Product Description

Feltmetal® Acoustic Media Provides High Temperature, Lightweight Noise Control
Feltmetal® Acoustic Media is an engineered, porous material made of sintered metal fibers. Fiber size,
porosity and thickness combine to control the desired flow and sound absorption. To enhance tructural
properties, the metal fibers may be reinforced by sintering to screen mesh or perforated
plate.
Feltmetal® Acoustic Media is produced from fibers having diameters ranging from 6 to 150 microns. Finer
fibers offer the advantage of lighter weight and lower non-linearity factors. 
Alloys available include:
Stainless Steels for service temperatures up to 930°F [500°C] 
Hastelloy-X for service temperatures up to 1100°F [600°C] 
FeCrAlY for service temperatures up to 2000°F [1100°C]
