Performance characteristics and applications: Titanium-based cermet high-pressure plungers have ultra-high hardness of 1600HV, excellent wear resistance, and high-temperature oxidation resistance. Their unique self-lubricating property and low friction coefficient significantly improve operating efficiency, while the low-density design achieves lightweight and energy-saving effects. They are widely used in extreme working conditions such as petrochemical industry and high-pressure fluid transportation, completely solving the pain points of traditional steel plungers, such as fast wear, dependence on lubrication, and easy failure at high temperatures, and providing a long-term and stable core power transmission solution for high-pressure equipment.
