Description
Copper (Cu) Micron Powder – Spherical (99.99%, 1 µm)
Copper (Cu) Micron Powder is a high-purity spherical metallic powder with an average particle size of 1 µm and purity of 99.99%. Known for its exceptional electrical and thermal conductivity, corrosion resistance, and ductility, this powder is widely used across electronics, aerospace, metallurgy, pigments, and additive manufacturing.
The spherical morphology ensures superior flowability, uniform packing, and sintering behavior, making it highly suitable for powder metallurgy, conductive inks, coatings, and high-performance electronic applications. With a cubic, face-centered crystal structure (FCC) and fine micron scale, it provides both excellent performance and processability.
