CPTi Powder: The Ultimate Guide for 2025

Overview

CPTi powder, or Commercially Pure Titanium (CP Ti) powder, is widely used in aerospace, biomedical, chemical processing, and additive manufacturing industries due to its superior corrosion resistance, high ductility, and biocompatibility. Unlike titanium alloys such as Ti-6Al-4V, CPTi does not contain additional alloying elements, making it ideal for applications requiring high purity, excellent weldability, and superior oxidation resistance.

CPTi is classified into four grades (Grade 1 to Grade 4) based on oxygen content and mechanical properties. Grade 1 is the softest and most ductile, while Grade 4 offers the highest strength.

Key Properties

✔ Exceptional corrosion resistance, making it ideal for marine, chemical, and aerospace applications
✔ Superior biocompatibility, making it the preferred material for medical implants and prosthetics
✔ Lightweight yet strong, providing an excellent strength-to-weight ratio
✔ High weldability and machinability, making it easier to process than titanium alloys
✔ Excellent thermal and electrical conductivity, useful in energy and electronics industries

How to Choose the Right CPTi Powder

Selecting the best CPTi powder depends on several factors, including particle size distribution, atomization process, and application-specific requirements.

1. CPTi Grades

2. Particle Size Distribution (PSD)

• Fine powders (15-45µm) → Best for LPBF (Laser Powder Bed Fusion)
• Medium powders (45-105µm) → Suitable for EBM & Binder Jetting
• Coarse powders (50-150µm) → Used in DED (Direct Energy Deposition)

3. Powder Morphology

• Spherical Powder → Best for 3D printing and powder bed fusion technologies
• Irregular Powder → Suitable for Binder Jetting & Sintering

4. Atomization Process

• Gas-Atomized Powder → High purity, excellent flowability, best for 3D printing
• Plasma-Atomized Powder → Ultra-high purity, best for specialized aerospace and high-performance applications

Production Methods

The manufacturing process of CPTi powder plays a critical role in defining its particle morphology, purity, and mechanical performance, which directly affect its use in additive manufacturing, medical applications, and aerospace components.

Comparison of Production Methods

1. Gas Atomization (GA)

Process:

• CPTi is melted and atomized using high-pressure inert gas (argon or nitrogen), rapidly cooling the droplets into fine, spherical particles.

Advantages:
✔ Highly spherical morphology, improving flowability and printability
✔ Low oxygen content, preventing oxidation defects
✔ Excellent particle size uniformity, ensuring consistent layer deposition in additive manufacturing

Best for: Laser Powder Bed Fusion (LPBF), Electron Beam Melting (EBM), and Direct Energy Deposition (DED)

2. Plasma Atomization (PA)

Process:

• CPTi wire is fed into a high-energy plasma torch, melting it into fine droplets that form highly spherical powder particles.

Advantages:
✔ Perfect spherical shape, ensuring superior flowability in powder bed fusion processes
✔ Ultra-high purity, making it ideal for aerospace and biomedical applications
✔ Minimal satellite particles, leading to superior print quality

Disadvantages:
✖ Higher production costs
✖ Limited scalability for large-scale production

Best for: High-performance aerospace and medical implants

3. PREP (Plasma Rotating Electrode Process)

Process:

• A rotating CPTi electrode is melted by plasma while centrifugal force atomizes the molten material into fine spherical particles.

Advantages:
✔ Ultra-high purity, with minimal contamination
✔ Highly spherical morphology, leading to excellent flowability
✔ Minimal porosity, making it ideal for medical implants and aerospace applications

Disadvantages:
✖ Very high cost
✖ Limited scalability

Best for: Biomedical implants, aerospace components requiring high purity

Cost Analysis in 2025

The cost of CPTi powder is influenced by factors such as production method, particle morphology, purity level, and application-specific requirements.

Factors Affecting Cost

1. Production Method – PREP and plasma-atomized powders are the most expensive, while gas-atomized powders offer a more balanced cost-performance ratio.
2. Particle Shape – Spherical powders (for AM) are more expensive than irregular powders.
3. Purity Level – Higher purity = Higher cost.
4. Market Demand – Increased demand from aerospace, medical, and high-performance applications influences pricing.
