A metal is generally considered to be a pure element which readily forms cations. Metals are characterised by their opacity and high thermal and electrical conductivities, the latter properties resulting from the delocalised and mobile nature of the electrons over the crystal structure.
Mesh is available as either a woven wire or electroformed product; in all cases, the quoted aperture sizes are nominal.
Wire mesh: a material which is woven from metal wires to provide a thin grid with a regular series of holes.
Electroformed mesh: a product made by electroplating the mesh geometry through a mask onto a substrate which is subsequently etched away.
