Design process of any product can consist of examining a design need and working on the problem by means of sketches, brain-storming, models, calculations as necessary, development of styling as appropriate and calculation of the costs. In this paper, the main aim is to design a supporting bracket of a pipe with a good style, a reliable factor of safety and low material cost. Four different materials were used to find out the minimum mass and cost of each model. NX8.5 Nastran was used for sketching and modeling. Moreover, a static simulation was done by the same software where a specific compressive load was applied as well as constraints to analyze stresses on the bracket. The load was estimated according to the pipe span. The result showed that the Steel alloy AISI4340 had the highest safety factor value of the design with Low material cost. Therefore, it was the best material of the design. Material cost of the model made of cast iron G60, Aluminum2014, and Steel AISI4340 were approximately the same despite the different required masses. The copper-c10100 was the most expensive with a low value of safety factor.
