Products / Federalloy® / C89325

  • Bronze Family: Bismuth Tin Bronze
  • Solids: 1/2"  to 10" OD
  • Tubes: 1 1/8" to 9" OD
  • Rectangles: Up to 15" wide
  • Type: Copper alloy
  • Shape/Form: Bar stock, flats/rectangular bar, hex, squares
  • Benefits: Good machinability, unique Federalloy® technology enables production engineers to tailor any Federalloy® alloy to their own requirements, good polishing and plating characteristics, better castability at lower temperatures which results in lower costs to end users, assures that elongation approximates its leaded alloy counterparts, "no burn-in" feature enables Federalloy® castings to have more definition which results in crisper markings and more legible identification numbers, superior microstructural characteristics, improved finish requires less shot blast which reduces cleaning costs and shortens cycle times
