Sintered Media (Diffusion Bonding)

Mesh layers, powder or fibers bonded in a vacuum furnace into rigid porous filters. 19 products in the catalog are made with this process.

How it is made

Layers of woven mesh, metal powder or metal fibers are pressed and heated in a vacuum or hydrogen furnace just below melting point, so the touching wires or particles diffuse into one another and fuse. The result is a rigid porous plate, tube or felt that can be cut, rolled and welded.

What the process can do

Ratings from about 0.5 µm (powder) to 200 µm (mesh laminate); stainless 316L, Hastelloy, Inconel, Monel, nickel, titanium and bronze.

Best for

Strong, cleanable filters for high pressure and temperature, back-washing, catalyst recovery, gas and polymer filtration.

Limits

Higher cost than woven cloth, and powder parts are less ductile — they dislike bending and impact.

Design & ordering tips

Specify micron rating together with permeability or allowable pressure drop, and the welding or fitting details.
