The present research work influences micro-alloys in the bronze alloy, studies the classification bronze Cu1, Cu2, Cu3 and Cu4, defines the structures to the molten state of the materials used in the manufacture of propellers for use in the naval industry . Chemical compositions, metallographic structures, limitations of chemical elements in mechanical properties, as well as limitations of chemical elements in welding processes are defined. The alloy tested, a bronze cast aluminum corresponds to the classification of the complex polyphasic aluminum subgroup 3 or Cu3 classification, NiAl bronze, has an average tensile strength of 64.86 kg / mm2, and an elongation in two inches of 24, 5, the metallographic structure phases are observed: a, a + g2 and k. The corrosion test with the Potentiostat PS4 equipment indicates a corrosion density of 0.38 mA / cm2, the activity in synthetic seawater being cathodic.Downloads
