Spherical C103 alloy powder is an alloy material with niobium (Nb) as its main matrix. Due to its high-temperature resistance and good stability, it is used in some special applications.
What is Spherical C103 Alloy Powder?
Spherical C103 alloy is an alloy with niobium (Nb) as its main element, typically containing elements such as hafnium (Hf) and titanium (Ti). This alloy maintains good mechanical strength and corrosion resistance even at high temperatures, making it suitable for industrial applications in extreme environments.
Spherical C103 alloy powder refers to metal powder with a spherical particle shape produced through special processes (such as plasma spinning electrode method or gas atomization method). This shape is beneficial for improving the material’s flowability and filling density, making it suitable for additive manufacturing, thermal spraying, powder metallurgy, and other processes.
Specifications
Generally, the specifications of metal powders vary depending on customer needs and application scenarios. Below are some common specification types suitable for different industrial requirements:
– Particle Size Distribution: This is one of the most critical characteristics of the powder. Common particle size ranges include 15-45 μm, 45-75 μm, and 75-150 μm. Fine powders (e.g., 15-45 μm) are suitable for precision manufacturing and additive manufacturing, while coarser powders (e.g., 75-150 μm) are often used in thermal spraying or welding processes.
– Chemical Composition: The typical composition of C103 alloy is niobium-based (approximately 89% or more), supplemented with hafnium (approximately 10%) and titanium (approximately 1%). Other impurity elements such as oxygen and nitrogen must be strictly controlled at low levels to ensure the stability of material properties.
| Components of C103 (Nb-10Hf-1Ti) | |||||
|---|---|---|---|---|---|
| Nb | Hf | Ti | Zr | Ta | W |
| Bal | 9–11% | 0.7–1.3% | 0.7% Max | 0.5% Max | 0.5% Max |
-Sphericity: High-quality spherical powder requires high particle roundness and a smooth surface, which improves powder flowability and spreading effect.
-Loose packing density: Spherical C103 alloy powder typically has a high loose packing density, reaching 4.0-5.0 g/cm³, with good flowability. Higher density means the powder is easier to compact during processing.
These parameters can be adjusted according to the user’s actual needs to meet the requirements of different application scenarios.
Applications of Spherical C103 alloy powder
Spherical C103 alloy powder is widely used in aerospace, additive manufacturing, and nuclear industries due to its high-temperature resistance and oxidation resistance.
Aerospace: Used in critical components of rocket engines, such as nozzles, throat liners, and nozzle expander sections, operating at temperatures of 1400–1700 °C, relying on its excellent high-temperature strength and creep resistance.
Aircraft Engines/Military Equipment: Used in ultra-high temperature heat shields, infrared protection structures, and high-temperature reflectors, requiring heat-resistant and corrosion-resistant thin-walled or complex components.
Additive Manufacturing (3D Printing): Spherical powder is suitable for SLM, EBM, DED, and other processes for printing complex high-temperature parts. Its good powder flowability and stable forming properties make it suitable for aerospace and special equipment requirements.
Nuclear Industry and Extreme Environment Equipment: Used in high-temperature shielding components, thermal structural components, and components for irradiated environments, leveraging the high-temperature stability and radiation resistance of niobium-based alloys.
Note: specific applications require consideration of actual circumstances and professional guidance.
How to selection Spherical C103 Powder and Usage?
When selecting spherical C103 alloy powder, users need to consider specifications based on specific application requirements. For example, additive manufacturing processes require uniform powder particle size and low impurity content to ensure the quality of printed parts; while thermal spraying applications place greater emphasis on powder flowability and density.
It is recommended to perform particle size testing and composition analysis before use to ensure compliance with expected standards. During use, relevant safety regulations must be followed, such as wearing protective equipment and avoiding inhalation of powder or direct skin contact.
Store in a sealed, dry environment to prevent oxidation or moisture absorption.
In general, c103 spherical powder is a high-performance material with a variety of commonly used specifications, suitable for multiple fields from aerospace to the nuclear industry.
