Подробный технический паспорт: 1050 Алюминиевый круг

1. Material Definition & Стандарты

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. Основной химический состав & Металлургические характеристики

Its primary chemical composition is Aluminum (Ал) ≥ 99.5%, with strictly controlled impurities: Железо (Фе) ≤ 0.40%, Кремний (И) ≤ 0.25%, and other trace elements (Cu, Мин., мг, 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 & Электрическая проводимость: Second only to higher purity grades like 1060/1070, with a thermal conductivity of 222 ж/(м·К), making it ideal for heat transfer applications.
• Superior Anodizing Response: Homogeneous composition facilitates the formation of a uniform, плотный, and easily colorable anodic oxide layer.

3. Физический & Механические свойства

• Физические свойства: Плотность: 2.71 г/см³, Точка плавления: ~660°C, Электрическая проводимость: ~61% IACS.
• Механические свойства (Temper Dependent):
  • Темпер О (Отожженный): Низкий предел текучести, наибольшее удлинение (typically ≥ 30%), representing the optimal condition for deep drawing operations.
  • Temper H14 (полужесткий): Деформационно-упрочненный, 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:

• Производство посуды (Основное приложение): Leverages its высокая теплопроводностьи превосходная глубокая вытяжка​ for producing pot bodies, внутренние кастрюли скороварки, и внутренние кастрюли для рисоварки. After anodizing or coating with non-stick composites, it meets requirements for safety, долговечность, and cooking efficiency.
• Осветительные приборы & Отражатели: Benefits from its высокая отражательная способностьи 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, и ease of sheet metal fabrication, making it an ideal substrate for traffic signs and road plates.
• Электроника & Общее оборудование: Commonly used for heat sinks, capacitor cases, and other stamped parts requiring electrical/thermal conductivity or specific forming characteristics.

5. Selection Advantages & Сравнительный анализ

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:

• Размерные допуски: Допуск по толщине (например, ±0,05 мм), Допуск диаметра.
• Механические свойства: Удлинение​ is the key indicator for predicting deep drawability; O temper material should typically be ≥ 30%.
• Formability Indicators: Прибыльная стоимость; a lower value indicates less edge waviness after drawing, signifying lower material anisotropy.
• Микроструктура & Поверхность: Однородность размера зерна; surface must be free of scratches, отметки рулона, и масляные пятна.
• Применимые стандарты: АСТМ Б209, В 485-2, ГБ/Т 3880.1, и т. д..

7. Selection Guide Summary

The 1050 aluminum circle has established dominance in industries like cookware, освещение, and signage due to its unmatched deep drawability, отличная тепло/электрическая проводимость, superb surface treatment potential, and significant cost-effectiveness. For material selection:

• Для extreme deep drawing or spinning operations, Темпер О​ 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 алюминиевый круг, as a high-performance, fully recyclable engineering material, continues to have broad application prospects.
