Features of TC4-Ti6242 Ti6Al4V AMS 4998 Spherical titanium and titanium alloy powder for 3D print
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.

Parameters of TC4-Ti6242 Ti6Al4V AMS 4998 Spherical titanium and titanium alloy powder for 3D print
TC4-Ti6242 and Ti6Al4V are two grades of titanium alloys commonly used in additive manufacturing, specifically for 3D printing applications. These materials exhibit exceptional strength, durability, and biocompatibility, making them popular choices for aerospace, automotive, medical, and various engineering industries.
TC4 (Titanium Grade 4) is an alpha-beta titanium alloy, characterized by its high strength-to-weight ratio and excellent mechanical properties. It possesses good formability, corrosion resistance, and fatigue life, making it suitable for complex geometries that require lightweight yet robust components. The melting point of TC4 is approximately 1,725°C (3,140°F), which allows for efficient printing without excessive heat distortion.
Ti6Al4V, on the other hand, is a more versatile and widely used titanium alloy, known as INCONEL 6242 in some regions. It is a beta-type titanium alloy with a higher percentage of aluminum and vanadium, which imparts greater strength, hardness, and wear resistance compared to TC4. Ti6Al4V also boasts excellent biocompatibility, making it ideal for medical implants and orthopedic applications. Its melting point is around 1,670°C (3,038°F). This alloy’s balance of properties, including creep resistance and corrosion resistance, makes it a go-to choice for demanding applications like aerospace components.
AMS 4998 is a specific standard for additive manufacturing processes, developed by ASTM International, which outlines guidelines for the production and use of titanium and titanium alloy powders, such as TC4 and Ti6Al4V. This standard ensures consistent quality, dimensional accuracy, and process control across different manufacturers, enabling reliable and repeatable 3D printed parts.
The spherical titanium and titanium alloy powders for 3D printing are specifically formulated for use in Directed Energy Deposition (DED) or Selective Laser Melting (SLM) processes, where they are melted layer by layer to create solid structures. The spherical shape of the particles promotes better flowability, minimizing voids and ensuring a homogeneous distribution within the build. Additionally, these powders often have a narrow size distribution, enhancing the accuracy of the printed features and reducing post-processing requirements.
In terms of parameters, the powder characteristics include particle size, purity, morphology, and chemical composition. The ideal particle size for 3D printing depends on the printer’s nozzle diameter and the desired resolution, typically ranging from 15 to 50 microns. Purity is crucial for achieving optimal part properties, with impurities potentially affecting strength and corrosion resistance. The morphology, or the surface roughness of the particles, can impact print adhesion and part finish. Lastly, the exact chemical composition, such as the ratios of titanium, aluminum, vanadium, and other elements, must match the targeted alloy properties.
In conclusion, TC4-Ti6242 Ti6Al4V powders are high-performance materials for 3D printing, offering unique combinations of strength, durability, and biocompatibility. Adhering to standards like AMS 4998 ensures consistent quality and enables the creation of intricate, functional components across various industries. By optimizing the powder parameters, engineers can unlock the full potential of these alloys in the realm of additive manufacturing.
