The material is used as a cover as it does not react with water and air.
- These materials refer to the ones which are able to withstand harsh circumstances and do not corrode.
- Some of the metals under this category are Bronze, Brass, and Copper.
- A common and popular example of such a material is plastic.
- Air and water do not cause this material to react. As a result, when exposed to moisture and air, they do not rust.
- They are noncorrosive in nature. Even when kept out in the open for a long time, this material does not even degrade.
- Even when exposed to potent substances, the material has no reaction.
- For example -
- Plastic bottles rather than metal containers are used to hold the cleaning supplies we use at home.
- Plastics are even used in packaging, flooring, construction etc.
