Assumptions
Verify before production
These links use nominal material-specific gauge thicknesses and BendMath default forming assumptions. Confirm bend deduction, springback, tooling capacity, grain direction, and material condition with supplier data and a shop test bend.
Default K-factor, minimum-radius factor, and tonnage multiplier for 5052-H32 aluminum are starting estimates. See /reference/data-sources/ for provenance.
