Materials that can be pulled into wires are called ductile. Many metals are ductile, including aluminium, copper, iron and tin. Ductile metals have commercial applications. For example, wires of aluminum and copper are used for carrying electric current. Gold and silver are also ductile but very expensive.Know More
Not all metals are ductile. Some metals break on application of tensile stress and cannot be pulled into wires. Lead is an example of a soft metal that cannot be pulled into wires.
Ductility in metals decreases with an increase in temperature. The property of ductility is due to the formation of bonds in metals at the atomic and molecular levels. Most ductile metals are also malleable and can be beaten into sheets.Learn more about Natural Resources
A list of a country's natural resources is posted on the World Factbook of the Central Intelligence Agency. The list includes mineral deposits, petroleum, hydroelectric power and other sources of economic gain.Full Answer >
Thousands of products are made with coal or coal by-products, including aspirins, soap, dyes, solvents, plastics, and fibers such as rayon or nylon. Coal is an important ingredient in production of products that require activated carbon, carbon fiber or silicon metal. Activated carbon is an essential ingredient in the production of air purification and water filters as well as kidney dialysis machines.Full Answer >
Canada has an abundance of natural resources, including minerals, rare earth elements, wildlife, coal and hydropower. Minerals and elements mined in the country are iron ore, silver, copper, nickel and gold. Other natural resources include fish, molybdenum, diamonds and potash.Full Answer >
Aluminum, copper, tin, mild steel, platinum and lead are examples of ductile materials. Ductile materials can be stretched without breaking and drawn into thin wires. Ductility is an important property for manipulating these metals by hammering, drawing or rolling. It makes possible their use for making electrical wires, pipes, plates and other metalworks.Full Answer >
