Pure Copper Powder 53-150 µm

Understanding Pure Copper Powder for Thermal Spray

Pure copper coatings are widely used in industrial surface engineering to impart electrical conductivity, thermal conductivity, or to act as a sacrificial or anti-seize layer. The 53-150 µm particle size distribution is a common specification for thermal spray feedstock, balancing flowability in powder feeders with efficient melting in the spray stream.

This powder is suitable for use in HVOF (High-Velocity Oxygen Fuel), atmospheric plasma spray (APS), and flame spray systems. The final coating properties—such as density, oxide content, and bond strength—depend heavily on the specific spray parameters and substrate preparation. Our team can assist with basic process compatibility guidance when you submit an enquiry.

Typical Coating Applications

While every application requires validation, pure copper thermal spray coatings are typically specified for:

• Electrical contact surfaces: Restoring conductivity on worn components or creating conductive paths on non-conductive substrates.
• Anti-galling and anti-seize coatings: Preventing material transfer and seizure between mating parts, especially in threaded fasteners and sliding components operating at elevated temperatures.
• Corrosion protection: Providing a sacrificial layer in specific corrosive environments, often as part of a multi-layer coating system.
• Artistic and decorative finishes: Achieving a genuine copper appearance on architectural or sculptural elements.

Packaging and Handling

Consistent powder handling is critical for achieving repeatable coating quality. SPA2Z supplies this powder in sealed, moisture-resistant containers to preserve its flow characteristics and prevent contamination during storage and transit.

• 5 kg Tin: Ideal for initial trials, small-scale production, or R&D purposes.
• 10 kg Tin: A convenient size for regular production runs and workshops.
• 25 kg Pail: Cost-effective packaging for high-volume thermal spray operations.

We recommend storing copper powder in a cool, dry environment and minimizing exposure to air once the container is opened to prevent oxidation, which can affect spray performance.
