Description
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.
Characteristics
- Typically 90% copper and 10% tin
- Particle size -60 mesh (<250 µm)
- Apparent density 2.2 g/cc to 3.0 g/cc
