### results for this questionWhat is k factor bend allowance?What is k factor bend allowance?To calculate bend allowance,the K-factor is multiplied by the thickness of the material; that number is then added to the bend radius.This number is multiplied by the angle of the bend times pi over 180.The formula is bend allowance = (K-factor x thickness +radius) x angle x (pi/180).What Is Bend Allowance? (with picture) - wiseGEEK results for this questionFeedbackBend Allowance Calculator JMTUSA

Bend allowance is the amount of metal to be added to the total layout.The most important considerations when bending metal is the min.bend radius.When bends are made smaller than the required min.radius,metal will crack at the outside heel of the bend.The min.radius of a bend is determined by the hardness and thickness of the metal.
