SPECIFICATION CROSS-REFERENCE CHART

C89844 is a C844 lead-free replacement alloy. C89844 supports the market demand for lead-free material and compliance with the 3874 Reduction of Lead in Drinking Water Act (effective January 2014).

Info

Product Description: Bismuth Tin Bronze
Solids: 1/2" to 10" OD
Tubes: 1 1/8" to 9" OD
Rectangles: Up to 15" wide
Standard Lengths: 144"
Shape/Form: semi-finished, mill stock or near-net shapes, anode, bar stock, billet/bloom, squares, hex, plate, profile or structural shape, flats/rectangular bar
Compliance: C89844 is compliant with key legislation including (1) Federal Safe Drinking Water Act 1974 - SDWA, (2) Federal Reduction of Lead in Drinking Water Act 2011 and (3) California AF1953
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

Typical Uses

Plumbing: fittings/valves for potable water
