Surface defect types of 5052 aluminum plate

Surface defect types of 5052 aluminum plate

5052 aluminum plate is an AL Mg alloy aluminum plate, and magnesium is the main alloying element in 5052 alloy aluminum plate. It is the most widely used anti rust aluminum. This alloy has high strength, especially fatigue resistance, high plasticity and corrosion resistance, and cannot be strengthened by heat treatment. It has good plasticity during semi cold work hardening, low plasticity during cold work hardening, good corrosion resistance, good weldability, poor machinability, and can be polished.

Surface defect types of 5052 aluminum plate:

1. Embossing:

The irregular color difference on the surface of the rolling rolls caused by wrinkling and breakage of the strip is periodically printed onto the surface of the strip during the rolling process.

2. Scratches:

Manifested as bundles of distributed scars on the surface of 5052 aluminum plate. Cause: Mechanical or manual movement between layers of 5052 aluminum plate.

3. Edge warping:

Due to the edge warping of the strip after rolling or shearing.

4. Corrosion:

Manifested as white or black spots in the form of dots or flakes on the surface of 5052 aluminum plate. Cause: During packaging, transportation, and storage, acid, alkali, or water may have entered.

5. Surface oil stains:

Manifested as dirt on the surface. Cause: Dirty cooling oil and insufficient blowing.

6. Scratches:

Manifested as scratches with line distribution on the surface of 5052 aluminum plate. Cause: The guide plate or flat rolling has protrusions or aluminum sticking; Scratches generated during the shearing process; Improper manual inspection and lifting. (Shanghai aluminum plate manufacturer)

7. Side bending:

The longitudinal side of the board or strip shows a non straight state of bending towards one side. Cause: The amount of compression at both ends of the rolling mill is different; Inconsistent thickness on both sides of the board and strip incoming materials.

8. Black spots on the surface:

There are needle shaped black spots on the surface of 5052 aluminum plate. Cause: The furnace liquid is not clean.
