foil is another main use of aluminium. foil is used in our everyday lives. it is used as an insulator to cover cutlery and keep things clean
**properties: lightweight, ductile and very malleable. Gold is a good conductor of electricity and heat. It is not affected by exposure to air or to most reagents. It is inert and a good reflector of infrared radiation. Gold is usually alloyed to increase its strength.
silver properties: similar to gold, silver has very good properties making it a very useful metal In industry. High ductility, malleability, conductivity and a lustrous white appearance are some of the physical properties of silver. Pure silver has the highest electrical and thermal conductivity of all the metals. Because its natural occurrence is relatively rare, silver is considered a precious metal.
properties of steel and uses: steel is a very common and useful metal used in industry. the main properties for steel are Tensile Strength. Tensile strength is the amount of stress that a substance can take before becoming structurally deformed. another property is Ductility. One of the useful mechanical properties of steel, is its ability to change shape on the application of force to it, without resulting in a fracture.
the main uses of steel in industry: In packaging, steel is often used for food and beverage cans, aerosols, bottle tops and containers to safely store and transport paint and chemicals. In the energy sector, steel is used to construct gas and oil wells, pipelines and turbines.
