- Product Introduction
Product Overview
Our nickel ingots are primary refining materials produced via electrolytic deposition. They are designed as an elemental grain addition for stainless steel metallurgy, nickel-based superalloys, surface electroplating, and chemical synthesis for EV battery precursors (NiSO₄).
Unlike scrap-recycled or blended-grade alternatives, these primary ingots feature stable chemistry and low secondary element profiles, supporting predictable melting behavior and minimizing yield loss during induction furnace operations.
Purity Range: 99.5% to 99.99% elemental Ni (including Co).
Impurity Control: Strict limits on sulfur, carbon, and low-melting-point elements to prevent thermal cracking in downstream alloys.
Supply Capacity: 50,000 Metric Tons annually.
Technical Specifications & Chemical Composition
All batches comply with the chemical requirements of ASTM B39 or equivalent global standards.

Primary Applications
Stainless Steel
Core alloying component for 300-series (e.g., 304, 316) and duplex grades to establish the austenitic phase and improve corrosion resistance.
Superalloys
Base matrix element for high-temperature nickel alloys used in gas turbines and industrial aerospace engineering.
Battery Chemistry
High-purity feedstock for chemical dissolution into battery-grade nickel sulfate, a precursor for lithium-ion cathode active materials (NCM/NCA).
Electroplating
Used as high-purity sacrificial anodes for uniform electrodeposited protective layers.
