This paper presents Cu90Ni10 alloy properties. These alloys were produced in three distinct modes: alloyed powders (P), powder made from elemental powders of copper and nickel (A); powders from the Cu80Ni20 alloy and an alloying element (D). The influence of time, composition and properties of the powder mixture upon the final properties of the sintered alloys was studied. A comparative study of the sintered compacts obtained by varying the parameters of procedure, compacting pressure and sintering time was performed. The work aimed to research the influence of the parameters above mentioned: density, compressibility, structure of compacts, etc. The sintering capacity was also assessed through the resistence to fracture and hardness of samples, also versus the parameters above mentioned.
