The high strength and low density of titanium and its alloys have from the first ensured a positive role for the metal in aero-engine and airframe applications. It is difficult to imagine how current levels of performance, engine power to weight ratios; airframe strength; aircraft speed and range and other critical factors could be achieved without titanium. Cu and its alloys usually combine excellent  properties of high thermal and electrical conductivity, high ductility and corrosion-resistance, and some Cu alloys also exhibit a high strength.  This study examines the effect of adding copper to titanium by powder metallurgy. 1.0,, 1.5, 2.0 and 2.5% copper, balance titanium specimen in 0.5 been compressed. Grading was performed laser and SEM powder. Measured green density and sintered. In the sintered samples used metallographic analysis, laser diffraction, microhardness.

Key words: powder metallurgy; titanium alloy; Ti-Cu.
