The finished NAVI Titanium sheets can be cut, bent, welded, and stamped, and can be processed into flat sheets, cylindrical components, and customized-shaped filter elements. 

Relying on controllable interconnected microporous structures, high-strength rigid bodies, and excellent adaptability to demanding operating environments, sintered stainless steel sheet has become a core functional substrate for noise reduction and damping components across multiple industries. It effectively overcomes the limitations of traditional organic damping materials, including aging, particle shedding, limited temperature resistance, and the single damping effect of conventional perforated plates. It is widely applied in transportation, industrial equipment, aerospace, energy systems, precision machinery, and other fields, providing long-term and stable optimization solutions for advanced equipment.

 

In the field of damping and noise reduction for new energy vehicle electric drive systems, sintered stainless steel plate serves as a key damping component designed for harsh operating conditions involving high pressure, high temperature, and strong vibration within vehicle compartments. It is mainly installed in electric drive intake and exhaust chambers, high-pressure fluid pipeline interlayers, thermal management ventilation modules, and other critical locations. Traditional flexible damping components are prone to aging failure and insufficient temperature resistance under frequent high-frequency start-stop conditions of electric drive systems, making long-term stable noise reduction difficult. In contrast, the sheet relies on its stable microporous structure to efficiently dissipate broadband airflow noise generated during electric drive operation, effectively suppressing high-speed airflow turbulence and pipeline resonance.

 

For continuous pressure fluctuations and airflow impacts in hybrid and pure electric vehicles, the sheet can evenly regulate flow field pressure, buffer pulsation impacts, and prevent vibration transmission to the vehicle body, significantly reducing low-frequency booming noise and high-frequency mechanical noise inside the cabin. Meanwhile, its rigid integrated structure provides excellent fatigue resistance, no volatile emissions, and no particle shedding, allowing long-term operation in enclosed high-temperature compartments while continuously improving vehicle NVH performance. It serves as a core substrate for advanced noise reduction and damping systems in new energy vehicles.
