C86300 Manganese Bronze Bridge Plate

Atlas Bronze offers C86300 Bridge Plate per ASTM B22 / Manganese Bronze. C86300 Manganese Bronze Bridge Plate is available as Continuous Cast Bar Stock dual certified to both ASTM B505 and ASTM B22. We also offer a select number of sizes in Sand Casting (ASTM B584) as well. *The method in which the material is cast will depend on your size, specification and desired quantity.*

Our C86300 Bridge Plate per ASTM B22 is available in Standard thicknesses or we can cut your desired thickness, width and length from one of our Big Blocks! We regularly stock our C86300 Big Block Plates in a variety of sizes to achieve optimal cutting capacity:

  • 4" thick x 12.2" wide
  • 5" thick x 15" wide
  • 8" thick x 15-7/8" wide
  • 10" thick x 12" wide
The specification ASTM B22 establishes requirements for bronze castings for turntables, movable bridges and bridge parts, and bronze castings suitable for use in bridges and other structures for fixed and expansion bearings in which motion is slow and intermittent. The following Copper Alloys are specified: UNS No. C86300, C90500, C91100, C91300, and C93700.
