    Product Description

    Highly pure >99% SPHERICAL COPPER POWDER MADE USING INERT GAS ATOMIZATION. Mesh 400 Spherical Copper.

    HTS Code: 7406.10.0000 
    NMFC: 30743 
    CAS: 7440-50-8

    Additional Description

    Used in Electronics, Injection Molding, Thermal Management, EDM Electrodes, Thermal Spray and other uses where fine spherical powder is needed. 
    Microtrac % passing ....... Micron
    D10   14.5
    D50   20
    D90   25.87

    90% of the particles are 25.87 micron or smaller

    Apparent Density: about 4 g/cc

    Note: Pure copper powders do not show continuity or conductivity by a multimeter. I think there are two reasons for that. One is the low voltage used for the test. The other is lots of air and weak contacts between the particles. They will show conductivity with higher voltage, when they are compacted and when they are mixed with some oil or resin to form a paste.
