Sintered metal fiber felt is an advanced porous metal filtration material manufactured from micron-scale metal fibers with different diameters through fiber laying, lamination, and high-temperature sintering processes. The multi-layer fiber structure creates a graded pore distribution throughout the material thickness, enabling precise filtration performance and high contaminant holding capacity.
