K Factor Sheet Metal - Sheet metal thickness t = 1mm bend angle a = 90° bend radius r = 1mm bend allowance factor ba = 2.1mm. Web based on the given information: Mathematically k factor value is equal to the ratio of position of the neutral. When metal is bent the top section is going to undergo compression.
