Inconel 718 Powder Description

Inconel 718 (Alloy 718, UNS N07718) is a high-strength, corrosion-resistant nickel-chromium material used at -423° to 1300°F. The age-hardenable alloy can be readily fabricated, even into complex parts. Its welding characteristics, especially its resistance to post-weld cracking, are outstanding.

The ease and economy of the fabrication of INCONEL 718, combined with good tensile, fatigue, creep, and rupture strength, have resulted in its use in a wide range of applications. Examples of these are components for liquid fueled rockets, rings, casings and various formed sheet metal parts for aircraft and land-based gas turbine engines, and cryogenic tankage.

Furthermore, Inconel 718 Powder plays an important role in additive manufacturing (3D printing).

Inconel 718 Powder Applications

Inconel 718 Powder plays an important role in additive manufacturing (3D printing). IN718 was firstly designed and introduce to overcome the poor weldability of superalloys in the 1960s. But now IN718 is being used intensively in gas turbines and aero engines for discs and frames. Due to IN718’s excellent weldability and similarity of the AM and welding processes, IN718 has been widely applied in metallic AM fields to understand the fundamentals of AM processes.

FAQ

  • Metal powders are fine particles of metals produced through various processes such as atomization, reduction, or electrolysis. They are used in applications like additive manufacturing, powder metallurgy, and coatings.

  • Alloy powders consist of two or more metallic elements combined to enhance properties like strength, corrosion resistance, and ductility, whereas pure metal powders contain only a single element.

  • The shape affects flowability, packing density, and spreadability. Spherical particles are preferred in additive manufacturing due to their superior flow characteristics.

  • Spherical powders are typically produced using gas atomization, where molten metal is atomized into fine droplets that solidify into spherical shapes.

  • Spherical powders offer better flowability and packing density, leading to improved layer uniformity and mechanical properties in 3D-printed components.

  • Factors include particle size distribution, shape, chemical composition, purity, and production method.

  • Yes, metal powders can pose hazards such as toxicity, reactivity, combustibility, and instability. Proper handling, storage, and safety protocols are essential.

  • In powder metallurgy, metal powders are compacted and sintered to produce components with complex shapes and tailored properties, often with minimal waste.

  • Yes, unused or excess metal powders from manufacturing processes can often be collected, sieved, and reused, provided they meet quality standards.

  • The combination of different metals in alloy powders can enhance properties such as strength, hardness, corrosion resistance, and thermal stability, depending on the application requirements.

  • Spherical alloy powders are used in aerospace, automotive, medical implants, and tooling industries for manufacturing high-performance components via additive manufacturing and powder metallurgy.

Production methods like gas atomization, water atomization, and mechanical milling influence particle size, shape, and purity, which in turn affect the performance of the powders in various applications.
