Precious metals, PGM group, rare earth metals, and engineered copper.
Mox Core works across the full precious-metals complex, the platinum-group metals (PGMs) we handle, a set of other industrial metals, and the rare earth metals (REMs), plus a growing line of high-purity copper nanomaterials verified in our own lab.
Gold & silver
Core holdings for reserve, investment, and industrial-grade demand — sourced, assayed, and delivered against the specification your corporation requires.
Gold
Bullion and doré sourcing with purity verified to 99.99% (four nines) on request, documented with a certificate of analysis.
Silver
Investment and industrial-grade silver, assayed for purity and suited to both reserve positions and manufacturing feedstock.
The PGM group we handle, assayed on our own bench.
Platinum-group metals carry disproportionate value in small volumes, which makes independent verification essential. Mox Core assays each of the following five PGM elements in-house before it trades.
Beyond the PGM group.
Mox Core also sources and trades a set of other industrial metals used across electronics, alloying, and manufacturing supply chains.
Tantalum
High-melting-point transition metal used in capacitors, aerospace alloys, and chemical processing equipment.
Tin
Base metal used in solder, tinplate, and a wide range of alloying applications.
Tungsten
Extremely high melting point and density, used in tooling, hardmetals, and high-temperature applications.
Copper
Bulk and engineered copper across grades — from industrial wire and cable stock to the high-purity nanopowder line detailed below.
Aluminum
Lightweight structural and conductive metal sourced for industrial and manufacturing applications.
All seventeen rare earth elements, sourced and verified.
Rare earth metals underpin magnets, catalysts, and advanced electronics, and demand the same traceability corporations expect from precious metals. Mox Core sources and can verify the full REM group — light and heavy rare earths alike — against client-defined purity specifications.
Magnet metals
Neodymium, praseodymium, dysprosium, and terbium for permanent-magnet and motor applications.
Catalysis & glass
Cerium, lanthanum, and related light rare earths for catalytic converters, polishing compounds, and specialty glass.
Electronics & energy
Yttrium, europium, and other REMs supporting phosphors, batteries, and advanced electronics manufacturing.
High-purity copper nanopowder, 5N–7N
Copper nanopowder engineered for applications that demand exceptional metallic purity and controlled particle size, produced and verified across the 5N (99.999%) to 7N (99.99999%) purity range.
Sub-micron particle populations are confirmed independently using Nanoparticle Tracking Analysis (NTA), giving corporate buyers a documented particle-size distribution alongside the purity grade.
| Grade | Purity | Typical use |
|---|---|---|
| 5N | 99.999% | Standard high-purity grade |
| 6N | 99.9999% | Advanced electronics & catalysis |
| 7N | 99.99999% | Ultra-high purity / research grade |
Where 5N–7N copper nanopowder is used
Conductive inks & pastes
Printed electronics, RFID antennas, and low-temperature sintering pastes benefit from high surface area and low sintering onset temperature.
Catalysis
High-purity, high-surface-area copper used as a catalyst and catalyst precursor in organic synthesis and electrochemical applications.
Advanced coatings
Nanoscale copper enables thin, uniform coatings with antimicrobial and thermally conductive properties.
Additive manufacturing
Fine, controlled particle-size powders support metal 3D-printing and powder-metallurgy feedstocks.
Research & reference standards
7N-grade material supports analytical calibration and fundamental nanoscience research.
Electronics & thermal management
Ultra-low trace-metal content supports semiconductor-adjacent and high-reliability electronics use.
