Přehled prášku Inconel 625
Prášek Inconel 625 is a nickel-based superalloy that possesses high strength properties and resistance to elevated temperatures. Inconel 625 (Alloy 625, UNS N06625) is widely used for its high strength, excellent fabricability (including joining), and outstanding corrosion resistance. Its service temperatures range from kryogenní to 1800°F (982°C). High tensile, creep, and rupture strength, outstanding fatigue and thermal-fatigue strength, oxidation resistance and excellent weldability and brazeability are the properties of INCONEL alloy 625 that make it interesting to the aerospace field.
Inconel 625 powder is a high-performance nickel-based superalloy powder widely used in additive manufacturing (AM) and traditional metalworking processes. Known for its exceptional strength, corrosion resistance, and thermal stability, this material is a top choice in industries such as aerospace, energy, and marine engineering.
But what makes Inconel 625 powder stand out? Its unique composition, primarily consisting of nickel, chromium, and molybdenum, provides outstanding resistance against oxidation, pitting, and creep deformation. This makes it ideal for high-temperature and high-stress applications where ordinary materials would fail.
With the rise of metal 3D printing, the demand for high-quality Prášek Inconel 625 has skyrocketed. Companies like Met3DP are at the forefront, supplying industry-leading rozprašovaný plyn a PREP-produced spherical powders optimized for Selektivní laserové tavení (SLM), Tavení elektronovým paprskem (EBM), Vstřikování kovů (MIM)a další pokročilé výrobní techniky.
