Chemical Properties
Corrosion Resistance: Excellent inertness in most acid and alkaline media; corrodes only in high-temperature concentrated acids or strong oxidizing agents
Oxidation Behavior: Forms dense niobium oxide (Nb₂O₅) protective layer at high temperatures, enhancing oxidation resistance up to 800°C
Low Solubility: Minimal solubility in common alloys (iron, nickel, copper), suitable for corrosion-resistant linings or isolation materials
Chemical Purity: Main impurity content ≤0.2% in commercial niobium foil, primarily Ti, Zr, Mo, compliant with ASTM B393-05 and other international standards
Mechanical Properties
High Strength & Ductility: Room temperature tensile strength up to 550 MPa, yield strength 240 MPa, elongation ≥30%, combining high strength with excellent plasticity
High-Temperature Strength Retention: Maintains significant strength in vacuum or inert atmospheres above 1000°C, suitable for high-temperature structural components
Hardness: Approximately 110-180 HV, depending on heat treatment and thickness
Welding & Processing: Niobium foil facilitates hot rolling, cold rolling, punching, laser cutting, and welding, with precision processing achievable under inert gas protection

Selection & Usage Guidelines
Purity & Specifications: Select 99.8%-99.99% purity based on application environment; thickness and width should meet mechanical strength and thermal conduction requirements
Surface Treatment: For high-temperature or strong acid/alkaline environments, surface polishing or passivation treatment enhances oxide layer density
Storage Conditions: Recommend vacuum packaging or inert gas (argon, nitrogen) environment storage to prevent moisture-induced oxidation
Processing Techniques: Annealing required after hot rolling to restore ductility; control heat input during stamping and laser cutting to avoid stress concentration
Safety & Environmental: Niobium metal is non-toxic, but high-temperature processing generates metal vapors requiring proper ventilation and protective equipment
