Many metals have high strength, high stiffness, and have good ductility. Some metals, such as iron, cobalt and nickel are magnetic . At extremely low temperatures, some metals and intermetallic compounds become superconductors . All rights reserved.
Pure metals are elements which comes from a particular area of the periodic table.
Examples of pure metals include copper in electrical wires and aluminum in cooking foil and beverage cans. Metal Alloys contain more than one metallic element. Their properties can be changed by changing the elements present in the alloy. Some metal alloys, such as those based on Aluminum, have low densities and are used in aerospace applications for fuel economy. Many metal alloys also have high fracture toughness , which means they can withstand impact and are durable.
