Which materials are commonly used in engineering?

Metals and polymers are indeed commonly used materials in engineering due to their distinct properties and versatility. Metals, such as steel and aluminum, are favored for their strength, durability, and conductivity. They are fundamental in structural applications, machinery, and electrical components. Polymers, on the other hand, offer a wide range of characteristics, such as being lightweight, resistant to corrosion, and easily moldable, making them ideal for products like casing, insulation, and various consumer goods.

The combination of metals and polymers allows for innovative engineering solutions where the strengths of each material complement one another. This synergy is essential in creating products that require both strength and flexibility, showcasing the importance of understanding material properties in engineering design.
