Question

cite three reasons why ferrous alloys are used so extensively. cite three characteristics of ferrous alloys that limit their use.

Answer 1

Ferrous alloys are extensively used for their strength, magnetic properties, and cost-effectiveness. However, their susceptibility to corrosion, high density, and brittleness at low temperatures limit their use.

Step-by-step explanation:

Ferrous alloys, which are alloys made primarily of iron, are used extensively for several reasons:

1. Strength and durability: Ferrous alloys, such as steel, have high strength and durability, making them suitable for applications that require structural integrity, such as construction and transportation industries.
2. Magnetic properties: Ferrous alloys can exhibit magnetic properties, which makes them useful in applications like electrical transformers and motors.
3. Cost-effectiveness: Ferrous alloys are relatively more affordable compared to other alloys, which makes them a preferred choice for many industries.

However, there are also some characteristics of ferrous alloys that limit their use:

1. Corrosion susceptibility: Ferrous alloys are prone to corrosion, especially in the presence of moisture and oxygen.
2. High density: Ferrous alloys, especially those with higher iron content, are relatively dense, which can limit their use in applications where weight reduction is a priority.
3. Brittleness at low temperatures: Some ferrous alloys can become brittle at low temperatures, which may restrict their use in extreme cold environments.
