This research studies the effect of a range of variables on the properties of A356 aluminum reinforced with silicon carbide particles after extrusion process. These variables are the ratio of liquid material and the percentage of particles. The percentage of carbide particles used was 10%, 15% and 20%. %. The composites were prepared by vortex method. Experimental results were compared with the simulation results which were obtained by finite element method and neural network method. The results of the tensile tests conducted at room temperature for reinforced alloys before forming and after forming showed that the increase in the weight of silicon carbide particles caused a decrease in the tensile stress and strain in the as cast state. The deformed composites followed the same behavior, but with marked improvement in the maximum tensile stress and yield stress of the composites which was formed at 585 degrees Celsius and the improvement was less in the case of composites that have been formed at 595 degrees Celsius.
