Spherical Inconel 718 Powder Description:
Inconel alloy is a family of nickel-chromium superalloys and a trademark of Special Metals Corporation. It is typically used in high-temperature applications. Inconel alloy 600 (UNS N06600) is often used for applications that require resistance to corrosion and heat.
Spherical Inconel 718 powder is a high-performance nickel-chromium alloy in powdered form, designed primarily for use in additive manufacturing and other powder metallurgy processes like Metal Injection Molding (MIM). The spherical morphology of the powder enhances its flowability and packing density, making it suitable for applications where precise and uniform layer deposition is critical, such as 3D printing.
SAM's spherical Inconel 718 powder has low oxygen content, high purity, excellent flowability, high apparent and tap densities, and a perfectly spherical shape, which could be used in 3D printing.
