bending, bending phenomenon will occur, I would like to annealing treatment. Does the master know the annealing temperature and time?
Please call 0379-68311128 for technical consulting division wangke.
5052, aluminum stamping bending will not break it.
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)
