Metals


FormSolid at room temperature (except mercury); available in various forms such as sheets, bars, rods, wires, and powders
ColorVaries by type; silver, gray, gold, copper, and other metallic hues
DensityVaries by metal; aluminum: 2.7 g/cm³, steel: 7.85 g/cm³, gold: 19.3 g/cm³
Melting PointVaries by metal; aluminum: 660°C, iron: 1,538°C, copper: 1,085°C, gold: 1,064°C
Electrical ConductivityHigh; metals like copper and silver are excellent conductors, while others like steel have lower conductivity
Thermal ConductivityHigh; metals efficiently transfer heat, making them ideal for heat exchangers and cookware
MagnetismFerromagnetic metals like iron, nickel, and cobalt are magnetic; others like aluminum and copper are non-magnetic
HardnessVaries; tungsten and titanium are hard, while metals like lead are soft
DuctilityHigh ductility; metals can be stretched into wires (copper, aluminum)
MalleabilityMetals can be hammered into sheets without breaking (gold, silver, aluminum)
Corrosion ResistanceSome metals like stainless steel, aluminum, and titanium are corrosion-resistant; others like iron are prone to rust
Tensile StrengthVaries; high tensile strength in metals like steel and titanium, lower in softer metals like lead
DensityMetals are generally dense, with values depending on the type and purity of the material
ApplicationsUsed in construction (steel, aluminum), electronics (copper, gold), jewelry (gold, silver), and industrial machinery
Alloy FormationMetals can form alloys with other metals (e.g., steel is an alloy of iron and carbon; bronze is an alloy of copper and tin)
MachinabilityVaries by metal; some like aluminum and brass are easily machinable, while others like titanium require special tools
Surface FinishCan be polished, brushed, coated, or plated for aesthetic or protective purposes
