Regarding a diaphragm made from multiple materials, which is a common limitation?

A diaphragm constructed from multiple materials does indeed face limitations tied to temperature constraints, which can vary significantly depending on the materials used. Each material has its own properties and temperature thresholds, meaning that if the operational environment exceeds the limits of one or more of the materials, the diaphragm could fail or perform poorly.

Using multiple materials can lead to complications when those materials have different thermal expansion rates, which can affect the structural integrity and performance of the diaphragm as temperatures change. Additionally, the effectiveness of the diaphragm in applications such as pressure control or sealing can be compromised if one material's temperature tolerance is exceeded. Therefore, understanding the temperature limitations of each material is crucial for ensuring reliable operation in various environments.
