ABSTRACT:
A fortified metal filter possessing a high filtering efficiency, a large pore ratio and a wide net area of fused parts of fine stainless steel wires is prepared by crushing the edges of these wires. The wires utilized in the system are composed of numerous polygonally cross-sectioned fine stainless steel wires. The procedure for preparing such filters, in which only the fused part, which arises from the crushing of the wire edges, possesses a large net area and the metal is diffused into the fused part, is achieved by heating and compressing the system simultaneously.
