Alloys are often preferred for making heating devices due to their ability to withstand high temperatures and resist oxidation, which enhances durability. The specific composition of an alloy can be tailored to improve thermal conductivity and electrical resistance, making them efficient for heating applications. Additionally, the mechanical strength of alloys allows them to maintain structural integrity under the stresses of heating and cooling cycles. Overall, these properties make alloys more suitable than pure metals for reliable and long-lasting heating devices.

How are smart memory alloys work?
Smart memory alloys, like Nitinol, are materials that can "remember" their original shape and return to it when heated. This is achieved due to a phase transformation that occurs at a specific temperature, allowing the material to change shape and then revert back by heating or cooling. This property makes smart memory alloys useful in various applications such as medical devices, robotics, and actuators.

Why does manufacturing alloys make a more beneficial metal?
Alloys have improved mechanical properties, hardness, resistance to corrosion, resistance to heating, stable crystalline structure etc. compared with pure metals.
What are the elements of electrical heating devices usually made of?
Generally the Kanthal alloys are used. <<>> Depending on the temperature range that is needed, the heating element could be composed of; iron-chromium-aluminium, nickel-chromium, nickel-iron or copper-nickel. The maximum temperature range for each alloy is 1400 C, 1250 C, 600 C and 600 C respectively.
Why are alloys prepared and how are they used?
Generally by melting together the components of the alloy. Also by pressing and sintering the components, in powder metallurgy.
What is the materila used in heating appliances?
alloys are used in heating appliances to increase the heat conductivity in the electrical heating devices.
Alloys are used in electrical heating devices rather than pure metals. Give reason.?
Alloys are used rather than pure metals in electrical heating devices since they have low electrical conductivity and also a low melting point. Usually the alloys don't have a single melting point; they have a range of melting points. The temperature at which melting begins is called the SOLIDUS and the temperature at which melting is complete is called the LIQUIDUS.Student
Explain why other elements are often mixed with metals to make alloys?
Alloys have improved features compared with single metals.
Why are alloys prepared?
Alloys have useful properties that are not found in the pure metals from which they are mixed. You can make alloys that are stronger, lighter, more corrosion resistant, and so forth, as compared to pure metals at a comparable price range.
How are metal alloys created in manufacturing?
Metal alloys are primarily created by being heating, melting and blending, then allowed to cool and harden. This is common in alloy manufacturing plants.
Explain why are alloys a useful improvement over pure metals?
Alloys are useful improvement over pure metals because they tend to be stronger.

Why are alloys often used instead of pure metal elements?
In no particular order: # cost # corrosion resistance # optimization of strength to weight # specific mechanical behaviors (eg: memory metal) # ease of working, by different manufacturing methods
