Description

Copper Cathode is the primary commercial form of high-purity copper, produced through an intensive electrolytic refining process. Starting from blister copper, the metal is electrochemically purified until it reaches a standard-setting 99.99% purity level, technically classified as Copper Cathode Grade A (Cu-CATH-1). Because of its virtually flawless elemental composition, this material exhibits the highest possible electrical and thermal conductivity ratings among base metals.

Sourced by Metal Mart from world-class, London Metal Exchange (LME) registered brands, our copper cathodes provide local industries with a highly reliable raw material. The flat, rectangular sheets feature exceptionally low levels of impurities (such as arsenic, bismuth, and lead), ensuring that local casting plants, wire drawers, and alloy foundries achieve zero-defect melts, maximum ductility, and peak performance in their finished products.

Key Features:

• Ultra-High Purity (99.99%): Meets Grade A international benchmarks, guaranteeing optimal mechanical and electrochemical stability.

• Peak Conductivity: Provides the maximum possible efficiency for electrical transmission and heat dissipation systems.

• Excellent Drawability: Low impurity profiles allow the metal to be drawn into exceptionally fine wires without fracturing or snapping.

• LME-Registered Standards: Sourced from globally audited producers, ensuring consistent chemical properties across every batch.

Technical Specifications:

• Material Grade: Copper Cathode Grade A (Purity $\ge$ 99.99%)

• Standard: ASTM B115 / BS EN 1978 (Cu-CATH-1)

• Form & Weight: Standard rectangular plates/sheets, bundled and strapped for secure industrial handling.

• Sourcing Network: Directly imported from premier global producers in Chile, Zambia, Australia, and India.

• Quality Verification: Accompanied by certified Mill Test Certificates (MTC) and chemical analysis logs verifying LME compliance.

Common Applications:

• Wire & Cable Manufacturing: Drawing into high-tension overhead cables, household wiring, automotive wiring harnesses, and magnet wires.

• Electrical Engineering: Manufacturing heavy-duty busbars, transformers, switchgears, and electric motor windings.

• Electronics & Technology: Processing into printed circuit board (PCB) copper foils, microprocessors, and high-performance heat sinks.

• Alloy Production: Acting as the essential base element for formulating premium brass, bronze, and copper-nickel industrial alloys.

Through Metal Mart’s established international trade networks, we manage the complete import pipeline—providing full supplier verification, optimized maritime freight, and comprehensive Letter of Credit (LC) facilitation to deliver certified raw materials directly to your factory floor.
