What materials are used to make mechanical seal rings?

Mechanical seal rings are commonly made from bronze and carbon-based materials due to their important characteristics that ensure durability and effective sealing in various applications. The choice of bronze as a material is due to its excellent corrosion resistance and wear properties, which are vital in environments where mechanical seals operate under pressure and in fluid media.

Carbon-based materials are particularly favored because they possess low friction properties, allowing them to effectively minimize wear during operation. Additionally, carbon materials can provide thermal stability, which is essential for maintaining the sealing function under varying temperature conditions.

The combination of these materials ensures that mechanical seals maintain their integrity and functionality even in demanding conditions, making option B the most appropriate answer regarding material selection for mechanical seal rings.
