Has anybody heard of bending sheet stock (.063 5052-H32 Aluminum)with grain direction on the diagonal? Local sheet metal shop (not an aircraft shop) experienced cracking on folding up a simple bracket. The bracket is like an upside down 6"long x 4"wide x 2"high box but has integral attaching flanges on the two 4" ends. I say with a zero bend radius (not 2-3t) and no concern for grain direction they were asking for cracks and failure even with this material. I have never ever heard of a spec calling for diagonal grain direction.
What say you??
