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 significantly reduced.
• 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 process:

• 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.

Production Capabilities:

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 allowance remaining.
