Unwrought Copper Cathodes (99.99%)

Description

Product Overview
Unwrought Copper Cathodes (99.99%) are high-purity, refined copper plates produced via advanced electro-refining, compliant with global standards such as LME Grade A. They serve as the essential raw material for manufacturing semi-finished copper products (rod, wire, tube, sheet) across electrical, construction, and industrial equipment sectors. The key value proposition lies in delivering maximum electrical conductivity (>101% IACS) and minimal impurity interference, directly reducing energy loss and boosting downstream yield. Strategically, securing this grade ensures supply chain resilience and cost efficiency amid rising green electrification demand.

Key Specifications & Technical Characteristics

• Chemical Composition: Cu ≥ 99.99%; impurities (including Ag, Pb, Se, Te, Bi, Sb, As, Fe, Sn, Ni, S) ≤ 100 ppm total

• Purity Grade: LME Grade A equivalent (ASTM B115, BS6017)

• Physical Form: Flat, trapezoidal or square plates; clean metallic pink to red color; thickness ~25–50 mm; weight per plate ~100–150 kg

• Packaging Options: Palletized strapped bundles (approx. 1–2 MT per package), shrink-wrapped and banded for sea freight; optional anti-tarnish treatment

• Shelf Life: Indefinite when stored indoors in dry, non-corrosive conditions; no chemical degradation over time

Core Industrial Applications

• Wire & Cable manufacturing: Drawn into high-conductivity electrical wire for power transmission, renewable energy systems (solar, wind), and EV charging infrastructure – superior ductility reduces breakage during drawing.

• Copper rod & tube production: Used for plumbing, HVAC, and heat exchangers – 99.99% purity minimizes hydrogen embrittlement in hot-forming processes, extending end-product lifespan.

• Busbar & switchgear fabrication: Low impurity levels ensure consistent resistivity and thermal stability under high load, reducing failure risk in industrial control panels.

• Cost advantage: Higher purity lowers refining and alloying adjustments for downstream processors, directly improving melt efficiency by 2–4%.

Competitive Advantages

• Quality consistency: Full batch traceability with independent ISO 17025 lab verification; deviations from 99.99% purity trigger automatic rejection.

• Supply reliability: Backed by long-term mine-linked contracts; 24/7 export control tower with real-time inventory updates.

• Logistics capability: Pre-bundled for direct container loading; lead times as low as 7 days ex-warehouse (Rotterdam, Busan, Houston).

• Price competitiveness: LME-linked pricing with flexible monthly index or fixed formulas; volume discounts and hedging support.

• Sustainability: Available with low-carbon certification (scopes 1 & 2 <0.15 t CO2/t Cu) and full conflict-free mineral reporting.

Commercial & Supply Information

• Minimum Order Quantity (MOQ): BULK 20MT (20 metric tons) per shipment
