1. Small peeling: This kind of defect mostly occurs in the raw materials of the Cu-Fe-P series products. The second phase rich in Fe is often seen in the peeling place, which is very different from the basic characteristics. The whole process of cold rolling is due to its large deformation stress. caused. At the same time, serious scratches and scratches are also likely to cause stripes of peeling on the surface of the aluminum bronze plate.
2. Spot printing: This defect is due to the adhesion, pressing and drying treatment of cold-rolled materials to solve the technological process.
3. Eyes of needles: Scratches and gnawing of small particles of dirt during the production process of aluminum bronze plates will all cause the defects of eye of needles.
4. Cracks: The shrinkage mechanism and internal loosening of the aluminum bronze plate itself are easy to occur in the shape of cracks on the surface of the plate.
