Copper Powder 99.3%, General Purpose, 150 Mesh
The most popular and widely used copper powder, produced by the water atomization method followed by hydrogen reduction. This general-purpose copper powder has diverse applications, including the production of copper compounds, use as a catalyst in chemical formulations, abrasive wheels, carbon brushes, and more. It is important to note that pure copper powders may not exhibit continuity or conductivity under low-voltage multimeter tests due to air gaps and weak particle contacts but will show conductivity under higher voltage, when compacted, or mixed with oils/resins to form a paste.
