Aluminum sheets are lightweight yet strong, offering excellent strength-to-weight ratios. They are more durable and heat resistant compared to plastics, which can deform under heat and are less sturdy. Unlike glass, aluminum is less brittle and does not shatter, making it safer for certain applications. Additionally, aluminum is recyclable and has good thermal and electrical conductivity, which is not the case with plastics. However, plastics are generally cheaper and easier to shape into complex forms, while glass offers better transparency for applications requiring clear visibility. Each material has its advantages depending on the specific requirements of the application.
