Frequently Asked Questions

Find answers to common questions about copper foam and our services.

Where can I buy copper foam for battery research?

PrometheanFoam supplies high-purity copper foam worldwide. Order our $79 sample kit or request a custom quote for research quantities starting at 10 sheets. We ship to 50+ countries with 3-5 day delivery to the US. For bulk production orders, we offer competitive pricing with MOQ starting at 100 sheets.

What is the price of copper foam per square meter?

Copper foam pricing varies by specification (purity, PPI, thickness). Standard 99.5% pure, 110 PPI foam ranges from $120-180/m² for production volumes (100+ sheets). Research-grade 99.9% pure copper foam starts at $200/m². Contact us for current pricing based on your specific requirements and volume.

What's the minimum order quantity for copper foam?

For samples: 1-5 sheets (starting at $79 for our sample kit). For production: 10 sheets minimum for standard specifications, 100 sheets for custom specifications. Larger volumes receive volume discounts - contact our sales team for specific MOQ based on your application requirements.

What is the difference between 90 PPI and 110 PPI copper foam?

PPI (pores per inch) affects surface area and permeability:

  • 90 PPI: Larger pores (~0.28mm), higher permeability, better for thick electrodes and filtration
  • 110 PPI: Smaller pores (~0.23mm), higher surface area, optimal for most battery applications
  • 130 PPI: Finest pores (~0.20mm), maximum surface area, for supercapacitors and catalyst supports
For lithium-ion battery anodes, 110 PPI is typically optimal.

Can copper foam be used in alkaline environments?

While copper foam has good corrosion resistance, it's not recommended for highly alkaline environments (pH >10). For alkaline applications such as nickel-metal hydride batteries or alkaline fuel cells, nickel foam is preferred. Copper foam excels in neutral to slightly acidic conditions typical of lithium-ion batteries and PEM fuel cells.

What is the thermal conductivity of copper foam?

Effective thermal conductivity ranges from 15-25 W/m·K depending on porosity:

  • 98% porosity: ~15 W/m·K
  • 95% porosity: ~18 W/m·K
  • 90% porosity: ~22 W/m·K
  • 85% porosity: ~25 W/m·K
Compare to solid copper: 400 W/m·K, but foam provides higher surface area for convective heat transfer in thermal management applications.

Is copper foam better than nickel foam for lithium-ion batteries?

For anodes: Yes. Copper foam offers:

  • 2-3x higher electrical conductivity
  • Better lithium plating uniformity (reduces dendrite formation)
  • Lower cost (30-40% less than nickel foam)
  • Compatible with graphite and silicon anode materials
For cathodes: Nickel foam is preferred due to better corrosion resistance in oxidizing environments typical of cathode materials like NMC, LFP, or LCO.

Can copper foam be soldered or brazed?

Yes, copper foam can be joined using several methods:

  • Brazing: Use standard copper brazing alloys (BCuP series) at 700-800°C
  • Soldering: Requires pre-tinning, use high-temperature lead-free solder
  • Laser welding: Possible but requires expertise to avoid pore collapse
  • Conductive epoxy: For low-temperature applications
We provide joining guidelines with sample kits and can recommend optimal methods for your application.

How do you cut copper foam to custom shapes?

Several cutting methods are suitable for copper foam:

  • Scissors/shears: For thin foam (<1mm) in laboratory settings
  • Die cutting: For production volumes (we offer this service)
  • Laser cutting: For complex geometries with minimal edge deformation
  • Waterjet cutting: For thick foam without thermal distortion
  • CNC machining: For precise dimensional requirements
For production volumes, we recommend die cutting for consistency and cost-effectiveness.

Do you provide material certificates for copper foam?

Yes, every order includes comprehensive documentation:

  • Material composition certificate (ICP-MS analysis)
  • ISO 9001:2015 quality certificate
  • RoHS & REACH compliance documentation
  • Test reports (porosity, conductivity, thickness - available on request)
  • Certificate of Analysis with batch/lot number
  • MSDS (Material Safety Data Sheet)
For critical applications (aerospace, medical), we provide additional testing and traceability documentation.

What is the purity of your copper foam?

We offer multiple purity grades:

  • Standard grade: 99.5% minimum purity (typical for industrial applications)
  • Research grade: 99.9% minimum purity (for battery research, publications)
  • High-purity grade: 99.99% available (for specialized applications)
All grades are manufactured using high-purity copper feedstock and verified by ICP-MS analysis. Purity affects electrical conductivity and corrosion resistance.

How is copper foam tested for quality?

Our comprehensive testing protocols include:

  • Purity analysis: ICP-MS (inductively coupled plasma mass spectrometry)
  • Porosity testing: Mercury intrusion porosimetry (ASTM D2856)
  • PPI verification: Microscopy + image analysis (ASTM D3574)
  • Conductivity: Four-point probe method for electrical, laser flash for thermal
  • Mechanical properties: Compression testing (ASTM D1621)
  • Visual inspection: 100% of sheets for defects and consistency
Test reports are available upon request for all production orders.
