FELTMETAL™ Abradable Seals are porous metal seals made from Technetics Group's metal fibers, designed to minimize engine clearance and prevent wear on rotating components in gas turbine engines. The seals are supplied in segments with typical thicknesses of 0.1 to 0.3 inches, thickness tolerances of ±7% of nominal, length tolerances of +1/16"-0", and width tolerances of ±0.020". Material density ranges from 16% to 32% of solid, and fiber composition is selected based on application temperature requirements.
Technetics Group FELTMETAL™ Abradable Seal material provides superior clearance control in blade tip and labyrinth seal applications up to 1400˚F [760˚C].
With 30 years and over 1,000,000,000 hours of successful operation, it is no wonder that FELTMETAL™ Abradable Seals have been adopted by major gas turbine manufacturers for flow path efficiency improvements.
Technetics Group FELTMETAL™ Abradable Seal material can be manufactured to virtually any size or thickness and can be rolled, formed, or machined to its final configuration.
