CENTRIFUGAL CAST BRONZE
Centrifugal castings are frequently referred to as "liquid
forgings" because in the centrifugal process, molten metal is literally forged
by the high compressive pressure exerted by the centrifugal force.
- Physical properties
such as tensile, creep, and fatigue strength are increased up to 30% over static and
investment casting methods.
- Centrifugal cast metal purity withstands greater overload and strain without fracture.
- Thousands of dies are available to eliminate the expense of buying, storing,
maintaining, and insuring patterns.
- Blowholes, porosity, and inclusions are eliminated before finish machining.
- Expensive machining time is not wasted on defective parts and material waste is
- The centrifugal casting process provides economical production of a diversified range of
sizes, shapes, and quantities.
Key characteristics emerge from the
"molecular packing" action common only to the high-velocity centrifugal casting
Since the parts are formed under pressures many times that of gravity,
they exhibit a denser, closer-grained structure with greatly improved physical properties.
During spinning, heavier metal is forced outward, displacing the lighter
oxides and impurities and causing them to "float" inward toward the central axis
to be removed later in the boring operation.
Unlike conventional gravity or static castings that chill from both the
inside and outside surfaces, centrifugal castings freeze from the outside surface
inward. The result is a part free of shrinkage cavities, gas pockets, and blowholes.
Anchor bronze centrifugal castings are available in
most copper alloys. Outer diameters are available up to 124 inches (3,150mm). Our
centrifugal cast bronze tube products are proof machined with the recommended finishing
