In the presentation, "Evaluation of Grain Refinement of Leaded Yellow Brass and EnviroBrass III using Thermal Analysis," (03-119) J.
Sadayappan, CANMET, spoke on "Hard Spot Formation in Grain Refined Yellow Brass and EnviroBrass III" (03052).
Based on results of the electrochemical polarization and salt fog tests, high manganese brass (C99700) is the most corrosion-resistant alloy and high strength yellow brass (C86300) and aluminum bronze (C95400) are the least resistant to corrosion.
Five alloys--pure copper (C80100), aluminum-bronze (C95400), high-zinc yellow brass (C85800), silicon-brass (C87500) and silicon-bronze (C87600)--were evaluated using these two castings.
Globe Valve continued using the red brass sand molds for its "under-the-counter" or "behind-the-wall" work and switched to a low-lead
yellow brass alloy using the permanent mold process for finer surface finish faucets and other cosmetic plumbing castings.
The
yellow brass (C86300) and aluminum-bronze (C95400) are the least resistant to corrosion in all the test environments.
The mechanical, fracture toughness, impact and fatigue properties of 13 lead-free copper alloys (aluminum bronzes,
yellow brass, high-strength
yellow brass, silicon brass, manganese
yellow brasses and the high-copper alloys) were measured.
discussed AFS Research that focused on the effect of an aluminum addition on the microstructure and fluidity of high zinc
yellow brass.
The
yellow brass (C85500, C85800 and B-2) group is the most widely used alloy in the U.
The low-zinc
yellow brass (C85200) also was susceptible to drossing and hot tearing, while the high-zinc
yellow brass (C85800) was prone to drossing but not to hot tearing.
