🏭 Manufacturing Process & Quality Control
1️⃣ Raw Material Selection
Only premium-grade electrolytic copper cathodes are used as the base material, ensuring the foundation of 99.999% purity.
2️⃣ Vacuum Melting
The copper is melted under vacuum or inert gas to avoid oxidation and minimize gas absorption.
3️⃣ Controlled Granulation
The molten copper is rapidly cooled and atomized to form uniform granules, achieving consistent particle size distribution.
4️⃣ Sieving & Particle Classification
Granules are screened to achieve the required mesh size, suitable for applications ranging from <1 mm to 10 mm.
5️⃣ Final Inspection & Packaging
Every batch undergoes strict testing, including conductivity measurement, microscopic inspection, and chemical analysis. The final product is vacuum-packed in anti-static bags or sealed containers to prevent contamination.
🔬 Key Applications
🧪 Laboratory Research – Ideal for metallurgical studies, alloy development, and thermal conductivity experiments.
⚡ Electronics Manufacturing – Used in conductive adhesives, high-performance wiring, and semiconductor connections.
🔩 Alloying Agent – Blended with other metals to create specialized alloys for aerospace, automotive, and marine industries.
🔥 Thermal Management Systems – Suitable for heat sinks, spreaders, and high-performance cooling devices.
🚀 Aerospace & Defense – Applied in high-reliability systems requiring maximum conductivity and corrosion resistance.
High purity copper granules are widely used in electronics, aerospace, metallurgy, and renewable energy due to their exceptional conductivity and corrosion resistance.
