Application:

This alloy is generally used in producing supports and bearings for hardened or chromium-plated

steel shafts. It can be profitably used in complicated mouldings for hydraulic applications (bodies and

impellers of centrifugal pumps) because of its high castability. It is used for toothed wheels

coupling with no-end steel screws.
