Titanium powder is more expensive compared to steel powder costs due to complex manufacturing and economies of scale. However, buyers focus on quality, purity and product performance instead for critical applications.
Titanium vs Alternative Powders
Titanium vs. Steel
Titanium has 40% lower density than steel and retains strength better at elevated temperatures. It has excellent corrosion resistance due to surface oxide layer. More expensive than stainless steel powder.
Titanium vs. Aluminum
Almost twice as strong as aluminum powder but with only 60% higher density. Maintains properties at higher temperatures. Much better corrosion resistance than aluminum due to oxide layer.
Titanium vs. Nickel Superalloys
Titanium has lower density providing higher specific strength. Nickel alloys can operate at extreme temperatures exceeding titanium’s useful limits. Titanium cheaper alternative to expensive superalloys.
Titanium vs. Cobalt Chrome
Half the density of cobalt chrome alloys. Excellent biocompatibility unlike concerns with cobalt and chromium release in body. Significantly cheaper material option.

よくあるご質問
Q: What is the difference between commercially pure titanium vs titanium alloy powder?
A: Commercially pure titanium powder has 99.5-99.9% titanium content with low oxygen, nitrogen and carbon. Titanium alloy powders like Ti-6Al-4V contain aluminum, vanadium, or other elements to enhance properties like strength.
Q: What particle size titanium powder is optimal?
A: For pressing and sintering 75-150 microns is common. For additive manufacturing processes, finer 15-45 micron powder is preferred to achieve good resolution.
Q: Does titanium powder require special handling precautions?
A: Yes, titanium fines are flammable and create explosion hazard. Inert gas blanketing and proper grounding is used. Water contact causes hydrogen absorption issues.
Q: How to determine which titanium grade is best for my application?
A: Consult closely with potential suppliers on technical requirements. Ti-6Al-4V is the most common grade but others like Ti-6Al-7Nb suit specific needs. Get test samples to evaluate performance.
Q: What methods can produce titanium powder suitable for 3D printing?
A: Gas atomization and plasma spheroidization create fine spherical titanium powders optimal for additive manufacturing. Hydride-dehydride and mechanical milling methods also produce printable powder.
Q: What post-processing is required on additively manufactured titanium parts?
A: Hot isostatic pressing (HIP) helps eliminate porosity in printed parts. Additional heat treatments, surface finishing, and machining may be needed depending on final properties and tolerances required.
