Aluminum to Aluminum T-Peel Bonds

The following data shows typical values obtained with the Scotch-Weld AF 126/Scotch-Weld EC-2320 system.

T-Peel specimens consist of two 8" x 12" x 0.020" (203 mm x 305 mm x 0.508 mm) sheets of 2024-T3 clad

aluminum bonded to each other from which 1" (25.4 mm) wide strips are cut for testing. Jaw separation rate was

3"/minute (75 mm/minute) during testing.
