Bone implants are a tool used as a support of body parts, and bone support in cases of fractures. Scaffold, plate, bone screw, and some other tools can be used in combination to support and fill the connection between broken bones before the tissue grows. The most commonly used implant materials are Titanium, Stainless steel and ceramics, which are very common in the use of medical devices. Biocompatible materials are taken into consideration when planning a medical device. This research intended to know the durability of duralumin material as the latest implant material, as the development and breakthrough in health world. The research methodology used in this study was the optimization in Ansys software 18.1. The implants were designed, the material strength was determined and then given imposition with 6 variations (450 N, 550 N, 650 N, 750 N, 850 N and 950 N). The optimization was a method that identified mat erial strength including Equivalent Stress, Shear Stress and Total Deformation of duralumin material as implant materials with loading variations. Based on the results of the research, the duralumin material had a equivalent stress of 475,700 Pa which was higher than 950000 Pa for ZnO-Al2O3 implants, while the duralumin shear stress of 1084500 Pa was higher than 313720 Pa for ZnO-Al2O3 implants. When compared with titanium implants, the highest equivalent stress of 150000 Pa duralumin material had a higher compression stress than titanium. The highest shear stress of titanium 4358.1 Pa means an implant with a higher shear duralumin material of titanium. Whereas if it was compared to stainless steel with voltage press 564000000 Pa, then the duralumin’s pressure was getting lower. Material hardness affects resistance to wear and tear. Duralumin material hardness was lower than Titanium and ZnO-Al2O3, so total Duralumin deformation (elasticity) was higher than Titanium and ZnO-Al2O3.
