Kapsamlı Teknik Veri Sayfası: 1050 Alüminyum Çember

1. Material Definition & Standartlar

The 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. Çekirdek Kimyasal Bileşimi & Metalurjik Özellikler

Its primary chemical composition is Aluminum (Al) ≥ 99.5%, with strictly controlled impurities: Ütü (Fe) ≤ 0.40%, Silikon (Ve) ≤ 0.25%, and other trace elements (Cu, MN, Mg, 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.
• Excellent Thermal & Elektriksel İletkenlik: Second only to higher purity grades like 1060/1070, with a thermal conductivity of 222 W/(m·K), making it ideal for heat transfer applications.
• Superior Anodizing Response: Homogeneous composition facilitates the formation of a uniform, yoğun, and easily colorable anodic oxide layer.

3. Fiziksel & Mekanik Özellikler

• Fiziksel Özellikler: Yoğunluk: 2.71 g/cm³, Erime Noktası: ~660°C, Elektriksel İletkenlik: ~61% IACS.
• Mekanik Özellikler (Temper Dependent):
  • Öfke O (Tavlanmış): Düşük akma dayanımı, en yüksek uzama (typically ≥ 30%), representing the optimal condition for deep drawing operations.
  • Temper H14 (Yarı Sert): Gerilmeyle sertleştirilmiş, 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:

• Tencere İmalatı (Birincil Başvuru): Leverages its yüksek termal iletkenlik​ ve üstün derin çekilebilirlik​ for producing pot bodies, düdüklü tencere iç tencereleri, ve pirinç ocağı iç tencereleri. After anodizing or coating with non-stick composites, it meets requirements for safety, dayanıklılık, and cooking efficiency.
• Aydınlatma & Reflektörler: Benefits from its yüksek yansıtma​ ve 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, Ve ease of sheet metal fabrication, making it an ideal substrate for traffic signs and road plates.
• Elektronik & Genel Donanım: Commonly used for heat sinks, capacitor cases, and other stamped parts requiring electrical/thermal conductivity or specific forming characteristics.

5. Selection Advantages & Karşılaştırmalı Analiz

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:

• Boyutsal Toleranslar: Kalınlık toleransı (E.G., ±0,05 mm), Çap toleransı.
• Mekanik Özellikler: Uzama​ is the key indicator for predicting deep drawability; O temper material should typically be ≥ 30%.
• Formability Indicators: Kazanç Değeri; a lower value indicates less edge waviness after drawing, signifying lower material anisotropy.
• Mikroyapı & Yüzey: Tane büyüklüğü tekdüzeliği; surface must be free of scratches, rulo işaretleri, ve yağ lekeleri.
• Geçerli Standartlar: ASTM B209, İÇİNDE 485-2, GB/T 3880.1, vesaire.

7. Selection Guide Summary

The 1050 aluminum circle has established dominance in industries like cookware, aydınlatma, and signage due to its unmatched deep drawability, mükemmel termal/elektrik iletkenliği, superb surface treatment potential, and significant cost-effectiveness. For material selection:

• İçin extreme deep drawing or spinning operations, Öfke O​ 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 alüminyum daire, as a high-performance, fully recyclable engineering material, continues to have broad application prospects.
