This research is an aluminum, semi-solid casting technology SSM 356 Produced friction points. The speed of 380 1240 and 2500 rev / min to a depth of 1 and 1.5 mm, and its time to hit a dip of 30 and 60 found that physical appearance on the front surface of welds in all conditions of harmonization in the weld. And at the base of the weld penetration is good no cracks, no harmonization of the weld. Currently, treatment, and found that it can increase the hardness and tensile strength. The hardness of the workpiece by means of friction points with an average of approximately 63.90 HV hardness, which is higher than the original metal, representing 36.49% compared to the same metal. (Stiffness metal was approximately 40.58 HV) the condition for maximum hardness is the speed at 1240 rev / min to a depth of 1 mm, and its time to hit a dip of 60 seconds, the tensile strength of the workpiece. Processed Currently, an average of approximately 233.48 MPa and the condition that the tensile strength is the maximum speed of 380 rev / min to a depth of 1.5 mm, and its time to hit soak for 60 seconds, the study could be considered. Currently, the process can improve the mechanical properties of aluminum to semi-solid casting.
