Smelted niobium

Smelted niobium is metallic niobium purified through a high-temperature reduction process. It exhibits a high melting point, corrosion resistance, and excellent low-temperature toughness, making it a core raw material for high-end alloy manufacturing.

Key Characteristics and Technical Parameters
▸Purity
Purity is ≥99.9% (3N grade), with key impurities (such as Ta, Fe, and Si) strictly controlled at the ppm level to ensure material consistency.
▸Dimensions and Weight
Customizable dimensions (typical range: diameter 10–200mm, length ≤1,500mm), supporting non-standard ingot, bar, or pellet forms.
Unit weight can be customized upon request (up to 5 tons), meeting batch melting or laboratory-scale trace needs.
▸Industrial-Grade Packaging
Double-layered, anti-oxidation treatment: an inner vacuum-sealed polyethylene bag and an outer argon-filled galvanized steel drum (standard 50kg/drum).
Packaging complies with Chuangrun's CR-Pack standard, with a weather-resistant label on the drum containing the batch number, composition analysis, and ISO 9001 certification mark.
▸Core Applications
High-temperature alloy smelting: As a strengthening additive in Nb-Ti and Nb-Zr superconducting alloy matrices, or IN718 nickel-based alloys, it improves the heat resistance of aircraft engine components.
Specialty steel smelting: Adding 0.1–1.5% niobium refines austenite grains and enhances creep resistance in nuclear power pipelines and petrochemical reactors.
