∙ 9y agoIt depends on the device Ready-made metallic heating elements made from wire or strip in iron-chromium- aluminium alloys or nickel-chromium. Heating elements for high-temperature furnaces are often made of exotic materials, including platinum, molybdenum disilicide, and silicon carbide. Silicon carbide igniters are common in gas ovens. There's no standard material used for all elements.

Nickel and chromium are combined into an alloy to produce a nickel chromium resistance wire. The mixture is 60% nickel and 16% chromium and has the capacity to operate up to 1000 degrees C. Individual elements used for resistance wire will not reach the operating temperature without breaking down. Combining to elements together over comes this breakdown in individual element materials.

∙ 13y agoWe use alloys for heating elements because alloys do not oxidise readily electric heating devices like toasters , electric iron etc.

Lanthanides are often mixed with more common metals to make what?
Another metal.
Why are alloys often used instead of pure metals?
Alloys are sometimes more useful than pure metals because alloys tend to be stronger though not necessarily. Pure metals tend to be softer than alloys, which are a mix of two or more metals, and therefore get dented, scratched, or broken more easily. Gold used in jewelry is a good example. Metal alloys have different structural and behavioral characteristics than pure metals. Alloying a metal also gives it a different appearance. In some cases alloys may result in a lighter metal without sacrificing other necessary characteristics. They may also be more cost effective.

Explain why metals alloys are often used in place of metals?
There are a few different reasons. 1. Some alloys are stronger than natural metals. 2. Weight, if you need a light weight material, alloys have more to offer, eg. aluminum. 3. Cost 4. Flexibility These are just a few of the many answers.
What can an alloy do?
Alloying one metal with other metal(s) or non metal(s) often enhances its properties.Alloying is changing chemical composition of steel by adding elements with purpose to improve its properties as compared to the plane carbon steel.Alloys are used in some applications, where their properties are superior to those of the pure component elements for a given application. Examples of alloys are steel, solder, brass, pewter, phosphor bronze and an amalgam.
Metal alloys developed in space are often what than alloys processed on Earth?
They are often more uniform.
Metal compounds made of two or more metallic elements are known as?
Metal compounds made of two or more metallic elements are usually called ALLOYS. However, there are true compounds and these are often known simply as inter-metallic compounds.
Explain why other elements are often mixed with metals to make alloys?
Alloys have improved features compared with single metals.
Lanthanides are often mixed with more common metals to make what?
Another metal.
What are alloys in aluminium?
Aluminium alloys are alloys of aluminium, often with copper, zinc, manganese, silicon, or magnesum. A alloy is more than one metal combined to make a greater property

Are coins an element?
No, coins are not an element. Some coins may be made of nearly pure gold, silver, aluminum, or other metal elements, but most present-day coins are made of various metal alloys, often with different composition on the inside than on the outside.
Why are metal things often made of alloy rather than pure metal?
Alloys allow certain metals to be stronger, or lighter, or both
What elements are in alloys?
Alloys are made from a mixture of metals that are usually melted together. In this way brass, pewter, bronze are made. An amalgam which is also an alloy, is easier to make because mercury is a liquid at room temperature and metals dissolve in it.
Why are alloys used instead of pure metals?
Because alloys often have better properties than their parent metals. Stronger, rust resistant etc
Which type of metal is forged the most?
Aluminum was the metal most often forged in this industry classification. Aluminum and its alloys can be forged into many different shapes and sizes.
Is there a metal that begins with f?
Ferrous metals contain iron, from the Latin. There may be other alloys often with proprietary names.
