What should I consider when purchasing aluminum round plates?
In industrial manufacturing, precision machining, or deep-processing, selecting the right aluminum round plates is crucial for ensuring product quality and process stability. The following are key technical considerations during the procurement process:
1. Clarify the end-use application and processing requirements.
Different applications have different requirements for the physical properties, dimensional accuracy, and surface quality of aluminum round plates:
- For deep drawing or spinning: Prioritize alloys with excellent ductility, such as 1100-O and 3003-H14.
- For structural and machined parts: Choose alloys with high strength and stability, such as 6061-T6/T651.
- For decorative applications: Surface treatment and corrosion resistance are more important, and anodizing or brushing is recommended.
2. Alloy Grade Selection Criteria
- 1100 Series: Pure aluminum with strong conductivity and corrosion resistance, suitable for deep drawing and lightweight structural parts.
- 3003 Series: With the addition of manganese, the strength is slightly higher than 1100, and it combines good ductility and corrosion resistance, making it suitable for kitchenware, lamp chassis, pressure vessels, etc.
- 6061 Series: A typical heat-treatable alloy, offering high strength, good weldability, and corrosion resistance, making it suitable for load-bearing structures and precision machining.
3. Heat Treatment Condition (Temper) Selection
The strength, workability, and residual stress control of aluminum round plates are closely related to their heat treatment condition:
- O Temper (Annealed Temper): Soft, suitable for high-deformation spinning and deep drawing.
- H14/H24: Medium strength, suitable for some plastic working.
- T6/T651: Artificially aged, providing higher strength and dimensional stability, suitable for structural parts and precision machining.
4. Dimensional Specifications and Processing Tolerances
Confirm the required outer diameter (OD), thickness, and flatness requirements, and discuss these with the supplier:
- Is fine grinding, leveling, or deburring required?
- Does the tolerance meet standards such as ASTM B209 and EN 485?
- Is custom-made molds or custom molds supported?
5. Surface Treatment and Cleanliness Level
Consider the need for surface treatment based on the intended use:
- Anodizing: Improves corrosion resistance and surface hardness;
- Brushed/mirror polish: Used for decorative purposes, lighting, kitchen appliances, etc.;
- Laminating or painting: Enhances scratch resistance and is suitable for products with high aesthetic requirements.
6. Stock Availability and Customization Capabilities
For large-volume or non-standard specifications, we recommend prioritizing the following information:
- Availability of standard diameters (e.g., ∅100mm–∅1000mm) and thicknesses (0.5–6mm);
- Whether the supplier has mold development, batch cutting, and secondary processing capabilities;
- Whether third-party quality inspection reports (e.g., SGS, BV) and material certification (MTC) are available.
