First claim
Opening claim text (preview).
The invention claimed is: 1. An aluminum alloy having a composition consisting of Si: 0.03 to 0.6 mass %, Fe: 0.1 to 0.7 mass %, Cu: 0.05 to 0.17 mass %, Mn: 1.06 to 1.20 mass %, Mg: 0.02 to 0.05 mass %, Zn: 0 to 0.02 mass %, Ti: 0.01 to 0.02 mass %, and the balance being Al and inevitable impurities. 2. A production method of an aluminum alloy extruded member, wherein an aluminum alloy billet having the composition as recited in claim 1 is extruded. 3. The production method of an aluminum alloy extruded member as recited in claim 2 , wherein the extruded member is an aluminum alloy extruded tube for a photoconductor drum substrate. 4. A production method of a photoconductor drum substrate, wherein an aluminum alloy extruded tube for a photoconductor drum substrate obtained by the production method of an aluminum alloy extruded member as recited in claim 3 is drawn. 5. A production method of a photoconductor drum substrate, wherein an aluminum alloy extruded tube for a photoconductor drum substrate obtained by the production method of an aluminum alloy extruded member as recited in claim 3 is ironed. 6. An aluminum alloy extruded member having a composition consisting of Si: 0.03 to 0.6 mass %, Fe: 0.1 to 0.7 mass %, Cu: 0.05 to 0.17 mass %, Mn: 1.06 to 1.2 mass %, Mg: 0.02 to 0.05 mass %, Zn: 0 to 0.02 mass %, Ti: 0.01 to 0.02 mass %, and the balance being Al and inevitable impurities. 7. The aluminum alloy extruded member as recited in claim 6 , wherein the extruded member is an aluminum alloy extruded tube for a photoconductor drum substrate. 8. A photoconductor drum substrate made of an aluminum alloy having a composition consisting of Si: 0.03 to 0.6 mass %, Fe: 0.1 to 0.7 mass %, Cu: 0.05 to 0.17 mass %, Mn: 1.06 to 1.2 mass %, Mg: 0.02 to 0.05 mass %, Zn: 0 to 0.02 mass %, Ti: 0.01 to 0.02 mass %, and the balance being Al and inevitable impurities.
