With more than 50 years of field-proven performance, FELTMETAL™ Abradable Seals from Technetics Group have become the trusted choice of major Aviation and Power Generation Gas Turbines manufacturers worldwide. Designed to enhance flow path efficiency, these advanced materials deliver superior clearance control in blade tip and labyrinth seal applications.
Why Choose FELTMETAL™ Abradable Seals for your Clearance Control Needs?
- Pre-Brazed Solution
Technetics offers pre-brazed segments or complete elements that eliminate the need for brazing or spraying.
- No special tools or processes required
- Reduced maintenance/assembly time and cost
- Available through a global partner network.
- Excellent Oxidation Resistance
Excellent oxidation resistance up to 1500°F (815°C). Contact us for our white paper on oxidation resistance.
- Heat Dissipation/Convection
The FELTMETAL™ porosity enhance thermal management by dissipating heat away from the casing, while maintaining sealing integrity and performance.
Variable pore sizes, as well as some interrupted or blind passageways through the material can limit the flow of fluid all the way through the material reducing heat dissipation and convection through engine casing.
- Customizable for Performance
Flexibility to tailor abradability vs erosion resistance to meet your requirements. Contact us for additional information.
Whether you’re designing for new systems or upgrading existing platforms, our clearance control solutions help you push the boundaries of performance, durability, and efficiency.
