Titanium has been identified as a key material to reduce the weight of automotive components and thereby reduce fuel consumption. In this paper, we focused on three different kinds of titanium commercially pure powders-DUP, TP and R, two types of lubrication method-die wall lube and inter-particle lube, compressed them to the same green density, and sintered the specimens at 2150°F (1177°C) or 2300°F (1260°C). Mechanical properties were evaluated using flexural, hardness and tensile tests. TP powders gave a good combination of mechanical properties with high strength and high elongation for both lube methods. R specimens show highest strength, relative density and hardness. DUP specimens show the lowest hardness and strength. Higher sintering temperature provides rounded pores and better mechanical properties. Oxygen equivalence content provides a good correlation with mechanical properties.
