The following are the application areas of iron:
As the primary constituent of ferrous metals/alloys and steels
Alloyed with carbon, nickel, chromium and various other elements to form cast iron or steel
In magnets
In fabricated metal products
In industrial machinery
In transportation equipment
In instruments
USES OF SILVER IN MEDICINE & HEALTHCARE

1. Silver sulfadiazine used as a topical cream to treat burns. It made WHO’s list of essential medicines, as an anti-infective medicine.
2. Treatment of warts and corns usually in the form of a caustic pencil. The silver compound silver nitrate, is widely used, and is formed by reacting silver with nitric acid.
3. SilverCoat Foley catheters are used in urology to prevent urinary tract infections from catheter use. Canadian company Covalon is pushing the boundaries on medical technologies that saves lives. This SilverCoat technology is one of them.

Iron is an enigma – it rusts easily, yet it is the most important of all metals. 90% of all metal that is refined today is iron. Most is used to manufacture steel, used in civil engineering (reinforced concrete, girders etc) and in manufacturing.
silver is used for jewellery and silver tableware, where appearance is important. Silver is used to make mirrors, as it is the best reflector of visible light known, although it does tarnish with time. It is also used in dental alloys, solder andbrazing alloys, electrical contacts and batteries.
mercury was also commonly used in batteries, fluorescent lights, feltproduction, thermometers and barometers. Again, these uses have been phased out. Mercury easily forms alloys, called amalgams, with other metals such as gold, silver and tin.
Lead is still widely used for car batteries, pigments, ammunition, cable sheathing, weights for lifting, weight belts for diving,lead crystal glass, radiation protection and in some solders. It is often used to store corrosive liquids.
