How does PEEK compare to metal?
PEEK offers several advantages over metals for demanding applications:
Performance advantages:
Continuous use temperature 260°C matches many metal applications
Specific strength (strength per unit weight) often exceeds metals
Complete chemical inertness (no corrosion vs metal oxidation/degradation)
Excellent wear resistance in dynamic applications
Electrical insulation properties (vs metal conductivity) (Note, carbon fibre filled PAEKs – both as compounds and composites – are conductive, and VICTREX ESD 101 is partially conductive.
Practical advantages:
40-50% weight reduction vs metal equivalents
Complex geometries via injection moulding (vs machining limitations)
Lower assembly costs (snap fits, welded joints vs fasteners)
Reduced maintenance (no corrosion protection required)
Trade-offs:
Higher material cost per kg (offset by part weight reduction and lifecycle savings)
Lower absolute strength than some metals (but higher specific strength)
Processing temperature requirements (360-400°C vs metal forming)
