Iron is classified for its on the chemical composition and mechanical properties are
• It come contact easily in air .
• When humidity ( moisture ) and air come contact on it , it become rust .
• Rust is a reddish brown layer on the Iron object.
• Iron is a metal with ductile , shiny and can be easily hammered .
• It is a fourth common metal found in earth 's crust.
• From being a crucial building block of steel to nourishing plants and helping carry oxygen in your blood .
• To make steel, iron ore is first mined from the ground. It is then smelted in blast furnaces where the impurities are removed and carbon is added. In fact, a very simple definition of steel is iron alloyed with carbon, usually less than 1%.
• Pure iron is soft and easily shaped because its atoms are arranged in a regular way that lets layers of atoms slide over each other. Pure iron is too soft for many uses. Iron from the blast furnace is an alloy of about 96 percent iron, with carbon and some other impurities.
