Unwrought Copper Cathodes (99.99%)

Description

Product Overview
Unwrought Copper Cathodes (99.99%) are high-purity, electrorefined copper plates essential for downstream conductive material manufacturing. They serve as the primary feedstock for copper wire, rod, and tube production in electrical, construction, and industrial equipment sectors. The key value proposition is unmatched electrical conductivity (≥101% IACS) and contaminant-free performance, reducing energy loss and processing waste. Strategically, this grade secures supply chain resilience for high-volume manufacturers facing tightening LME-grade quality standards.

Key Specifications & Technical Characteristics

• Chemical composition: Cu ≥ 99.99%; impurities (Pb, Ni, Sn, Ag, Sb, As, Bi, Te, Se, Fe, S, P) each ≤ 0.0005% – 0.002% (ASTM B115 / LME Grade A standard)

• Purity level: 99.99% (4N) minimum

• Physical characteristics: Flat, trapezoidal or rectangular plates; thickness approx. 10–15 mm; weight per sheet 50–150 kg; clean, burnished surface; no nodules or porosity

• Packaging options: Aluminium strapped pallets (1–2 MT each), shrink-wrapped, or container-loaded bulk stacks

• Shelf life: Indefinite under dry, covered storage; no degradation in conductivity or purity when protected from oxidation

Core Industrial Applications

• Wire & cable manufacturing: Drawn into ultra-fine wires for automotive, renewable energy (EV, solar), and telecom cabling – superior ductility reduces breakage rates by ~30% versus standard cathodes.

• Brass and alloy production: Base metal for CuZn, CuSn, CuNi alloys – low impurity profile eliminates downstream refining steps.

• Electrical components: Busbars, transformers, motor windings – 99.99% purity delivers consistent conductivity with minimal Joule heating.

• Semiconductor and electronics: Sputtering targets and lead frames – trace-level contaminant control meets SEMI standards.

• Industrial advantage: Lower melting energy and higher first-pass yield (99.2% vs. 97.5% for lower grades) directly reduce COGS.

Competitive Advantages

• Quality consistency: Every batch tested via optical emission spectrometry and LME-approved assay with traceable certificates.

• Supply reliability: Direct offtake from ISO 9001:2024 smelters with 12-month take-or-pay contracts available.

• Logistics capability: 3-week lead time to any major port (Rotterdam, Shanghai, Busan, Baltimore) via container or breakbulk.

• Price competitiveness: Pricing at LME cash settlement minus $25–$45/MT for steady volumes >5,000 MT/month.

• Sustainability: 95% recycled-content compatible; Scope 3 emissions data provided per GLEC framework.

Commercial & Supply Information

• Minimum order quantity (MOQ): BULK 20 MT (one standard LCL container or palletised lot)

• Loading capacity: 20 MT per 20-foot dry container (stowed with 2,000–2,200 kg per pallet, 10–11 pallets per container)
