Recently, developing new alloys of Tungsten heavy (WHA) is the most important issue that researchers considered due to their wide applications of radiation protectors, vibration absorber, kinetic energy penetrators and heavy-duty electrical contacts. The present work shows 9 different Tungsten alloys with a variety of weight percent’s from "Graphene" as a Nano- particle additive. The proposed alloys produced by minimizing manufacturing parameters by applying the Taguchi technique. In addition, this work used to relate the Powder-Metallurgy (PM) parameters such as Sintering Temperature (ST) level, the weight % of the added Nano-particle of Graphene (Gw) and the type of Process Control Agent (PCA) with the mechanical characteristics such as Young’s modulus, modulus of Bulk, modulus of Shear, Poisson's number, Vickers hardness, Grain size , Relative Density. The results showed that specimen number 8 is given higher values of modulus of elasticity, reached 326.2 GPa, bulk value of 255.64 GPa, and shear value of 126.7 GPa with PM preparation condition at 15000C sintering temperature, stearic acid as a process control agent (PCA) and 0.0 %Wt. of Graphene.
