[Prior Art] An aluminum alloy pipe used for an amorphous silicon photosensitive drum is required to have a surface roughness with an Rmax of 0.05 μm or less for the purpose of use. For this reason, aluminum alloy pipes are manufactured by mirror cutting by precision cutting with a natural diamond bite. It is also required that there is no scratch on the surface during cutting. Therefore, Al-Mg-based, Al-Mn-based, and Al-Si-based alloys are used as materials. In particular, aluminum ingots having a purity of 99.99 wt% or more are used for those requiring a strict surface finish.

Here, the reasons for limiting the added elements of the aluminum alloy will be described below. The reason why the total amount of aluminum and / or magnesium oxides is set to 0.002 wt% or less is that the cause of scratches that occur during precision cutting of aluminum alloys is caused by ingots or ingots from aluminum ingots or castings. Or produced in the molten metal, contained in the ingot
This is based on the fact that it was found through experiments that Al or Mg oxides were present in Al 2 O 3 , MgAl 2 O 4 , MgO and the like. Set the total amount to 0.
The reason for keeping 002 wt% or less is that Al or M
This is because the frequency of occurrence of scratches originating from the oxide of g is reduced. The means of controlling the total amount of aluminum and / or magnesium oxide to 0.002 wt% or less is to perform degassing with a degassing agent in a melting furnace, and perform bubbling with an inert gas in a refining furnace.
It can be obtained by measuring the amount of aluminum and / or magnesium oxide in the molten metal at the outlet of the filter through a tubular filter.

Next, the reasons for limiting the additive elements of the aluminum alloy will be described below.

Mg and Mn may be added to improve the strength of the aluminum alloy, either of them may be added, or both may be added together. If the Mg content is less than 0.05 wt%, there is no effect of improving the strength, and if the Mg content exceeds 5.5 wt%, the extrudability and corrosion resistance of the aluminum alloy will be impaired, so the Mg content is 0.
It was set to 05 to 5.5 wt%. If the Mn content is less than 0.05 wt%, there is no effect of improving the strength, and if it exceeds 1.5 wt%, the extrudability and corrosion resistance of the aluminum alloy will be impaired, so the Mn content was set to 0.05 to 1.5 wt%.

The reason for setting the Fe content to 0.35% by weight or less is that if the content exceeds 0.35% by weight, an Al—Fe crystallized substance is formed and the surface roughness and corrosion resistance deteriorate. The reason for setting the Si content to 0.20% or less is that if it exceeds 0.20%, a crystal of Mg 2 Si is formed and the surface roughness and corrosion resistance deteriorate. The reason why the content of Cr is set to 0.20 wt% or less is that if it exceeds 0.20%, the corrosion resistance deteriorates.
