What are the advantages of using an alloy over a pure metal?
Compared to pure metals, alloys can be stronger, more resistant to damage and more versatile. The advantage of alloys differs depending on the specific alloy. Some are better than pure materials, while some are worse. Most alloys are formed for one or two specific properties, like strength and rust resistance.
A metal is the pure chemical element being iron, copper, chrome, gold, whatever. An alloy is a mixture of various elements: iron, chrome, copper, zinc, whatever. Most metals as we use them are mixtures, in metal terms: alloys. Originally Answered: What's the difference between metal and alloy?
- Gold is yellow and copper is red, the only two colored pure metals. As mentioned earlier, for most uses of gold the pure metal is too soft on its own and is therefore hardened by the addition of alloying elements, copper, silver, nickel, palladium and zinc.
- Pure aluminum is relatively soft and not the strongest of metals. When melted together with other elements such as copper, manganese, silicon, magnesium, and zinc, however, it forms alloys (a substance composed of two or more metals or of a metal and a nonmetal) with a wide range of useful properties.
- It is made up of two or more chemical elements, of which at least one is a metal. An alloy has properties different from the metals it is made of. Most alloys are made by melting the metals, mixing them while they are liquid to form a solution, then leaving them to cool and turn solid again.
Iron and steel. Pure iron is too soft for many uses. Layers of atoms slide over each other when metals are bent or stretched. Iron from the blast furnace is an alloy of about 96 percent iron, with carbon and some other impurities.
- Nickel Alloys
- Alumel (nickel, manganese, aluminum, silicon)
- Chromel (nickel, chromium)
- Cupronickel (nickel, bronze, copper)
- German silver (nickel, copper, zinc)
- Hastelloy (nickel, molybdenum, chromium, sometimes tungsten)
- Inconel (nickel, chromium, iron)
- Monel metal (copper, nickel, iron, manganese)
- Bronze is an alloy of tin and copper. Tin and lead are alloyed to make pewter and solder. An alloy of tin and niobium is used to make superconductive wire. Type metal, fusible metal, bell metal and Babbitt metal are other examples of tin alloys.
- Most pure metals, like aluminium, silver and copper, come from the Earth s crust. They are found in ores solid materials called minerals, usually occurring in rock, from which the pure metal has to be extracted. The properties of pure metals can be improved by mixing them with other metals to make alloys.
