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.
A low density, permeable structure of cells and continuous ligaments offering a high surface area to volume ratio, and also a high strength to weight ratio.
Owing to the nature of this material, dimensions are nominal.
