Basic Information
Custom Rare Metal manufactures high purity Copper Powder and ultrafine copper metal powder with the smallest possible average particle sizes at a competitive price. Our standard powder particle sizes are 1 micron, 3 micron, submicron (<1 micron) and 50-800 nanometer. We can also make Cu powders outside this range as required.
Available Forms
- OFC ultrafine copper powder
- Copper Nanopowder
- High Purity Copper Particles
- High Purity Copper Grain
- High Purity Copper Foil
- High Purity Copper Sheet
- High Purity Copper Alloys
Also, we produce metal copper as cube, pellets, lump, disc and target. High purity copper powder may be purchased in bulk or small quantity.
High Purity Copper Powder Quality Criterion
| Specification | Cu – 4N (99.99%) | Cu – 5N (99.999%) | Cu – 6N (99.9999%) |
| Total Impurities | ≤ 100ppm | ≤ 10ppm | ≤ 1ppm |
| *Our stringent copper powder production processes ensure the absolute minimum amount of impurities including oxygen. Please ask us for further information on which impurities can be controlled to lower levels. | |||

High Purity Copper Powder Applications
Conductive Pastes
Electronic pastes made of ultra-fine copper powder have superior performance and can be used to replace silver pastes on the electrodes of multilayer chip ceramic capacitors (MLCC), round chip ceramic capacitors, varistors and other electronic components, which can significantly reduce the production cost.
Anti-bacterial and Anti-mold Materials
Ultrafine copper particles have a wide range of applications in anti-bacterial and anti-mold of chemical fiber, plastic, rubber, paint, glue and other polymer materials.
High Thermal Conductivity Filler
Nano copper powder is added to epoxy resin, silicone rubber, engineering plastics, coatings and other polymer materials to greatly improve the thermal conductivity of polymer materials.
Lubricating Materials
Copper nanopowder can be added to lubricating oil to change the friction performance of machinery, and also repair the microscopic defects on the friction surface.
Activated Sintering Additives
Ultra-fine copper metal powder is an effective sintering additive that significantly reduces the sintering temperature of powder metallurgy products and high-temperature ceramic products, such as binders for diamond and ceramic cutting tools.
High-efficiency Catalyst
Due to the huge specific surface and high activity, ultrafine metal copper powder has strong catalytic effect, replacing conventional copper powder with ultrafine copper powder can greatly improve the catalytic efficiency, and can be used in the production of methanol from industrial water gas to improve the conversion rate.

Customization Production
Please specify desired purity, size, form or drawings. We will let you have NDA and quotation project soon
Even for only 1 kg, it is available for you as well. If there’s no stock, it takes around 3-5 working days to finish the production, but some types need customize then the lead time would be extra 5 working days.
High Purity Copper Highlights
01
High purity, low impurities
Strict control of raw material and guaranteed purity
02
Excellent electrical and thermal conductivity
Resistance has been reduced by 5% and conductivity is close to silver, which is used by our customers in copper-based alloys and targets with excellent thermal conductivity.
03
Super ductility and plasticity
- Take a roll of 6N grade high purity single crystal copper wire for example, the weight is only 1 gram but the length is 1500 meters
- The wire can reach 116 turns in torsion test, while ordinary copper will break after 16 turns.
Packaging, Transport and Storage
- Packaging: packed in a vacuum bags, wrapped in poly-foam box and then cardboard drums for shipping. Other packaging options are available. Clearly tagged and labeled externally to ensure efficient identification and quality control. Great care is taken to avoid any damage which might be caused during storage before transit or during transport.
- Transportation: by Fedex, DHL, UPS with door to door delivery, by Air for urgent order and by Sea for bulk order.
- Storage: store high purity copper powder in a dry, vacuum environment to avoid damage and pollution.
