Centrifugal Cast Bronze
Physical properties of centrifugal casting bronze such as tensile, creep, & fatigue strength are increased up to 30% over static & investment casting methods.
Centrifugal cast bronze metal purity withstands greater overload & strain without fracture.
Thousands of dies are available to eliminate the expense of buying, storing, maintaining, & insuring patterns.
Blowholes, porosity, & inclusions of centrifugal cast brone are eliminated before finish machining.
Expensive machining time is not wasted on defective parts & material waste is significantly reduced.
The centrifugal casting bronze method provides economical production of a diversified range of sizes, shapes, & quantities.
Centrifugal cast bronze are often called “liquid forgings” because in the centrifugal method, molten metal is literally forged by the high compressive pressure exerted by the centrifugal force.
Key characteristics of centrifugal cast bronze emerge from the “molecular packing” action common only to the high-velocity centrifugal casting method:
Since the parts are formed under pressures plenty of times that of gravity, they exhibit a denser, closer-grained structure with greatly improved physical properties.
centrifugal cast bronze unlike conventional gravity or static castings that chill from both the inside & outside surfaces, centrifugal cast bronze freeze from the outside surface inward. The result is a part free of shrinkage cavities, gas pockets, & blowholes.
In the work of spinning, heavier metal is forced outward, displacing the lighter oxides & impurities & causing them to “float” inward toward the central axis to be removed later in the boring operation.
