Features of EB Spherical Shape Titanium Ti6Al4V Powder TC4 Powder for 3D Printing
Physical Characteristics
Particle Size: Ranging from nanometers to hundreds of micrometers, the size distribution significantly influences the powder’s flowability, packing density, and sintering behavior.
Shape: Particles can be spherical, irregular, flake-like, or dendritic, each shape affecting the final product’s mechanical properties and surface finish.
Purity: Depending on the production method, metal powders can achieve high levels of purity, critical for applications like electronics and aerospace where impurities can degrade performance.
Density: While less dense than their solid counterparts due to the presence of air between particles, metal powders can be densely packed during processing to approach the density of the solid metal.
Chemical Properties
Reactivity: Some metal powders, particularly aluminum and titanium, are highly reactive with air and moisture, necessitating careful handling and storage under inert atmospheres or vacuum.
Oxidation: Exposure to air can lead to surface oxidation, forming a passive layer that affects sintering and other processes. This can be managed through surface treatment or use of protective atmospheres.

Title: Technical Specifications and Parameters for Spherical Titanium Ti6Al4V and TC4 Powders for 3D Printing
Introduction:
Spherical titanium alloys, specifically Ti6Al4V (Titanium Aluminum Vanadium) and TC4 (Titanium Carbonitride), are widely used in 3D printing due to their exceptional mechanical properties and versatility. This brief overview will delve into the key parameters that define these powders for successful 3D printing applications without any specific formatting.
1. Material Properties:
– Ti6Al4V: A widely recognized aerospace-grade material, Ti6Al4V boasts high strength, corrosion resistance, and biocompatibility. It exhibits excellent mechanical properties, including high yield strength (900 MPa), ultimate tensile strength (1100 MPa), and fatigue resistance, making it suitable for demanding applications such as aerospace, medical implants, and automotive components.
– TC4: A lightweight, high-strength alternative, TC4 is known for its high melting point, low thermal expansion coefficient, and excellent wear resistance. It is often used in high-speed cutting tools and aerospace components where weight reduction is crucial.
2. Particle Size Distribution (PSD):
– Both powders feature a narrow PSD to ensure consistent layer adhesion during 3D printing. A typical range is 20-63 micron for Ti6Al4V and 5-30 micron for TC4, allowing for precise control over print resolution and surface finish.
3. Particle Shape:
– The spherical shape of the powders ensures better flowability, reducing the risk of clogging during the printing process. Spherical particles have a lower surface area to volume ratio, promoting more efficient bonding during fusion and minimizing porosity.
4. Chemical Purity:
– High purity levels are essential for achieving reliable prints. Ti6Al4V powders typically have a purity of 99.5% or higher, while TC4 powders usually have a purity of 99.8%. Impurities can affect print quality and part integrity.
5. Particle Size Homogeneity:
– A uniform particle size distribution is crucial for consistent print quality. Both powders undergo rigorous sieving processes to achieve this, ensuring minimal variation in particle size across the batch.
6. Melting Behavior:
– Ti6Al4V has a relatively low sintering temperature compared to other titanium alloys, typically around 1250°C to 1400°C, while TC4 melts at around 2700°C. Knowledge of these temperatures is vital for setting optimal print parameters.
7. Print Parameters:
– For Ti6Al4V, common printing parameters include: layer height (10-50 microns), print speed (0.1-1 mm/s), and temperature (400-600°C for powder bed fusion). For TC4, the temperature may be higher, around 3000-3200°C, due to its elevated melting point.
8. Post-Processing:
– After printing, both materials require proper post-processing, such as heat treatment and machining, to achieve the desired mechanical properties. Ti6Al4V may need stress-relief annealing, while TC4 may require cooling rates to prevent grain growth.
In conclusion, the success of 3D printed parts using Ti6Al4V and TC4 spherical powders depends on understanding and optimizing these parameters. By considering material properties, particle characteristics, and print settings, engineers can create intricate and functional components tailored to specific application requirements.
