Diffusion Alloyed Bronze


Tin powder is diffused into copper powder on a belt furnace and typically formulated to 90% copper and 10% tin. These diffusion alloyed powders are engineered for low noise sintered bearings.

The sintered pore structure of the bearings provides a uniform controlled porosity and oil permeability for excellent hydrodynamic lubrication at lower shaft loads and higher rotational speeds.
