Until 1994, Globe Valve dealt solely in red brass 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 foundry learned that gating for the yellow brass permanent mold castings needed to be three times the size of gating for the red brass sand castings.
At a pace of 1 per day, each section required a 400-lb red brass
pour from Wagner's induction furnace.
Peters discussed the development of lead-free selenium-bismuth (Se-Bi) replacement alloys for red brass that will help nonferrous foundries that supply plumbing fixtures comply with NSF Standard 61, which sets safe levels for leachable materials in plumbing systems.
These can be overcome with a debrittling addition of phosphorous, which improves tensile and elongation properties, and imparts more ductility in red brass.
That means no veining, burn-on or penetration in the vanes of impellers of red brass
, high-leaded bronze, cupro-nickel and other non-ferrous alloys.
Since presenting technical papers on pressurized gating for red brass
aloys and effective gating and risering for aluminum bronze production castings, the Gating and Risering Committee has begun research on the effects of phosphorus on the fluidity of red brass
The Effects of Shotblasting on the Ductility of Red Brass
In addition to its foundry, which melts and pours some four million pounds of red brass
a year, the company operates machining, nickel-chrome plating, assembly and warehouse facilities.
The Electric Materials Co offers many other nonferrous alloys, such as red brass
, aluminum bronze, silicon bronze, copper-nickel, copper-tin-zinc and copper-zinc alloys.
