[Industrial Application Field] The present invention relates to an extruded aluminum alloy with excellent amorphous silicon vapor deposition properties, and more specifically, an extruded aluminum alloy with excellent amorphous silicon vapor deposition properties suitable for copying machine drums, laser printers, etc. Concerning extruded aluminum alloys. [Prior art] Generally, CdS is used as a photosensitive agent for copying machine drums.
However, these photosensitizers have low hardness and are not suitable for making large quantities of copies, and must be replaced every time a certain number of copies are made. BACKGROUND ART In recent years, amorphous silicon has been used as a photosensitive agent with excellent printing durability, heat resistance, and image quality in laser printers for computer output, drums of high-speed copying machines, and the like. This amorphous silicon is generally processed by cutting,
It is deposited on the surface of a base material that has been processed into a mirror-like state by polishing, surface treatment, etc. However, when printing with a drum, printer, etc. obtained in this manner, it has often been experienced that localized areas of poor image quality occur. The cause of this poor image quality is said to be due to the material itself, in addition to the amorphous silicon vapor deposition process (dirt, adhesion of particles, etc.), and there has been a strong desire to improve this material. In order to meet this conventional demand, as an aluminum alloy for amorphous silicon deposition,
Attempts have been made to use alloys such as AA3003, AA5086, and AA6063, but this AA5086 alloy has a low Mn content.
In addition to 0.2 to 0.7 wt%, it also contains impurities such as Fe and Si. These compounds form crystallized substances and interfere with the surface finish. ) etc. as the photosensitive agent cannot satisfy the required accuracy. [Problems to be Solved by the Invention] As a result of intensive research into the material-related causes of local image quality defects that occur during the deposition of amorphous silicon, which has been conventionally used as explained above, the present inventors have discovered the following: We found that this was caused by crystallized substances contained in the alloy, and based on this knowledge, we developed an extruded aluminum alloy with excellent vapor deposition properties for amorphous silicon. That is, as explained above, amorphous silicon is deposited on a substrate in the shape of a cylinder, flat plate, polyhedron, or other shape whose surface has been mirror-finished by cutting, polishing, or other means, and copying and printing are not possible. By irradiating this amorphous silicon with a beam of light such as a laser, it becomes partially electrically charged, toner for printing and printing is electrostatically attached to that area, and this is transferred to paper. However, in this case, if a crystallized substance different from the matrix exists on the uniform mirror-like surface, the charging characteristics of the amorphous silicon in that area will partially change, and the adhesion of toner for printing will be affected. It is presumed that this is not sufficient and therefore causes poor image quality. Conventional aluminum alloys contain relatively high concentrations of Fe and Si as impurities, as well as Mn and Cr to improve strength and other properties, but the amorphous silicon according to the present invention In extruded aluminum alloys with excellent vapor deposition properties, by suppressing the content of Mn, which is an impurity and a crystallized substance forming element, to a low content, and in particular, suppressing the Cr content to a low content, By extremely suppressing the formation of crystallized substances, localized image quality defects are prevented. [Means for Solving the Problems] The extruded aluminum alloy of the present invention, which has excellent vapor deposition characteristics for amorphous silicon, is characterized by containing 3.0 to 6.0 wt% of Mg, and 0.3 wt% of Mn as an impurity. % or less, Cr less than 0.01wt%, Fe 0.15wt% or less, Si 0.12wt% or less, and the remainder consists of Al. The extruded aluminum alloy having excellent amorphous silicon vapor deposition properties according to the present invention will be described in detail below. First, the components and component ratios of the extruded aluminum alloy having excellent amorphous silicon vapor deposition properties according to the present invention will be explained. Mg is an element that improves strength, and the content
If the content is less than 3.0wt%, it will be easily deformed during processing such as cutting and polishing, impairing image quality, and if the content exceeds 6.0wt%, hot workability will deteriorate. By the way, Mg
The content is 3.0 to 6.0wt%. Mn is contained as an impurity, and if the content exceeds 0.3 wt%, crystallized Al 6 (MnFe) is formed and the surface finish is impaired. Therefore, the Mn content is
It is necessary to suppress it to 0.3wt% or less. Like Mn, Cr is contained as an impurity, and if the content exceeds 0.01 wt%, crystallized Al 7 Cr is formed, causing poor image quality. Therefore, the Cr content is
Must be suppressed to less than 0.01wt%. Both Fe and Si are impurities like Mn and Cr.
Mn, Fe content is 0.15wt% and Si content is
If it exceeds 0.12wt%, Al-Fe or Al-Fe
- Forms Si-based crystallized substances, resulting in poor image quality.
In addition, when Fe is contained at the same time as Mn, Al 6
(MnFe) promotes the formation of crystallized substances, and if Si is contained at the same time as Mg, it will form Mg 2 Si crystallized substances, resulting in noticeable poor image quality, so special attention must be paid to the Fe and Si contents. Must be. Therefore, the Fe content is 0.15wt% or less, and the Si content is 0.12wt%.
It is necessary to suppress the following. In addition to the contained elements explained above, the content of Ti and B, which are usually used for grain refinement, is
If it is less than 0.04wt%, it will not deteriorate the properties, so this content is permissible.
Although it does not have a large effect on image quality, it impairs corrosion resistance, so it is desirable to keep it at 0.6 wt% or less. [Example] Next, an example of an extruded aluminum alloy having excellent amorphous silicon vapor deposition characteristics according to the present invention will be described. Example An aluminum alloy having the components and proportions shown in Table 1 was cast according to a conventional method to form an ingot of 200 mmφ, and this ingot was subjected to hot extrusion and extraction processing.
The tube was made with an outer diameter of 80 mmφ and a wall thickness of 3.5 mm (heated to H14). After rough cutting this tube, we use an ultra-precision lathe to improve the surface roughness.
Finished to Rmax=0.03~0.05μm, plasma-
Approximately 17μ of amorphous silicon is produced using the CVD method.
It was deposited and subjected to image quality evaluation. The image quality was evaluated by copying completely black using the normal black printing method and evaluating the degree of unevenness on the screen.
Image quality defects include dots and density unevenness, and those with no defects are A, those with dot defects or partial density unevenness are B, and those with overall density unevenness are C. And so. Table 2 shows the mechanical properties of the sample materials and the results of image quality evaluation. As is clear from Table 2, the aluminum alloy of the present invention, which has excellent amorphous silicon vapor deposition characteristics, has extremely excellent image quality and crystallization of Fe, Si, Mn, Cr, etc. It can be seen that images containing substance-forming elements often have poor image quality. Note that the larger the size of the crystallized particles, the more noticeable the image quality defects, so it is desirable to limit the maximum length of the crystallized particles to 15 μm or less.
