bending, bending phenomenon will occur, I would like to annealing treatment. Does the master know the annealing temperature and time?And the same direction in the rolling, more than 1.5 of the thickness of cracking is more serious; it is proposed to increase the bending angle of R, annealing may not be solved.Or on the bending line and calendering line to cross 45 degrees (comparison fee)5052, aluminum stamping bending will not break it.Please call 0379-68311128 for technical consulting division wangke.Other related question
