Refined Nickel (99%+)

Description

1. Product Overview
Refined Nickel (99%+ min) is a high-purity, fully alloyed base metal produced via advanced electro-winning or carbonyl refining processes. Its primary industrial use lies in stainless steel and specialty alloy manufacturing, battery cathode precursors (NMC/NCA), and high-temperature corrosion-resistant coatings. The key value proposition is exceptional chemical consistency, ultra-low impurity profiles (particularly for sulfur, iron, and cobalt), and predictable electro-chemical performance. In a market increasingly defined by EV supply chains and high-grade austenitic steel demand, this material serves as a strategic bottleneck input—enabling customers to achieve tighter production tolerances and higher final-product yield.

2. Key Specifications & Technical Characteristics

• Chemical composition: Ni 99.0% min; typical 99.2–99.6%; impurities controlled: Fe ≤ 0.08%, Co ≤ 0.05%, Cu ≤ 0.02%, C ≤ 0.03%, S ≤ 0.005%, P ≤ 0.002%

• Purity / Grade: LME Grade A equivalent; non-prime primary nickel (suitable for melting, alloying, and plating)

• Physical characteristics: Electrolytic cathodes (cut squares / full plates) or briquettes / rondelles; color: silver-bright metallic; particle size: 10–50 mm (cathode chips) or 3–15 mm (nickel crowns)

• Density: 8.9 g/cm³ (true); bulk density approx. 3.5–4.2 t/m³ (depending on form)

• Packaging options: 1 MT steel-banded pallets; 500 kg drummed boxes; bulk container liner (15–20 MT per 20’ container)

• Shelf life: Indefinite under dry, indoor storage (no oxidation risk beyond superficial tarnish)

3. Core Industrial Applications

• Stainless steel (300 series – austenitic): Used as a primary austenite stabilizer and corrosion resistance enhancer. Outperforms lower-purity ferronickel or nickel pig iron by reducing slag formation, lowering rework rates, and improving surface finish on cold-rolled coil.

• Battery cathode active materials (NMC 811, 622): Dissolved into nickel sulfate for precursor synthesis. Our 99%+ refined nickel provides tighter batch-to-batch consistency in metal ion concentration, directly improving battery cycle life and reducing costly downstream filtration steps.

• High-temperature alloys (Inconel, Hastelloy, Monel): Critical for creep strength and oxidation resistance up to 1100°C. Superior purity minimizes micro-segregation during vacuum induction melting (VIM), a key advantage over secondary nickel sources.

• Electroplating (sulfamate and Watt’s baths): Nickel crowns (S-rounds) allow uniform dissolution and fewer in-process anode changes, reducing downtime by ~15% vs. standard electrolytic squares.

4. Competitive Advantages

• Quality consistency: Statistical process control (SPC) on every production lot; typical Cpk > 1.33 for all major impurity elements — certified with LME/SGS CoA.

• Supply reliability: Dual-feed from primary refining (hydromet + electrolytic) and near-prime remelting; on-hand buffer stock across Rotterdam, Busan, and Houston hubs.

• Logistics capability: Door-to-door delivery with barge, rail, and containerized shipping; demurrage risk mitigation via bonded warehousing adjacent to major industrial zones.

• Price competitiveness: Long-term fixed-price contracts + index-linked LME-based pricing with +/- $50/MT premium to cash settlement; volume discounts transparently tiered.

• Sustainability & documentation: Low-carbon certification (Scope 1+2 ≤ 8 t CO₂e / t Ni); full traceability from mine to gate; available with responsible sourcing declarations (OECD alignment).

• Technical support: In-house metallurgy team to validate melt recipes, dissolution rates, and final alloy mechanical properties — typically responding <24h for B2B inquiries.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): BULK 20 MT (one standard lot for LME delivery or contract fulfillment)

• Loading capacity (MT per container):

  • 20 ft dry container: 20–22 MT (bulk liner or palletized)

  • 40 ft HC container: 22–24 MT (weight-limited, not volume-limited)

  • Break-bulk vessel: ≥ 200 MT per hold
