Semiconductor Grade Copper Appraisal

Ultrafine Copper Powder (99.9999% Purity)

This item is a 2 kg PET (Polyethylene terephthalate) container housing 'COPPER POWDER ULTRAFINE'. The visible portion shows a cylindrical, reddish-orange or salmon-colored canister with a prominent white adhesive label. The label provides precise technical specifications, indicating a chemical purity for Copper (Cu) of 99.9999%, which is a high-grade industrial or scientific material. It lists trace impurities including Li, Be, Ti, V, Ni, Co, Rb, Mo, Pd, and Cd, stating they comprise not more than 0.0001% by weight. A specific isotropic analysis is provided, noting Cu63 at 69.09 ± 0.05% and Cu65 at 30.91 ± 0.03%. The label also contains a technical standard or tracking number 'TU 24.44.21-003-59861625-2024', suggesting a very recent production date in the year 2024. The canister appears to be in new, pristine condition with no visible wear, scuffing, or damage to the label or container body. Such high-purity materials are typically used in specialized applications like microelectronics, chemical catalysts, or advanced metallurgy. The craftsmanship is industrial, focused on precision and containment integrity.
