What Are The Mechanical Seal Materials?

Mechanical seal materials mainly include the following categories:

Metallic materials. Including aluminum, stainless steel, lead, indium, etc. These materials are widely used in mechanical seals under various working conditions due to their excellent corrosion resistance and mechanical strength. 12

Non-metallic materials. Such as graphite, ceramics, silicon carbide, silicone rubber, etc. These materials have high temperature resistance, low temperature resistance, corrosion resistance and other properties, and are suitable for specific sealing needs. 13

Composite materials. Including rubber, polyurethane, fluororubber, etc. These materials combine the elasticity of rubber and the corrosion resistance of other materials, and are suitable for occasions that require both elasticity and corrosion resistance. 14

Carbon materials. Such as carbon fiber and cemented carbide. These materials are used in high temperature, high pressure and highly corrosive environments due to their high hardness, high wear resistance and high temperature resistance. 26

Ceramic materials. Such as alumina, silicon nitride, etc. These materials perform well in acid, alkali and solvent strong corrosive processes, but the cost is high and cannot withstand extreme pressure. 2

Choosing the right mechanical seal material needs to be selected according to the specific working conditions, requirements and needs to ensure the efficiency and life of the mechanical seal and reduce the cost of maintenance and replacement.
