Ultra-Fine Copper Powder — 800 Mesh & 3000 Mesh

Chemically produced superfine copper powder with spherical morphology and high surface activity — the best of both atomized fluidity and chemical reactivity.

① 800 Mesh Copper Powder

Made by chemical synthesis, our superfine copper powder features a spherical or approximately spherical shape. SEM imaging of single particles reveals a porous microstructure.

These two characteristics give our superfine copper powder the same fluidity as atomized powder, while simultaneously maintaining the high active performance of chemically produced powder.

Whether in the field of powder metallurgy or catalyst applications, our copper powder offers irreplaceable advantages over conventional atomized and electrolytic powders.

② 3000 Mesh Copper Powder

Ultra-fine copper powder for the most demanding applications. Grades from standard to ultra-fine with D50 as low as 2.0-3.0 µm.
