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.Know More
Ductile materials have varying degrees of ductility depending on temperature, metallic bonds, material constituents and working process to which the material is subjected. Varying the temperature can either make a material more or less ductile. For example, lead and tin are ductile while cold, but they become brittle when heated to their melting points. Therefore, the temperature at which a metal transitions from being ductile to brittle must be considered in the selection of materials in addition to knowing the mechanical processes to which is to be subjected.
Materials are also highly ductile because of their characteristic metallic bonds. As such, metals are generally ductile, but the composition of these metallic materials is not always pure. They have alloying constituents, which affects ductility. For example, increasing the carbon component of steel decreases ductility. Another example is zinc, which is brittle at low temperature, but when heated up and alloyed with copper to form brass, it becomes somewhat ductile as well.Learn more about Chemistry
Many of the materials that are used to muffle sound are made from porous substances, such as cork or foam rubber. Mineral wool is a sound-proofing material made from inorganic fibers that can be shaped to fit into areas between walls to provide a greater degree of sound reduction in a room. Thicker and denser materials tend to muffle sound better than lighter materials, and rougher surface areas will absorb more sound than smooth surfaces, which will reflect sound waves instead.Full Answer >
Aluminum, like all other metals, conducts electricity, but it is not the best conductor of electricity. Pure gold, pure copper and pure silver all conduct electricity better than aluminum though aluminum is a more efficient conductor than zinc, nickel, brass, bronze, iron, steel, platinum and lead.Full Answer >
Aluminum is a silver-grey metal element with a density of 2.7 grams per cubic centimeter. While remaining ductile and malleable, aluminum has a high tensile strength. Solid at room temperatures, aluminum melts at 1,220.58 degrees Fahrenheit and boils at 4,566 degrees Fahrenheit.Full Answer >
Aluminum is a lightweight, ductile metal with a density roughly one-third that of steel. Despite its low density, aluminum is strong for its weight and can easily be alloyed with other metals to produce useful compounds.Full Answer >
