PuKong Prototype-As an experienced prototype company in China , understanding the key characteristics of PEEK (Polyether Ether Ketone) and Titanium
prototypes helps in guiding customers toward the best material choice
for their applications. Below is a detailed comparison of their applications, advantages, and limitations.
1. PEEK Prototypes
Applications:
Medical & Dental: Surgical instruments, spinal implants, and dental components (biocompatible & sterilizable).
Aerospace: Lightweight, high-strength components like bushings, seals, and insulation parts.
Automotive: High-temperature-resistant gaskets, bearings, and electrical connectors.
Oil & Gas: Chemical-resistant seals and valve components.
Electronics: Insulating parts for high-heat environments.
Advantages:
✔ High Temperature Resistance – Stable up to 250°C (482°F).
✔ Chemical Resistance – Resists acids, solvents, and hydrocarbons.
✔ Biocompatibility – FDA-approved for medical implants.
✔ Lightweight – Lighter than metals, ideal for weight-sensitive applications.
✔ Wear & Fatigue Resistance – Excellent for moving parts.
Limitations:
✖ High Cost – More expensive than standard plastics like ABS or nylon.
✖ Difficult Machining – Requires specialized CNC tools due to its toughness.
✖ Not as Strong as Metals – Lower tensile strength compared to titanium.
2. Titanium Prototypes
Applications:
Aerospace: Aircraft structural components, engine parts, and fasteners.
Medical: Implants (hip joints, bone screws) due to biocompatibility.
Automotive & Motorsports: High-performance parts like connecting rods and exhaust systems.
Military & Defense: Armor plating and lightweight weapon components.
Marine Industry: Corrosion-resistant fittings and propellers.
Advantages:
✔ Exceptional Strength-to-Weight Ratio – Stronger than steel but 45% lighter.
✔ Corrosion Resistance – Ideal for harsh environments (saltwater, chemicals).
✔ Biocompatibility – Non-toxic, integrates well with human tissue.
✔ High-Temperature Performance – Maintains strength up to 600°C (1112°F).
✔ Long Fatigue Life – Excellent for cyclic loading applications.
Limitations:
✖ High Cost – Expensive material and machining process.
✖ Difficult to Machine – Requires slow speeds, specialized tooling, and high-power CNC machines.
✖ Poor Thermal Conductivity – Not ideal for heat dissipation applications.
3. PEEK vs. Titanium: Which to Choose?
| Factor | PEEK | Titanium |
|---|
| Weight | Very Light | Light but heavier than PEEK |
| Strength | Good (Plastic) | Excellent (Metal) |
| Heat Resistance | Up to 250°C | Up to 600°C |
| Corrosion Resistance | Excellent | Exceptional |
| Biocompatibility | Yes | Yes |
| Machining Difficulty | Moderate | High |
| Cost | High | Very High |
Best Choice for:
PEEK: When lightweight, chemical resistance, and electrical insulation are critical (e.g., medical, aerospace).
Titanium: When extreme strength, corrosion resistance, and high-temperature stability are needed (e.g., aerospace, medical implants).
