Aluminum Plate Inspection Process
Document Verification
Check material certificates (e.g., EN 10204 3.1/3.2, ASTM B209).
Verify mill test reports (MTRs) for alloy grade, temper (e.g., 6061-T6), and standards compliance.
Visual Inspection
Surface defects: Cracks, scratches, dents, or discoloration.
Coating quality (if applicable): Evenness of anodized/painted layers.
Dimensional Check
Thickness, width, length (± tolerance per ASTM/ISO standards).
Flatness and edge straightness.
Material Testing
Hardness test: Rockwell/Vickers (e.g., HRB for soft alloys).
Tensile test: Yield/ultimate strength (per ASTM E8/E21).
Chemical composition: Spectrometer analysis for alloy elements (e.g., Si, Mg, Cu).
Non-Destructive Testing (NDT)
Ultrasonic testing: Internal voids/delamination.
Eddy current: Surface cracks (for conductive alloys).
Corrosion Inspection
Salt spray test (ASTM B117) for coated plates.
Pitting resistance check (if specified).
Packaging & Marking
Confirm protective packaging (anti-scratch film, moisture-proof).
Verify labels: Alloy, temper, batch no., and supplier details.
