Titanium powder producers offer specialty fine particle size metal feedstocks enabling fabrication of aerospace, medical, automotive, and consumer components via additive manufacturing as well as powder metallurgy consolidation. This article compares major global titanium metal powder suppliers across characteristics like location, grades, production capacity, prices, and quality certifications.

Overview of titanium metal powder suppliers

Pure titanium powders containing over 99% titanium have excellent strength-to-weight ratios, corrosion resistance, biocompatibility, high melting point, and hardness values making them suitable for demanding applications across industries.

Alloying elements like aluminum, vanadium, molybdenum, zirconium, tin, niobium, tantalum, and silicon are added to further augment properties for niche performance requirements.

Common titanium powder grades include:

• CP (komerčně čistý) titan
• Ti-6Al-4V – Aerospace grade
• Ti-6Al-7Nb – Biomedical grade
• Ti-55531 – High temperature alloy
• Ti-1023 – Heavy metal alloy

These powders spanning 1 to 150 microns size ranges are used across:

• Aditivní výroba
• Vstřikování kovů
• Press and sinter near-net shape fabrication
• Powder forged components
• Tepelně stříkané povlaky
• Pyrotechnics and ordnance
• Powder metallurgy consumables

Top 10 Titanium Powder Manufacturers

Leading global producers of CP titanium, Ti-6-4, and other titanium alloy powders are concentrated across the Americas, Europe, China, India and Japan.

These prominent suppliers offer most common titanium grades but also develop custom alloys and particle characteristics to meet user application requirements.

USA Titanium Powder Manufacturers

The United States produces over 15% of global titanium feedstock materials leveraging domestic aerospace, medical, defense, and automotive sector demand. Aside from large established corporations, a cottage industry of small and mid-sized North American vendors also exists.

Major USA firms

Other USA titanium suppliers include Strem Chemicals, Edge Metal, Commercial Metals Company, Nu-Tek Innovations, Metraco, and several metal 3D printing service bureaus with powder inventory.

Pricing estimate: $50-500 za kg based on purity, chemistry, particle characteristics, distribution consistency, volumes purchased and available supply chain margins.

Chinese Titanium Powder Manufacturers

China has a rapidly growing domestic aerospace sector coupled with strong export demands which propelled several titanium powder producers to emerge over the past decade.

Major Chinese companies

Additional players are emerging as China ramps investment in metal AM powder capacity to serve growing domestic demand. Joint ventures with European and American firms are also underway providing technology transfers.

Pricing estimate: $30-150 per kg – Over 50% lower than US and EU prices for standard CP titanium and Ti alloy options.

European Titanium Powder Companies

Europe’s strong aerospace legacy combined with pioneering efforts in metal additive techniques supported a vibrant ecosystem of regional titanium powder manufacturers.

Key European firms

Additional companies like LPW Technology, Indo-US MIM Tec Pvt., Supra Alloys Inc., and PyroGenesis offer more regional targets or custom titanium development services.

Pricing estimate: $70-300 per kg for small batch CP titanium or Ti-6Al-4V.

Critical Supplier Selection Criteria

Choosing suitable titanium powder sources depends on several aspects:

Technical factors

• Chemistry – Grade and composition within allowed elemental limits
• Particle size distribution consistency
• Morphology – Sphericity, satellite fractions, texture
• Apparent/tap density uniformity
• Flow rate, moisture limits, layer uniformity

Commercial considerations

• Price per kg – Dictated by tier, purity and logistics
• Minimum order quantities
• Custom alloy flexibility
• Lead times and availability
• Packaging and shelf life guarantees

Company qualifications

• Time in business and production capacity
• Quality certifications – ISO 9001, AS9100, etc.
• Testing capabilities and reports
• Safety, sustainability and compliance record

Application demands

• Printer, powder bed, spray compatibility
• Part performance requirements
• Mechanical properties targets
• Testing correlations to properties

Carefully qualifying powder against credibility, cost, consistency and suitability metrics minimizes downstream manufacturing risks.

Industry Quality Standards

Titanium powders for commercial aerospace, medical, automotive and regulated uses require certification demonstrating compliance to governing specifications.

Common test methods include:

• Chemical analysis – ICP, GDMS, Combustion
• Metallography – Microstructure
• Particle size distribution – Laser diffraction
• Apparent/tap density – Hall flowmeter
• Powder morphology – SEM imaging

Reputable global titanium powder suppliers provide lot traceability and test reports documenting quality adherence as well as scope for customer witnessing or split sampling.

FAQ

Q: How is titanium powder manufactured?

A: Most large scale titanium powder derives from sponge fines or hydride-dehydride (HDH) methods while small batch specialized powders employ plasma atomization or electrolysis techniques. Each enables tailored powder size distributions, shapes and purity levels.

Q: What are the main differences between Ti-6Al-4V grades from different suppliers?

A: Minor variations in impurity limits, microstructure from thermal history, distribution percentiles, morphologies from different atomization mediums, available size ranges and testing breadth account for considerable grade variability between producers claiming Ti-6-4 chemistry. Understanding subtler differences is vital.

Q: How much does titanium powder for 3D printing cost?

A: Expect to pay $90-220 per kg for common grades like CP Ti Grade 2 and Ti-6Al-4V ELI intended for additive manufacturing over standard industrial varieties. Processing method, distribution yield, order volume, regional logistics and downstream margins differentiate pricing.

Q: What companies offer titanium powder recycling services?

A: Limited recycling exists today but growing powder reuse efforts from companies like Titanium Powder Recycling Initiative from GE Additive, 6K Additive, PyroGenesis Additive, Mutrec and Titanium Recycling Technology show promise for reintroducing affordable powders back into printers or PIM feeds.
