2. Alloys Alloy is a solid combination of atoms of two or more metals. Alloy is a solid combination of atoms of two or more metals. Like penny in got zinc chloride solution produced a silvery alloy of zinc and copper called y-brass. When you heated the penny in the burner flame, the zinc and the copper atoms mixed more.

Brass has a golden color, unlike either zinc or copper and it is harder than copper metal. Brass has a golden color, unlike either zinc or copper and it is harder than copper metal. In addition to alloys composed of “solid solution” of two or more metal other useful alloys include some that are well-defined compounds that is they have a constant definite ratio of component metallic atoms. Like Ni 3 Al a low-density strong metallic alloy of nickel and aluminum that is used as a component of jet aircraft engines.

3. Alloy substance with metallic properties that consists of a metal fused with one or more metals or nonmetals. Alloys may be a homogeneous solid solution, a heterogeneous mixture of tiny crystals, a true chemical compound, or a mixture of these. Alloys are used more extensively than pure metals because they can be engineered to have specific properties. For example, they may be poorer conductors of heat and electricity, harder, or more resistant to corrosion. Alloys of iron and carbon include cast iron and steels; brass and bronze are important alloys of copper; amalgams are alloys that contain mercury; and chromium is an important additive in stainless steel. Because pure gold and silver are soft, they are often alloyed with one another or with other metals. New alloys are being engineered for use in new technology, including materials for the space program. Metallic glasses and crystalline alloys have also been developed, and metal alloys are sometimes bonded with ceramics, graphite’s, and organic materials as composites.

4. Alloy steel is steel that contains more than one alloying material other than carbon. The addition is deliberately done to achieve certain physical properties. It generally contains silicon and manganese maintaining the same level as carbon steel. There are further additions of chromium, nickel and vanadium. Not so often add-ons of boron, columbium, tungsten, and nickel are found as well. Alloy steels are vacuum melted and are available in sheet, bar, pipe, plate, rod and wire forms. These types of steel plates are found in precision flame cut patterns and shapes, for use in power generation, marine offshore construction, and power vessel fabrication industries. They are available in varied grades and thickness.

5. Alloy wheels are automobile (car, motorcycle and truck ) wheels which are made from an alloy of aluminum or magnesium metals. Alloy wheels differ from normal steel wheels because of Alloy wheels differ from normal steel wheels because of their lighter weight, which improves the steering and the speed of the car, however some alloy wheels are heavier than the equivalent size steel wheel. Alloy wheels are also better heat conductors than steel wheels, improving heat dissipation from the brakes, which reduces the chance of brake failure in more demanding driving conditions.
