Overview of Spherical 3D printing pure titanium alloy powder TC4/Ti6Al4V titanium powder
Spherical 3D printing pure titanium alloy powder TC4/Ti6Al4V titanium powder comprises a broad category of finely divided, solid particles derived from various metals or metal alloys. These powders exhibit unique characteristics that make them indispensable in modern manufacturing and advanced technologies.
Key Characteristics of Spherical 3D printing pure titanium alloy powder TC4/Ti6Al4V titanium powder
-
Particle Size and Distribution: The size and uniformity of particles significantly influence flowability, packing density, and the final product’s mechanical and physical properties. Finer powders generally offer a larger surface area, which is beneficial for reactions and sintering but may also increase aggregation.
-
Composition: Metal powders can be elemental (pure metal) or alloyed, combining two or more metals to achieve desired properties such as enhanced strength, corrosion resistance, or electrical conductivity.
-
Shape: Particle shapes range from spherical to irregular or flake-like. Spherical powders provide better flowability and packing, while flake-shaped powders are suited for coatings and electronic applications due to their unique orientation and surface area.
-
Purity: Depending on the application, metal powders can be highly purified to remove impurities, critical for uses in electronics, aerospace, and medical devices where contamination could compromise performance.

Parameters of Spherical 3D printing pure titanium alloy powder TC4/Ti6Al4V titanium powder
The spherical 3D printing of pure titanium alloys, specifically TC4 (Titanium grade 5) and Ti6Al4V (Ti-6Al-4V), involves powders with specific characteristics to ensure high-quality prints. Here are some key parameters for these titanium powders:
1. Particle Size Distribution (PSD):
– Generally, the particles are in the submicron range, often between 15-63 microns, for better flowability and sinterability during 3D printing.
– A narrow PSD ensures consistent layer adhesion and print quality.
2. Sphericity:
– High sphericity is crucial for achieving good bed adhesion and minimizing porosity. Spherical particles are easier to handle and result in fewer defects during printing.
3. Chemical Composition:
– Pure TC4: 90-94% Ti, 6-8% Al, and very low (<0.1%) impurities.
– Ti6Al4V: 90-94% Ti, 5-6% Al, and 3-4% V, with trace amounts of other elements like iron, oxygen, and carbon.
4. Density:
– Both TC4 and Ti6Al4V have high densities, typically around 4.43 g/cm³ for TC4 and 4.51 g/cm³ for Ti6Al4V, which is essential for maintaining structural integrity in printed parts.
5. Melting Point:
– TC4: ≈1670°C (3040°F)
– Ti6Al4V: ≈1660°C (3020°F)
– These high melting points ensure that the printed parts can withstand high temperatures during post-processing.
6. Heat Conductivity:
– Good thermal conductivity is important for dissipation of heat during printing and maintaining part accuracy. Titanium alloys are known for their high thermal conductivity.
7. Fluidity and Adhesion:
– The powders should have good fluidity to allow for easy spreading during extrusion and form a strong bond with the substrate or previous layers.
8. Oxygen Absorption:
– Low oxygen absorption is desirable to prevent degradation and maintain material properties.
9. Specific Surface Area (SSA):
– Higher SSA can enhance surface finish and bonding in the printed parts.
These parameters can vary slightly depending on the manufacturer, but they provide a general overview of the typical specifications for spherical 3D printing pure titanium alloys like TC4 and Ti6Al4V. Always consult the supplier's specifications for the most accurate information.
