Given its electrical conductivity and its excellent resistance to salt and water corrosion, bronze is still widely relevant in marine applications as well as in water propulsions and handling systems .
The mechanical properties at room temperature of Cu-10Sn bronze samples are presented that were built by selective laser melting using gas-atomized powders with average particle size 85+/-15 μm . They are compared to the benchmark characteristics of samples produced using casting. Using an SLM 250HL machine, samples built under argon atmosphere (using the following optimized processing parameters : scanning speed 210mm/s, laser power 271W, powder layer thickness 90μm and hatch distance 90μm) exhibit 99.7% density, measured using the Archimedes technique. The mechanical properties of Cu-10Sn depend directly of the microstructure formed during solidification  with no need for post-heat treatment.
Although the phases available are essentially similar – both microstructure exhibit dendrites of the alpha-Cu(Sn) phase along with an interdendritic (alpha+delta)-eutectoid - the refined SLM microstructure compared to the coarser cast microstructure is due to the faster cooling rate during solidification and significantly affects the mechanical properties:
These SLM properties are comparable to those of Cu-10Sn-2Zm-1.5Fe bronze cast alloys strengthened by iron nanoparticles .
