Title: Aluminum alloy tube for bulge
Inventor: SAKOTA SHOICHI
IPC: C22C21/00
Filed: 1992-05-22
Abstract: PURPOSE:To prevent the occurrence of thickness deviation and cracking at the time of bulging by regulating the surface roughness of an Al alloy tube containing specific amounts of Mn and copper to a specific value or less.
