This paper summarizes the results of a research aimed at assessing the uses of raj koroi (Albizia richardiana) an alternative raw material for plywood production. Five plies raj koroi plywood of 2400 mm×1200 mm×12 mm size was manufactured using urea formaldehyde adhesive. The physical and mechanical properties of the manufactured plywood were evaluated. The results of physical and mechanical properties of raj koroi plywood were compared; data was examined with the existing market available plywood manufactured by simul (Bombax ceiba). It was found that the density of rajkori plywood and simul plywood was 0.75 and 0.50 g/cm3 respectively. The MOR was 62.79 N/mm2 for raj koroi plywood and it was 32.52 N/mm2 for simul plywood. The MOE of raj koroi plywood was found 6997.20 N/mm2 and on the other hand it was 3224.15 N/mm2 for simul plywood. All physical and mechanical properties except thickness, swelling (%) after 24 hours of water soaking of raj koroi plywood were higher than that of simul plywood and which satisfies the standard.
