AC600 Aluminium AC600 Aluminium Roachman (Automotive) (OP) 17 Jan 15 06:17 Anyone out there able to furnish me with the ultimate tensile and shear stress of AC600 aluminium used in modern car bodies? Thanks in anticipation. RE: AC600 Aluminium TVP (Materials) 4 Feb 15 19:25 For exact values, you will need to contact Novelis, the provider of Anticorodal®-600 PX (AC-600). The typical treatment is to form the sheet in the T4 condition and then allow it to artificially age during a paint bake operation to a T6 or T8 condition. Typical values for tensile yield strength is ~ 200 MPa after aging, tensile ultimate strength ~ 240 MPa, and elongation of 10-12%. Shear ultimate strength is ~ 60% of tensile ultimate.
