Present paper deals with a fine powder of tungsten (W) and nickel (Ni) reinforced epoxy (SikadurR-52) in different weight percentage (0%, 2%, 5%). Mechanical tests consist of tensile; flexural; impact; hardness where implements on the composite specimens. The influence of filler consists of two metals (W)and (Ni) on mechanical behavior of epoxy (SikadurR-52) was studied .The study deal with two types of mixtures of specimens, the first one consists of epoxy and one of metal filler (nickel) or (tungsten) alone in different weight percentage (0% , 2% , 5%) and the second deal with metal fillers of (Ni &W ) mixing together to study the influence mixture in mechanical behavior of epoxy. All tests carried out at room temperature and according to ASTM standards. The results indicated improvement in mechanical behavior of epoxy (Sikadur-52) especially at specimen prepared of composite (5%wt) of (W+Ni) casting together mean (2.5%wt of W and 2.5%Ni).
