Uitgebreid technisch gegevensblad: 1050 Aluminium cirkel

1. Material Definition & Normen

De 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. Kern chemische samenstelling & Metallurgische kenmerken

Its primary chemical composition is Aluminum (Al) ≥ 99.5%, with strictly controlled impurities: Ijzer (Fe) ≤ 0.40%, Silicium (En) ≤ 0.25%, and other trace elements (Cu, Mn, mgr, 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.
• Uitstekende thermische & Elektrische geleidbaarheid: Second only to higher purity grades like 1060/1070, with a thermal conductivity of 222 met(m·K), making it ideal for heat transfer applications.
• Superior Anodizing Response: Homogeneous composition facilitates the formation of a uniform, gespannen, and easily colorable anodic oxide layer.

3. Fysiek & Mechanische eigenschappen

• Fysieke eigenschappen: Dikte: 2.71 g/cm³, Smeltpunt: ~660°C, Elektrische geleidbaarheid: ~61% IACS.
• Mechanische eigenschappen (Temper Dependent):
  • Temperament O (Gegloeid): Lage vloeigrens, hoogste rek (typically ≥ 30%), representing the optimal condition for deep drawing operations.
  • Temper H14 (Half moeilijk): Gehard, 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:

• Productie van kookgerei (Primaire toepassing): Leverages its hoge thermische geleidbaarheiden superieure diepe trekbaarheid​ for producing pot bodies, binnenpotten voor snelkookpannen, en binnenpotten voor rijstkokers. After anodizing or coating with non-stick composites, it meets requirements for safety, duurzaamheid, and cooking efficiency.
• Verlichting & Reflectoren: Benefits from its hoge reflectiviteiten 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, En ease of sheet metal fabrication, making it an ideal substrate for traffic signs and road plates.
• Elektronica & Algemene hardware: Commonly used for heat sinks, capacitor cases, and other stamped parts requiring electrical/thermal conductivity or specific forming characteristics.

5. Selection Advantages & Vergelijkende analyse

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:

• Dimensionale toleranties: Dikte tolerantie (bijv., ±0,05 mm), Diametertolerantie.
• Mechanische eigenschappen: Verlenging​ is the key indicator for predicting deep drawability; O temper material should typically be ≥ 30%.
• Formability Indicators: Earingwaarde; a lower value indicates less edge waviness after drawing, signifying lower material anisotropy.
• Microstructuur & Oppervlak: Uniformiteit van de korrelgrootte; surface must be free of scratches, rolmarkeringen, en olievlekken.
• Toepasselijke normen: ASTM B209, IN 485-2, GB/T 3880.1, enz.

7. Selection Guide Summary

De 1050 aluminum circle has established dominance in industries like cookware, verlichting, and signage due to its unmatched deep drawability, uitstekende thermische/elektrische geleidbaarheid, superb surface treatment potential, and significant cost-effectiveness. For material selection:

• Voor extreme deep drawing or spinning operations, Temperament 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 aluminium cirkel, as a high-performance, fully recyclable engineering material, continues to have broad application prospects.
