Description

Copper-Zinc Alloy Nanopowder Ca. 60/40 is a high-purity, engineered nanomaterial composed of a fine particulate mixture of copper and zinc, typically in a ratio approximating 60% copper to 40% zinc. This material matters for its unique catalytic, electrical, and thermal properties, which are significantly enhanced at the nanoscale. It is primarily needed by industries involved in advanced catalysis, conductive inks and pastes, metallurgy, and the development of novel composite materials.

Application

• Catalysis: Acts as a highly active and selective catalyst or catalyst precursor for methanol synthesis, water-gas shift reactions, and selective hydrogenation processes.
• Conductive Materials: Used in the formulation of conductive inks, pastes, and adhesives for printed electronics, flexible circuits, and RFID tags.
• Metallurgy & Sintering: Serves as a nano-additive to improve the sintering behavior, density, and mechanical properties of metal matrix composites and alloys.
• Antimicrobial Coatings: Incorporated into surface coatings and polymers to impart antimicrobial properties, leveraging the biocidal effects of copper and zinc ions.
• Chemical Synthesis: Employed as a reactive precursor in solid-state synthesis and the production of other metal-organic frameworks or complex alloys.
• Thermal Interface Materials: Enhances the thermal conductivity of greases, pads, and epoxies used in electronics cooling applications.
• Gas Sensors: Utilized in the fabrication of sensitive layers for detecting gases like carbon monoxide or volatile organic compounds (VOCs).
• Research & Development: Serves as a key material for academic and industrial R&D in nanotechnology, materials science, and chemical engineering.

Quality Control

Our Copper-Zinc Alloy Nanopowder is manufactured under controlled conditions and undergoes rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Key parameters such as particle size distribution, elemental composition, and phase purity are strictly monitored. A comprehensive Certificate of Analysis (COA) detailing these specifications is available with each shipment and upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its properties of being easily oxidized (store under inert atmosphere) and hygroscopic (moisture-sensitive), this material must be stored under an inert gas (e.g., argon or nitrogen) in a cool, dry place. Recommended storage temperature is 15-25°C. The container must be kept tightly sealed to minimize exposure to air and moisture.
