PROFILE DEVELOPMENT / 6A
6A 3X13
6A 3X13: Flat sample record. This case uses material designation 6A and catalog dimensions 3 × 13 mm. Width-thickness ratio expression must retain both directional dimensions.
Geometric Focus Points
Thickness, width, edge fillets, and width-to-thickness ratio

Cross-sectional features and review points
This case is a flat-shaped sample identified as material grade 6A, with catalog dimensions 3 × 13 mm. The width-to-thickness ratio must retain both dimensional directions.
Drawings and measurement requirements
During review, list thickness and width tolerances, edge transitions, and cross-sectional orientation separately; straightness and twist shall be inspected per the agreed length reference.
Delivery and subsequent processing
If downstream processes require oriented feeding or bending, specify placement orientation, clamping zones, and delivery form—do not reverse-engineer process suitability from sample photographs.
Documentation basis and scope of confirmation
Data originates from this case’s catalog and internal sample photographs; catalog dimensions are nominal values, and photographs do not substitute formal inspection reports. Material standards, mechanical properties, heat treatment, supply conditions, and acceptance criteria must be confirmed per project.

Development Q&A
Can 3 × 13 and 3.5 × 10 be treated as the same cross-section?
No. The two catalog dimensions differ and must undergo separate review of target drawings, width-thickness requirements, and subsequent processing conditions.
What must be clarified for the longitudinal direction of wide-flat cross-sections?
Straightness, twist, bending direction, and measurement length must be specified per project and recorded separately from cross-sectional width/thickness requirements.
