Why Alloys Are Used In Electrical Heating Devices?
Alloys generally have a high melting point, good electrical conductivity, and resistance to corrosion and erosion. These particular properties make alloys the material of preference for use in electrical heating devices. The resistive and heat loss limits for metal are not significantly different from other materials.
Electrical heating devices must have a high melting point to not melt at high temperatures when an electrical current flows through them. Hence, alloys are used in electrical heating devices.
Together, nickel and chromium produce Nichrome. Typically, alloys, such as Nichrome are more durable than pure metals. Instead of being uniform, they are composed of atoms of varying sizes.
It implies that the atomic layers cannot easily slide over one another, resulting in a far stronger alloy than any pure metals used in isolation.
As is common knowledge, alloys have a higher resistivity and melting point than pure metals. Therefore, alloys cannot burn or oxidize readily at higher temperatures. Now, because we need higher temperatures in heating equipment, we employ alloys.
Nichrome, for instance, is a mixture of nickel and chromium. Alloys, such as Nichrome, are often tougher than pure metals.
They are comprised of atoms of varying sizes instead of being homogenous. It implies that the layers of atoms cannot readily glide over one another, resulting in a far stronger alloy than any of the pure metals it includes in isolation.
Advantages Of Alloys
Enhance tensile strength:
Alloys are hard by nature than their constituent metal. Tensile strength is the property of a material that prevents deformation or distortion.
Enhance corrosion resistance:
An alloy is a difficult to corrode or rust than its constituent metal in the same environment and under the same conditions. Also made of mixtures of metals which indicates a certain ability to resist corrosion.
Enhance hardness:
Hardness is the tendency or resistance to develop scratches on the surface, also known as wear resistance.
Provide better castability:
Casting is a method of producing metal parts by pouring molten metal into a mold. Casting is more expensive than the other production process because of its high cost, but it is often used to make complex shapes that would be difficult to make in other ways.
Less porosity and better surface finish are obtained in casting than in other processes such as forging. It can be due to the lower melting point of alloys relative to their constituent metals. It is also easier for gases to escape from pores in the molten alloy solidifying inside the mold.
