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.
A metal can refer to an element, compound, or alloy that is a good conductor of both electricity and heat. Recall the general properties of metallic elements. The electrical and thermal conductivities of metals originate from the fact that their outer electrons are delocalized.
