Industrial Applications
- Additive Manufacturing & 3D Printing: Used to create complex, high-resolution parts with excellent electrical and thermal conductivity.
- Laser Cladding & Thermal Spraying: Serves as a coating material to enhance surface properties of components.
- Powder Metallurgy (PM) & Metal Injection Molding (MIM): Enables production of net-shape or near-net-shape parts with fine details.
- Hot Isostatic Pressing (HIP): Used to eliminate porosity in castings and consolidate metal powders into fully dense components.
- Aerospace & Automotive: Applied in manufacturing high-temperature structural materials and engine components.
Production Process
The high-quality spherical copper powder is primarily produced via the Plasma Rotating Electrode Process (PREP):
- Melting: A solid copper electrode rod is rapidly rotated at high speed while its end face is melted by a high-temperature plasma arc.
- Atomization: Centrifugal force causes the molten liquid to be ejected and broken up into fine, uniform droplets.
- Spheroidization & Solidification: Droplets form perfect spheres that solidify rapidly in an inert gas atmosphere.

Frequently Asked Questions
Q1: What is the key difference between water/gas atomized and PREP copper powder?
A1: PREP typically produces powder with higher sphericity, fewer satellite particles, and virtually no hollow powder due to its centrifugal force-based mechanism, resulting in better flowability and packing density.
Q2: Why is the spherical shape of the copper powder so important?
A2: Spherical shape ensures excellent powder flowability for uniform spreading and packing, leading to higher density and better surface finish in the final product.
Q3: Can you customize the particle size distribution?
A3: Yes, we offer standard ranges like 15-45µm but can customize the size to meet specific application requirements.
Q4: How is the low oxygen content achieved and why is it important?
A4: Achieved through an inert gas atmosphere during atomization. Low oxygen prevents oxidation which can degrade electrical conductivity and mechanical performance.
Q5: What is your annual production capacity, and what is the standard packaging?
A5: Our annual production capacity is 5000 kg. Standard packaging is in plastic bags within cartons or iron drums.
