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.
They are Gold, Silver, and Platinum. These three metals and the alloys that utilize them are referred to as the Noble Metals. Noble Metals have four properties in common. 1  They are precious metals and are also used as currency (a store of value) because of their intrinsic value.
