Sintered Porous Bronze Mufflers, Breather Vents, and Filter Discs for Pneumatic Systems

Sintered Bronze Components

CMI Sintered Bronze Components are high-performance porous elements engineered for pneumatic, air filtration, and noise reduction applications. Manufactured from premium spherical bronze powder (typically 90% Copper + 10% Tin), these components feature a uniform porous structure that ensures stable permeability and a low pressure drop.

Widely utilized as pneumatic mufflers, silencers, and breather vents, our sintered bronze parts provide exceptional acoustic damping and particulate protection for valves, compressors, and actuators. These components are inherently spark-suppressing and corrosion-resistant, making them a cost-effective and reliable choice for high-volume industrial and OEM production. CMI offers full customization, including various thread types (NPT, BSP, metric) and complex geometries such as discs, cones, and self-lubricating bushings, providing an ideal alternative to international brand components in demanding industrial environments.
