Abstract
roll forming today are more prevalent in the part. Industrial electrical components Electronics industry Even the jewelry industry Forming Processes Is to make material changes shape permanently. The force from the outside, the more resistance. Changes in the shape, material In which the board will shrink each time property changes. The properties of the strain hardening of the material. To study the problems caused by the material properties of the passive force in forming
the project permanent deformation behavior in the process of forming a hollow tube for lead and tin. To search for labor in forming and the strain hardening. Determined by the thickness of the metal, lead and tin. The size and thickness of 2 mm, respectively 4,3.5,3,2.5 roll diameter and 12 mm to tensile testing. From the test results came out strong in the tin forming the board, the lighter. The strain hardening lead to a more powerful strain of tin, so forks suitable for forming
word: permanent deformation, the forming tube, stress - stress.
