종합 기술 데이터 시트: 1050 알루미늄 원형

1. Material Definition & 표준

그만큼 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. 핵심 화학 성분 & 야금학적 특성

Its primary chemical composition is Aluminum (알) ≥ 99.5%, with strictly controlled impurities: 철 (철) ≤ 0.40%, 규소 (그리고) ≤ 0.25%, and other trace elements (구리, 망, 마그네슘, 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.
• 우수한 열 & 전기 전도도: Second only to higher purity grades like 1060/1070, with a thermal conductivity of 222 승/(m·K), making it ideal for heat transfer applications.
• Superior Anodizing Response: Homogeneous composition facilitates the formation of a uniform, 밀집한, and easily colorable anodic oxide layer.

3. 물리적 & 기계적 성질

• 물리적 특성: 밀도: 2.71 g/cm3, 녹는점: ~660°C, 전기 전도도: ~61% IACS.
• 기계적 성질 (Temper Dependent):
  • 성미 O (단련): 낮은 항복 강도, 최고 신장 (typically ≥ 30%), representing the optimal condition for deep drawing operations.
  • Temper H14 (하프 하드): 변형 경화, 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:

• 조리기구 제조 (기본 애플리케이션): Leverages its 높은 열전도율​ 그리고 우수한 딥드로잉성​ for producing pot bodies, 압력솥 내솥, 그리고 밥솥 내솥. After anodizing or coating with non-stick composites, it meets requirements for safety, 내구성, and cooking efficiency.
• 조명 & 반사경: Benefits from its 높은 반사율​ 그리고 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, 그리고 ease of sheet metal fabrication, making it an ideal substrate for traffic signs and road plates.
• 전자제품 & 일반 하드웨어: Commonly used for heat sinks, capacitor cases, and other stamped parts requiring electrical/thermal conductivity or specific forming characteristics.

5. Selection Advantages & Comparative Analysis

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:

• 치수 공차: 두께 공차 (예를 들어, ±0.05mm), 직경 공차.
• 기계적 성질: 연장​ is the key indicator for predicting deep drawability; O temper material should typically be ≥ 30%.
• Formability Indicators: 이어링 가치; a lower value indicates less edge waviness after drawing, signifying lower material anisotropy.
• 미세구조 & 표면: 입자 크기 균일성; surface must be free of scratches, 롤 마크, 그리고 기름 얼룩.
• 적용 가능한 표준: ASTM B209, 안에 485-2, GB/T 3880.1, 등.

7. Selection Guide Summary

그만큼 1050 aluminum circle has established dominance in industries like cookware, 조명, and signage due to its unmatched deep drawability, 우수한 열/전기 전도성, superb surface treatment potential, and significant cost-effectiveness. For material selection:

• 을 위한 extreme deep drawing or spinning operations, 성미 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 알루미늄 서클, as a high-performance, fully recyclable engineering material, continues to have broad application prospects.
