Abstract
Process routes for 5000 series aluminum alloy sheet produced with TBC(twin-belt casting) have been
successfully trialed, and applicability for inner structural parts of automobile was studied. The TBC 5000 sheet has finer microstructure than conventional DC processed 5000 series aluminum alloy sheet, resulting from the process characteristics. Optimization of composition and fine microstructure results in superior formability to DC5182 sheets. Moreover, the TBC 5000 sheet shows good performance in SCC resistance , adhesive bonding and coating tests, showing the ability for the application to hood-frame of car.
