Title:
ALUMINUM ALLOY AND METHOD FOR MANUFACTURING ALUMINUM ALLOY EXTRUDED MATERIAL
Document Type and Number:
WIPO Patent Application WO/2020/179307
Kind Code:
A1
Abstract:
Provided are an aluminum alloy whereby an outer surface having high smoothness can be formed, and manufacturing cost can be suppressed, a method for manufacturing an aluminum alloy extruded material, a method for manufacturing a photosensitive drum base, and an aluminum alloy extruded material and a photosensitive drum base. In the present invention, an aluminum alloy extruded material is manufactured by extruding an aluminum alloy billet 1 having a composition containing 0.060-0.080 mass% Si, 0.10-0.70 mass% Fe, 0.050-0.20 mass% Cu, and 1.0-1.5 mass% Mn, the remainder comprising Al and unavoidable impurities. This photosensitive drum base is manufactured by drawing or ironing a manufactured aluminum alloy extruded pipe for a photosensitive drum base.
