Ultradispersed Ultrafine Copper Powder (5N/99.999% & 6N/99.9999% Oxygen-Free)
Isotopic composition: Cu-63: 69.09% +/- 0.05% Cu-65: 31.91% +/- 0.05%

Ultrafine high-purity copper powder is supplied as a finely dispersed metallic powder, typically featuring a controlled spherical or dendritic particle morphology and grain size in the micrometer or sub-micrometer range. Engineered for uniform dispersion, high surface area, and predictable sintering behavior, this form factor is ideal for advanced applications such as powder metallurgy, additive manufacturing, microelectronics, and catalysis.

The performance of ultrafine high-purity copper powder is directly influenced by the presence of impurities. Even minimal traces of elements like oxygen, chromium, vanadium, manganese, titanium, zirconium, or niobium can significantly reduce the materialâ??s conductive efficiency. This is why tight control of composition and oxygen content is essential during production, particularly for use in microelectronics, vacuum devices, energy systems, and other high-tech applications.

Ultra High-Purity 6N Copper Ingots (99.9999% Oxygen-Free)

Fine 1 kg copper ingots, each individually sealed in polyethylene wrap to prevent surface oxidation.
HS code (for customs) - 7403.11.00 Cathodes and sections of cathodes of refined copper (high-purity)
Available delivery terms (Incoterms 2020) - EXW (Ex Works) - FCA (Free Carrier) - DAP (Delivered at Place)

These physical and chemical characteristics, along with excellent mechanical strength and ductility, make high-purity copper indispensable for advanced electronics and precision engineering. However, the performance of copper in such applications is highly sensitive to impurity levels. Even trace amounts of elements like oxygen, chromium, vanadium, manganese, titanium, zirconium, or niobium can degrade its conductive properties.

Product Form and Handling
High-purity copper is typically supplied as trapezoidal ingots â?? compact, brownish-red blocks engineered for controlled remelting, processing, or storage. While similar in appearance to bars, copper ingots are specific to non-ferrous metallurgy and precision-grade production workflows. Each ingot is individually sealed in inert or protective packaging to prevent surface oxidation and ensure purity preservation during transit and storage.

Ultra high-purity copper, valued for its exceptional electrical conductivity, thermal performance, and biocompatibility, is essential in advanced technologies. For critical industrial and scientific use, purity levels of 99.999% (5N) and above are required.
