In this study, it is aimed to produce various composites and reveal their physical properties. Tungsten carbide (WC) powder and the two of cobalt (Co) and titanium (Ti) powders as binder phase have been used for the preparation of WC-Co-Ti ceramic-metal composite with powder metallurgy.  Two different ultrasonic non-destructive techniques were employed to measure the mechanical wave velocity in WC-Co-Ti composites. The study was performed on various specimens with different WCx content at the range from 60 to 80% and Co/Ti content in 3:1, 1:1 and 1:3 groups. The WCx content in examined materials was determined using the standard destructive analysis. The Young modulus (E) of the produced composites and the ultrasonic velocity measured through ultrasonic pulse-echo method and immersion method. Thermal conductivity of samples has been measured via hot disk method. The relation between the Young modulus' values with ultrasonic wave velocity,  which is obtained through two different methods and thermal conductivity has been physically examined and the results have been compared with the literature.
