1. Introduction
In a major development just 24 hours ago, the U.S. Department of Commerce announced new export controls on high-purity titanium powder used in aerospace and defense additive manufacturing, citing national security concerns. This move has sent ripples through the global supply chain, reigniting interest in titanium powder sourcing, pricing, and alternatives. Whether you’re an engineer, researcher, or procurement specialist, understanding titanium powder—from its basic forms to advanced applications—is more critical than ever.
2. What Is Titanium Powder?
Titanium powder, often referred to as Ti powder, is a fine particulate form of titanium metal. It can be produced in various morphologies—spherical, irregular, or flake-like—and purities, ranging from commercially pure grades to complex alloys. Unlike bulk titanium, powder form enables advanced manufacturing techniques like additive manufacturing (3D printing), metal injection molding, and thermal spraying.
3. How Is Titanium Powder Made?
Two primary methods dominate titanium powder production: gas atomization and the hydride-dehydride (HDH) process. Gas atomized titanium powder yields spherical particles ideal for 3D printing due to excellent flowability. HDH titanium powder, on the other hand, produces irregular, angular particles better suited for pressing and sintering. Other niche methods include plasma rotating electrode process (PREP) and electrolytic reduction.
4. Common Types of Titanium Powder
- Pure titanium powder: Used in chemical processing and medical implants where biocompatibility is key.
- Ti6Al4V powder (also called Ti64 powder): The most widely used titanium alloy powder, especially in aerospace and medical 3D printing.
- TiH2 powder: Titanium hydride, often used as a foaming agent or precursor in powder metallurgy.
- Titanium nitride powder and titanium carbide powder: Hard, wear-resistant ceramics used in coatings and cutting tools.
- Titanium diboride powder (TiB2 powder) and titanium boride powder: Ultra-high-melting-point materials for refractory applications.
- TiO2 nano powder: Not a metal powder, but a white pigment used in sunscreens, paints, and cosmetics—distinct from metallic titanium powder.
- Titanium flash powder: A pyrotechnic mixture (not pure titanium) used in special effects; highly reactive and regulated.
- Burnt titanium powder coat: A misnomer—titanium itself isn’t typically powder coated due to its oxide layer; this phrase may refer to surface-treated parts.
- Titanium coated diamond powder: Used in precision grinding and polishing applications.
5. Titanium Powder Uses
Titanium powder uses span multiple high-tech industries. In aerospace, it’s essential for lightweight, high-strength jet engine and airframe components. The medical field leverages titanium metal powder for custom implants via 3D printing. Automotive, energy, and defense sectors use it for wear-resistant parts and armor. Additive manufacturing has become the fastest-growing application, driving demand for spherical titanium powder with tight particle size distribution.
6. Titanium Powder for 3D Printing
Titanium powder for 3D printing must meet strict standards: high purity, spherical morphology, and controlled particle size (typically 15–45 microns). Ti6Al4V powder is the go-to alloy, offering an excellent strength-to-weight ratio and corrosion resistance. As 3D printing scales, so does demand—making titanium powder for 3D printing price a key consideration. Current titanium 3D printing powder prices range from $300 to $600 per kg, depending on grade, supplier, and volume.
7. Titanium Powder Pricing and Suppliers
Titanium powder price per kg varies widely based on form, purity, and production method. Pure titanium powder may cost $150–$300/kg, while high-spec Ti6Al4V powder for additive manufacturing can exceed $500/kg. Factors like global supply chain constraints, energy costs, and export regulations heavily influence titanium metal powder price. Reputable titanium powder suppliers include international players like VSMPO-AVISMA, Carpenter Technology, and Sandvik. When looking to buy titanium powder, always verify certifications for oxygen content, particle size, and flowability.
8. Related Advanced Metal Powders
While titanium powder dominates lightweight applications, other refractory metal powders serve complementary roles. Molybdenum powder (including moly powder, MoS2 powder, and TZM powder) is prized for high-temperature stability. Tungsten powder—available as pure tungsten powder, tungsten carbide powder, or spherical tungsten powder—is used in radiation shielding, cutting tools, and wear parts. Companies like Global Tungsten & Powders Corporation supply high-density tungsten powder for defense and industrial uses. Though distinct from titanium, these materials often appear in the same supply ecosystems, especially in additive manufacturing and powder metallurgy.
9. Safety and Handling
Fine titanium dust can be flammable or even pyrophoric under certain conditions—especially in nanopowder or irregular forms. Proper handling in inert atmospheres (argon or nitrogen) is essential. Always follow OSHA and supplier safety guidelines when storing or processing titanium powder.
10. Conclusion
Titanium powder is a cornerstone of modern advanced manufacturing, with expanding roles in 3D printing, aerospace, and medicine. Understanding its types—from pure titanium powder to Ti6Al4V powder—and staying informed on titanium powder price trends and reliable suppliers is crucial for industry professionals. As global regulations evolve and additive manufacturing grows, titanium powder will remain a strategic material with high value and high demand.
