Construction inflation. Building costs throughout 2011 rose steadily and although theyâre expected to stabilise during 2012 inflationary pressures are nevertheless set to remain as labour wage strains and competitive labour forces continue to affect input costs.
Physical Properties. Metals differ so widely in hardness, ductility (the potentiality of being drawn into wire), malleability, tensile strength, density, and melting point that a definite line of distinction between them and the nonmetals cannot be drawn. The hardest elemental metal is chromium; the softest, cesium.
0. Physicist: The magnetic properties of a material are governed entirely by the configuration of the electrons in that material. In metals there are two types of electrons: bound electrons and free electrons. The free electrons are free to move between atoms, and are the cause of conductivity in metals.
