Abstract: Described is an industrial brush (1) comprising a brush body (2) obtained by the solidification of a metal in which the metal wires are locked in a rigid fashion for a first portion (3) thereby having a rigid body. Also described is a process for making a brush (1) comprising the steps of feeding in a mould (8) a metal in the molten state (melting temperature less than 2000° C.), in such a way that the first portion of the metal wires (3) is immersed in the metal which, when solidifying, forms a brush body with a rigid structure with a high mechanical strength such as to render perfectly stable the operation of the brush at high speeds and at high temperatures. During solidification of the molten metal there is also a heat treatment on the metal wires which improves their mechanical characteristics.
