Which type of components are typically reused if not corroded?

The choice of metal or plastic brackets is particularly relevant in the context of component reuse. Metal brackets are often utilized for their durability and strength. If these components are not corroded, they maintain their structural integrity and can be effectively reused in various applications. Plastic brackets, while not as strong as metal, can still provide good support and are resistant to environmental factors, making them suitable for reuse if they remain in good condition.

In contrast, the other options may not be as readily reused due to various characteristics. Plastics and rubber can degrade over time, potentially leading to a loss of functionality or safety issues. Insulation materials might lose their effectiveness with age or damage, making their reuse questionable. While circuit boards could theoretically be reused, they often contain sensitive components that might become unserviceable or outdated, limiting their viability for reuse. Thus, metal or plastic brackets stand out as components more commonly reused when not subjected to corrosion.
