Product Introduction

Our titanium powder is produced using Electrode Induction Gas Atomization (EIGA), a highly efficient process for producing high-performance titanium alloy powder. Its core advantages are as follows:

1. High sphericity and excellent flowability

The EIGA process, through electrode induction melting combined with inert gas atomization, can produce titanium powder with extremely high sphericity (>95%). The powder has a smooth surface, low porosity, and flowability (≤25s/50g) significantly better than non-spherical powders produced by traditional hydrogenation-dehydrogenation methods. This characteristic allows for uniform powder spreading in 3D printing (such as SLM and EBM processes), improving the density and mechanical properties of the formed parts.

2. Low oxygen content and high purity

Because the entire process is completed under inert gas (such as argon) protection, the EIGA process avoids the oxidation contamination of titanium powder. The oxygen content can be stably controlled below 0.15%, and the nitrogen content is <0.05%, meeting the standards for aerospace-grade titanium powder (such as AMS 4999). Compared to the hydrogenation-dehydrogenation method (where oxygen content is easily exceeded), its chemical purity is more suitable for high-demand applications such as aerospace and medical implants.

3. Controllable particle size distribution

EIGA technology can precisely control the powder particle size range (for example, 15-53μm or 53-150μm) by adjusting atomization parameters (such as gas pressure and melt temperature), adapting to the needs of different additive manufacturing processes (such as fine powder for selective laser melting and coarser powder for electron beam melting).

4. No crucible contamination risk

Using consumable electrode melting eliminates the need for ceramic crucibles, completely avoiding contamination of the titanium melt by crucible materials in traditional atomization methods, ensuring extremely low impurity content in the powder.

5. Suitable for high-end manufacturing fields

With its high purity, narrow particle size distribution, and excellent flowability, EIGA titanium powder has become a core raw material for key components such as aerospace engine blades, complex aerospace components, and personalized orthopedic implants, particularly in applications requiring high fatigue strength and corrosion resistance.

Comparison with other processes

• Gas atomization method: Although the cost is low, it is easy to produce hollow powder, which affects the performance of the formed parts; the EIGA process avoids this problem through contactless melting.
• Hydrogenation-dehydrogenation method: The powder has a high oxygen content (>0.15%), which is difficult to meet aerospace standards, and is mostly non-spherical with poor flowability.
• Rotating electrode method: Although the purity is comparable to EIGA, the cost of the electrode rod is high and the production efficiency is low, limiting large-scale application.

In summary, the EIGA process combines performance advantages and industrial applicability in the preparation of high-end titanium powder, and is one of the key technologies driving technological upgrades in additive manufacturing, aerospace, and other fields.
