Description of Inconel 718 Spherical Powder
Nickel-Based Alloy Inconel 718 is primarily composed of nickel (approximately 50-55%), with significant additions of chromium, niobium, molybdenum, and smaller amounts of titanium and aluminum. These elements contribute to its high strength, corrosion resistance, and excellent mechanical properties at elevated temperatures.
Inconel 718 spherical powder combines advanced alloy properties with tailored powder characteristics, making it a preferred choice for high-performance applications requiring strength, corrosion resistance, and precision in additive manufacturing (3D Printing).

Selective laser melting of Cu-inconel 718 powder mixtures
- The selective laser melting of mechanically mixed Inconel 718 and copper powders is studied by processing feedstocks of different Cu content at various energy inputs. It was observed that with the increase of the Cu content the width of the molten pools decreases while the porosity of the samples increases.
Inconel 718 may be produced through the following processes: Annealing: The metal is exposed to heat and then gradually brought down to lower temperature. This gives the material its strength and resistance to stress.
Composition: Inconel 625 has higher nickel and chromium content compared to Inconel 718, which has more niobium and titanium.
Properties: Inconel 625 offers superior corrosion resistance, while Inconel 718 excels in high-temperature strength and fatigue resistance.
Applications: 625 is used in marine and chemical environments, while 718 is preferred for aerospace and high-temperature industrial applications.
Inconel powder, like Inconel 625, is not flammable under normal conditions. It’s made of metals like nickel and chromium, which don’t burn easily. However, handling any fine metal powder requires safety precautions to avoid fire hazards from sparks or high temperatures.
