%X Al-Co-Mn alloys with different atomic percent were synthetized by induction melting technique. Controlled annealing treatment was applied to the resultant alloys under He atmosphere. Different microstructures were produced as a function of the Mn and Co content producing different grain morphologies. Hardness results indicate an increment in approximately 30 percent (150 kg/mm<sup>2</sup>) in samples with low cobalt and high aluminum; while fracture toughness evaluations present a noticeable increment for these samples of 50 MPa&#8729;m<sup>1/2</sup> which represents an improvement of approximately five times more than sample with higher aluminum content. Electrical conductivity value, higher than 61.8% IACS was obtained in sample with high Co and low Al content. Electrical characterization was developed to observe the alloy performance as anodic element in a primary battery. Results are interpreted considering mainly a substitutional mechanism.
