Overview of Niobium High Purity NbTi Alloy Niobium Titanium Sputtering Target Supply s
Niobium, often found in conjunction with tantalum minerals, is primarily extracted as a byproduct of tin and tantalum mining. Its chief ores include pyrochlore and columbite. Once refined, niobium becomes highly versatile, finding application in alloys, superconductors, and various high-tech materials.
Feature of Niobium High Purity NbTi Alloy Niobium Titanium Sputtering Target Supply s
-
Superior Strength and Lightness: When added to steel in small quantities (typically less than 1%), niobium significantly enhances the strength and toughness of the alloy while reducing its weight, making it ideal for aerospace and automotive applications.
-
Corrosion Resistance: Like tantalum, niobium forms a passive oxide layer that protects it from corrosion, making niobium-based alloys suitable for use in harsh environments.
-
Superconductivity: Niobium exhibits excellent superconducting properties when cooled below its critical temperature of about 9.2 K (-264°C or -443°F). This property makes it the primary material for superconducting magnets used in MRI scanners and particle accelerators.
-
Magnetic Properties: Niobium is paramagnetic at room temperature but becomes strongly diamagnetic when cooled, meaning it repels magnetic fields. This characteristic is exploited in certain specialized applications.
-
Ease of Fabrication: Despite its strength, niobium is easily formed, welded, and machined, facilitating its use in complex engineering designs.

Parameters of Niobium High Purity NbTi Alloy Niobium Titanium Sputtering Target Supply s
Niobium-Titanium (NbTi) alloy is a popular material used in various applications, especially in superconducting magnets and electronic devices due to its high critical temperature for superconductivity and good mechanical properties. A high purity Niobium Titanium (NbTi) sputtering target typically has the following specifications:
1. Composition: The typical composition of high purity NbTi alloy is around 90% Nb (Niobium) and 10% Ti (Titanium), although exact percentages may vary depending on the specific grade.
2. Purity: The purity level is crucial for achieving optimal performance. A high purity target, usually greater than 99.9%, ensures minimal impurities that could affect the quality of the deposited material.
3. Grain Size: The grain size of the target affects the uniformity of the deposited film. Smaller grain sizes lead to smoother surfaces and better crystal structure. For sputtering targets, grain sizes can range from sub-micron to a few microns.
4. Shape and Size: Targets are commonly available in cylindrical or rectangular shapes and can range in diameter from a few centimeters to several meters, depending on the application and the sputtering system’s requirements.
5. Thickness: The target thickness can vary, typically from a few millimeters to a few centimeters, but it should be thick enough to withstand the sputtering process without significant erosion during operation.
6. Surface Finish: The surface finish should be smooth and free of defects to ensure efficient sputtering and minimize particle contamination.
7. Thermal Conductivity: High purity NbTi alloy has excellent thermal conductivity, which helps maintain a stable substrate temperature during deposition.
8. Hardness: The hardness of the target determines its resistance to wear during the sputtering process. A harder target can last longer before needing replacement.
9. Melting Point: The melting point of pure Nb is around 2,467°C (4,475°F), while for NbTi alloy, it will be slightly lower due to the presence of titanium.
10. Magnetic Properties: As a superconductor, NbTi alloy exhibits Type II superconductivity with a critical magnetic field (Hc) and temperature (Tc) suitable for many applications.
When sourcing a Niobium-Titanium sputtering target, it’s essential to consult the supplier for specific details tailored to your requirements, as not all grades and parameters are universally applicable.
