Ni3Al is an intermetallic compound which has unique property with temperature. Annealing is done at temperature 300, 500, and 700°C for 1 hour and analyzed with X-ray Diffraction (XRD) and Energy Dispersive X-ray (EDX) analysis for their crystallographic nature. EDX confirmed the composition of Ni3Al with exact stoichiometry, where as the XRD confirmed the crystallographic nature of the material. The mechanical properties by hardness results showed that Ni3Al have highest Vickers hardness value of 554 HV when it is non-heat treated. Its hardness drop as it had undergoes annealing process. Corrosion analysis by tafel test shows that its polarization resistance may increase up to 4145  cm2 when annealed at high temperature. These results show that Ni3Al is a promising material to be considered as an alternative automotive body.
