    • Copper (Cu) Nanopowder/Nanoparticles

    When it comes to high-purity copper nanopowder, MK Nano is unmatched. Our copper nanoparticles are superior as they have very good electrical as well as thermal conductivity; thus, they are applicable in various industries and research.

    Copper (Cu) Nanopowder: Product Details

    The copper (Cu) nanopowder that we have contains very small spherical particles, which increase its reactivity due to the high surface-to-volume ratio. It costs less than other metals of the same quality standard.

    We supply copper powder and are trusted for the quality; therefore, we assure you that you will receive a high-quality product tailored to your needs.

    Product Information

    • Purity: 99.9% (metal basis)
    • Appearance: Saddle brown to dark brown powder
    • Morphology: Spherical

    Storage and Cautions

    The high reactivity of copper nanoparticles can lead to combustion. Therefore, they must be handled cautiously without any sudden movements or vibrations. Nanopowder should be packed under vacuum, kept in a cool, dry place, and protected from sunlight, moisture, and air exposure to keep it stable and prevent it from oxidizing.

    Properties of Copper Nanopowder - Features and Benefits

    MK Nano's copper nanopowder has a unique set of features that make it perfect for advanced applications. Our copper powder has a high purity and a controlled particle size, which ensures consistent and reliable performance.

    The primary benefits include:

    Exceptional Conductivity:

    Great for electronics since it has great electrical and thermal conductivity.

    High Catalytic Activity:

    The nanoparticles have a lot of surface area, which makes them a very good catalyst for many chemical processes.

    Antimicrobial Properties:

    Exhibits strong antibacterial and antifungal effects.

    Cost-Effective:

    A less expensive option for conductive uses than gold and silver.
