Aluminum plate it is widely used in our lives, the use of decoration projects, home decoration, communication electronic devices and other places is very common, but for aluminum plate there are still many people are not very clear, the following is to introduce to you: What are the common sense points in the use of aluminum plate?

1. Cut slots for aluminum plates

When cutting slots with a slotting machine or a gong machine, a semicircular turning tool should be used. Regardless of whether the damage to the aluminum plate is too deep, it is not shallow, not easy to expand, 0.2-0.3mm thick plastic core should be bent together with the aluminum plate to promote compressive strength and ductility, otherwise the aluminum plate is probably cut or the paint layer is split when bending.

2. Aluminum plate batch number

The same kind of aluminum plate with different batch numbers is likely to have color difference, and the color difference comparison procedure should be promoted when the printing paper with different batch numbers is sold and applied in the market. Enterprises key operation aluminum alloy aluminum plate, aluminum markings steel plate and so on. It can only be applied on the same plan if there is no color difference in the visual result.

3. Aluminum plate storage and handling

Aluminum plate should be stored in a dry and ventilated place, and flat on the surface, do not step on, impact, when transporting aluminum plate, the four sides of the plate should be lifted at the same time, so as not to scratch the surface of the plate.

4. Aluminum plate installation direction

When the same color aluminum plate is installed on the same plane, the flow direction should be consistent, otherwise it will produce visual color difference.

5. Aluminum plate conditions

Indoor wall panels should be used indoors and should not be installed outdoors to ensure the use effect and service life of aluminum panels.

6. Tear the film of aluminum plate

Remove the protective film within 45 days after the installation of the aluminum plate, otherwise it is difficult to remove the film or glue transfer occurs.

7. The aluminum plate is bent

When bending the edge, the ground stress is uniform, the shape is once, and it is not necessary to bend continuously, otherwise the aluminum plate is probably broken.

8. Arc production and processing of aluminum plate

Special bending machine should be used to carry out production and processing of the arc, so that the board can gradually achieve the required appearance, not a bend.

What is the effect of cold deformation on aluminum and aluminum plates?

Aluminum plate I believe we all know, it is also very common in our lives, such as mobile phone shell materials, car wheels, pull rod boxes, 3C products and other industry applications are very extensive, then you know the impact of cold deformation on aluminum and aluminum plate is what? Today I would like to introduce to you:

1. Texture and anisotropy

After large cold deformation of aluminum and aluminum sheet, the material shows anisotropy due to the texture. For example, aluminum sheet is prone to obvious lugging during deep drawing. The processing conditions should be reasonably controlled and the favorable aspects of texture and anisotropy should be fully utilized, and the unfavorable aspects should be avoided or eliminated.

Second, physical and chemical properties

1. Chemical stability

After cold deformation, the internal energy of the material increases, making its chemical properties more unstable, and easy to be corroded, especially easy to produce stress rot.

2. Density

After cold deformation, the density of aluminum decreases due to microcracks, macrocracks and holes in the crystals and intercrystals.

Step 3: Resistance

The destruction of intergranular material leads to direct grain contact, grain orientation ordering, intergranular and intra granular cracking, etc., which have obvious influence on the change of resistance. The first two make the TLDS decrease with the increase of the degree of deformation, while the latter is the opposite.

3. Chemical properties

After the cold deformation of aluminum and aluminum plate, due to the occurrence of intragranular and intergranular damage, lattice distortion and the appearance of the second type of residual stress, the plastic index drops sharply, and may be close to the complete brittle state in the limit state. In addition, due to lattice distortion, dislocation increase, grain elongation and refinement and the appearance of substructure, its strength index is greatly improved, that is, work hardening phenomenon.

What is the effect of cold deformation on aluminum and aluminum plates? Through the above introduction I believe you have also understood in detail, I hope the above sharing can help you.
