Our quality control process focuses on:
- Alloy composition verification
- Thickness consistency
- Diameter and roundness inspection
- Surface cleanliness and rolling condition
- Edge burr control
- Temper stability for forming operations
- Packaging inspection before container loading
For customers with strict forming requirements, we can discuss the intended drawing depth, spinning process, tooling condition, final use, and required mechanical properties before production. This helps us recommend a more suitable alloy and temper rather than supplying avgeneric aluminum circle.
