Our Expertise, Your Advantage
Copper cathodes are a fundamental product in the copper production process, widely used in high-performance applications across various industries. These cathodes are produced through an advanced electrolytic refining process, where pure copper is extracted from raw materials, resulting in copper squares typically weighing between 50 and 80 kg.
Renowned for their exceptional purity, copper cathodes boast a copper content of at least 99.99%. This level of quality meets the strictest international standards, such as LME Grade A, Cu-CATH-1 (EN 1978), and Copper Cathodes Grade 1 (ASTM B115). Certified production processes also adhere to ISO 9001 and ISO 14001 standards, ensuring consistent quality and sustainability.
With minimal impurity levels, these cathodes offer superior conductivity, making them ideal for a variety of high-tech applications. Their purity and consistency make them a key material traded on platforms like the London Metal Exchange (LME) and Comex.
Our copper cathodes provide the foundation for premium copper products, trusted by industries worldwide for their reliability and performance.
