Title: Cylinder suitable for photosensitive drum or the like of electrophotographic copying machine
Inventor: TSUKUDA ICHIZO
IPC: C22C21/00
Filed: 1987-06-08
Abstract: PURPOSE:To prevent seizure at the time of color working after extrusion in a production stage and to enable formation at a high working rate by dispersing a hard boride uniformly into an aluminum alloy by addition and incorporation of a specified ratio of B thereto. CONSTITUTION:A cylinder is basically formed of the aluminum alloy contg. B in a 0.001-0.5wt.% range and consisting of the balance aluminum and unavoidable impurities. The hard intermetallic compd. (AlB2) with the aluminum is formed in an adequately dispersed state in the cylinder material. The boride exhibits an excellent cleaning effect on the bearing face of a die at the time of extrusion. Adhesion of the aluminum to the bearing face is thereby prevented and a uniform surface characteristic is formed over the entire circumference and length of the extruded pipe; the extrusion speed is eventually increased. The seizure in the ensuing cold working is prevented and the formation at the high working rate is enabled.
