:

6. Key Quality Control Parameters

Professional procurement and incoming inspection should focus on:

• आयामी सहनशीलता: मोटाई सहनशीलता (जैसे, ±0.05मिमी), व्यास सहनशीलता.
• यांत्रिक विशेषताएं: बढ़ाव​ is the key indicator for predicting deep drawability; O temper material should typically be ≥ 30%.
• Formability Indicators: बाली का मूल्य; a lower value indicates less edge waviness after drawing, signifying lower material anisotropy.
• सूक्ष्म & सतह: अनाज के आकार की एकरूपता; surface must be free of scratches, रोल के निशान, और तेल के दाग.
• लागू मानक: एएसटीएम बी209, पर 485-2, जीबी/टी 3880.1, आदि.

7. Selection Guide Summary

NS 1050 aluminum circle has established dominance in industries like cookware, प्रकाश, and signage due to its unmatched deep drawability, उत्कृष्ट तापीय/विद्युत चालकता, superb surface treatment potential, and significant cost-effectiveness. For material selection:

• के लिए extreme deep drawing or spinning operations, टेम्पर ओ​ 1050 aluminum circle is the primary choice.
• For parts requiring some structural rigidity​ with shallow forming, Temper H14 or H24​ can be selected.
• For cookware requiring high-temperature brazing, its melting point limitation must be considered, ensuring compatibility with coatings or composite bases.

Amidst trends towards lightweight manufacturing and the green circular economy, 1050 एल्यूमीनियम सर्कल, as a high-performance, fully recyclable engineering material, continues to have broad application prospects.
