PEEK: The Leader in Metal Replacement - Engineering Properties
Polyether ether ketone (PEEK) is the premier choice for high-performance CNC machining, offering an unmatched combination of mechanical strength and thermal stability. As a leading chemical resistant plastic, it serves as a superior metal replacement in weight-sensitive aerospace and medical applications.
With a melting point of $343^circ text{C}$ and a continuous service temperature of $260^circ text{C}$, PEEK components maintain dimensional stability where other polymers fail. Its near-zero moisture absorption ensures precision tolerances of $pm pm 0.01text{mm}$ are held even in high-humidity environments.
Our precision PEEK machining process leverages the material's high fatigue resistance. This makes it ideal for load-bearing parts like aerospace bushings, manifold blocks, and structural implants that must endure constant mechanical stress without deformation.
Furthermore, PEEK’s inherent biocompatibility and resistance to aggressive sterilization (autoclave) make it the gold standard for medical device machining, providing long-term reliability in clinical and surgical settings. To learn more about various material properties, visit our materials page.
