World’s Largest Die Inventory

The largest inventory of centrifugal dies in the world includes nearly two thousand horizontal and vertical configurations. Therefore, zero tooling cost is likely for most applications. Dies can also be optimized for larger / long running projects. When using net-shaped centrifugals, intricate detail is added. The process is ideal for complex parts with bosses, pads, flanges, ribs, etc. Considerable machining cost is avoided by casting in the shape. Near-net shaping can be gained through the use of sand inserts placed in the rotating die to add shape to the O.D. of the centrifugally cast part. For more info about how this capability might help, click on net-shaped centrifugals, or call us.

Southern Centrifugal Capabilities

Fully machined centrifugal castings and continuous cast bar, including bronze bar stock cut-to-length, which had been provided by our Southern Centrifugal Division in Chattanooga, TN are produced by Wisconsin Centrifugal. Contact us for your complete-to-print components in nearly any copper-based alloy previously produced by Southern Centrifugal in Chattanooga, TN; that includes gear blanks, pump components, bronze bushings, and a range of bronze centrifugal castings. This is also your only source for high performance Bearium Bronze. Bearium is a material of choice for high friction applications, especially those in environments that are difficult or impossible to service.

Alloy Grades & Modifications

We have nearly 600 alloy compositions including proprietary and patented alloys, as well as advanced development and mechanical patents improving the performance and life of castings. We routinely pour hundreds of ferrous, non-ferrous and special grades like iron, nickel, copper, and cobalt-based, alloys. Wisconsin Centrifugal brings much expertise in modifying chemistries to improve performance in dozens of markets. In addition to industry standard alloys, MetalTek regularly works with customers to modify grades to deliver the performance needed for their particular application and environment.
