What are the differences between metals and plastics?

What are the differences between metals and plastics?

Metals are typically strong, durable, and conductive, while plastics are lightweight, flexible, and resistant to corrosion.

Can you give examples of where each material is used?

Sure! Metals are often used in construction and machinery, while plastics are common in packaging and consumer goods.

Which material is better for outdoor use?

It depends on the application. Metals can rust if not treated, but some are very durable. Plastics can fade or become brittle in sunlight.

What about the environmental impact of each?

Metals can be recycled, reducing their environmental impact, while plastics can take hundreds of years to decompose.

Are there any new materials that combine the benefits of both?

Yes, composite materials often combine metals and plastics to leverage the strengths of both, like in aerospace applications.
