It has excellent wear resistance and seizure resistance of casting, and it is the oil impregnated bearing that has internal porosity by
repeated composition adjustment and heat treatment in the porosity.

qApplication
· Less noise owing to porous structure.
· High dimensional stability due to uniform material quality.
· Where reduction in oil lubrication is desired.
· Where reduction in vibration and sliding noise is desired.

Order
The major composition is copper alloy. With addition of special elements such as tin, zinc, etc., generation of crystal in solidification of
molten metal is controlled. This easily generates minute shrink holes or discharge holes of melting gas. The base metal of the bearing has
minute porosity and it is impregnated with high grade lubrication oil.
