Copper

Copper (CAS 7440-50-8), abbreviated Cu and approved as food colorant E115, is a base metal supplied in refined elemental form for industrial, agricultural, and chemical processing applications.

Where is Copper used?

• Water treatment: algaecide and antifouling systems controlling microbial growth in cooling towers, reservoirs, and distribution infrastructure
• Agriculture: fungicides and soil amendments for crop disease management
• Livestock feed: correction of mineral deficiencies
• Electronics and surface finishing: electroplating, conductive coatings, and printed circuit board fabrication
• Chemical processing: catalyst or catalyst precursor in hydrogenation, oxidation, and organic synthesis reactions
• It functions as a biocide, catalyst, and conductive material across manufacturing and treatment processes.

Commercial specifications

• Purity grades range from standard technical to high-purity electrolytic (99.99%).
• Powder grades in varying mesh sizes for catalyst preparation, pigment blending, or metallurgical applications.
• Commercial grades include electrolytic tough pitch (ETP) and oxygen-free (OF) copper for electrical and precision uses.
