Niobium ingots are dense blocks formed by melting and casting high-purity niobium metal. They possess extremely high chemical stability, excellent superconductivity, and high-temperature resistance, making them a key foundational material for high-end industry and scientific research.
Core Parameters and Features
1. Ultra-High Purity:
Niobium content ≥99.99% (4N purity), significantly reducing the interference of impurity elements (such as Ta, Fe, Ni, W, and Mo) on the material's conductivity, mechanical properties, and smelted alloy composition, meeting the requirements of semiconductor-grade applications.
2. Large Size:
Maximum Diameter: 400 mm (D400mm)
Maximum Single Ingot Weight: 2 metric tons (2T)
Meets the raw material size requirements of large-scale industrial production, reduces processing losses, and improves efficiency.
3. Professional Protective Packaging:
Inner Protection: The surface of the forged ingot is tightly wrapped with high-strength stretch film to isolate air and moisture, preventing surface oxidation and physical damage during transportation and storage.
Buffer Layer: High-quality pearl cotton is padded between the ingot and the wooden box to provide effective shock absorption and protect against transportation shock. Outer Packaging: Reinforced wooden boxes that meet international export standards ensure safe, moisture-resistant, and impact-resistant long-distance sea or land transportation.
4. Core Application Areas:
Semiconductor Manufacturing: Serves as a core raw material for ultra-high-purity sputtering targets used for depositing critical thin film layers; used as a high-temperature, corrosion-resistant crucible or component material in single-crystal silicon growth equipment.
High-Performance Alloy Melting: Serves as a core alloying element, significantly enhancing the high-temperature strength, corrosion resistance, and low-temperature superconductivity of nickel-based/titanium-based superalloys (used in aircraft engine turbine blades and rocket nozzles), specialty steels (high-strength low-alloy steels and stainless steels), and superconducting alloys (such as NbTi and Nb₃Sn).
