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.
