• Additive Manufacturing & 3D Printing: Used to create complex, high-resolution parts with excellent electrical and thermal conductivity. The spherical shape and fine size ensure smooth layer deposition and high-density prints.
• Laser Cladding & Thermal Spraying: Serves as a coating material to enhance surface properties of components, providing superior wear resistance, corrosion protection, and improved thermal/electrical characteristics.
• Powder Metallurgy (PM) & Metal Injection Molding (MIM): Enables the production of net-shape or near-net-shape parts with fine details and good mechanical properties, ideal for high-volume manufacturing.
• Hot Isostatic Pressing (HIP): Used in HIP processes to eliminate porosity in castings and consolidate metal powders into fully dense, high-integrity components for critical aerospace and medical applications.
• Aerospace & Automotive: Applied in the manufacturing of high-temperature structural materials, engine components, and various spacecraft parts where material performance and reliability are paramount.

The high-quality spherical copper powder is primarily produced via the Plasma Rotating Electrode Process (PREP):

1. Melting: A solid copper electrode rod is rapidly rotated at high speed. Its end face is melted by a high-temperature plasma arc, forming a thin layer of liquid metal.
2. Atomization: Centrifugal force from the high-speed rotation causes the molten liquid to be ejected and broken up into numerous fine, uniform droplets.
3. Spheroidization & Solidification: As these tiny droplets travel through the inert gas atmosphere, surface tension pulls them into perfect spheres. They solidify rapidly mid-air before collection, resulting in spherical powder with high sphericity, no hollow particles, and very low oxygen content.

Store in tightly closed containers in a dry, well-ventilated place. Vacuum packaging available for optimal preservation.

A1: While both are atomization methods, PREP (Plasma Rotating Electrode Process) 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 for critical applications like 3D printing.

A2: A spherical shape is critical for applications like 3D printing and Metal Injection Molding (MIM) because it ensures excellent powder flowability. This allows for uniform spreading and packing, leading to higher density, better surface finish, and more consistent mechanical properties in the final product.

A3: Yes, our production process allows for effective control over the particle size distribution. We offer standard ranges like 15-45µm but can customize the size to meet specific application requirements, ensuring optimal performance for your process.

A4: The low oxygen content is achieved through an inert gas atmosphere during the atomization and subsequent two-step treatment processes. Low oxygen is vital as it prevents oxidation, which can degrade the powder's electrical conductivity, solderability, and overall mechanical performance in the final component.

A5: Our annual production capacity is 5000 kg. Standard packaging is in plastic bags placed within cartons or iron drums to ensure the powder is protected from moisture and contamination during transport and storage.
