Description
Overview
Copper micro powder is known for its distinctive reddish hue and exceptional resistance to corrosion, ensuring durability in challenging conditions. With its soft, malleable nature, this finely ground powder consists of spherical particles averaging less than 7 microns in diameter, allowing for smooth integration in various processes. The powder’s structure adapts effectively under pressure, making it an ideal choice for high-precision environments such as electronics, conductive coatings, and advanced manufacturing applications where consistency and performance are critical.
Properties
- Composition: Typically 99.5% or higher pure copper.
- Density: ~8.94 g/cm³ (bulk density lower, ~1–5 g/cm³ depending on particle size)
- Melting Point: 1,085°C (1,984°F).
- Color: Reddish-orange, may appear darker or brownish due to particle size and oxidation.
- Particle Size: Varies widely, typically 1–100 micrometers.
- Malleability: Not applicable in powder form, but copper is inherently malleable.
- Electrical Conductivity: High when compacted, ~97–100% of bulk copper’s conductivity.
- Thermal Conductivity: Good, ~400 W/(m·K) when consolidated, lower in loose form.
- Corrosion Resistance: Susceptible to oxidation, forms copper oxide on exposure to air.
Applications
- Nanotech
- Microelectronics
- Military-grade tech
- Catalyst development
- Friction materials (clutches/brakes)
- Metal injection molding (MIM)
Packaging options
Standard Format:

Market outlook
Copper powder demand is growing with additive manufacturing and electronics. Prices are ~$15–$25/kg, influenced by global copper supply (Chile, Peru dominate). Supply chain disruptions and energy costs are risks, but recycling is increasing.
Purchase & Compliance
Batches include a certificate of analysis for purity and particle size. Third-party testing is available. KYC may be required for bulk orders due to industrial regulations.
