85/15 Red Brass Tubes

Red Brass Pipe / 85/15 Red Brass Tubes

85/15 Red Brass Tubes are copper-rich alloy tubes containing approximately 85% copper and 15% zinc, offering excellent corrosion resistance, strength, and durability. They perform reliably in marine and industrial environments, with good resistance to seawater and dezincification. Common applications include plumbing systems, heat exchangers, condensers, marine hardware, and fluid transportation equipment where long service life and dependable performance are essential.

C23000 brass is the most durable of all metals for commercial water pipe in the practical price range. Excellent for its resistance to dezincification and season cracking for which the high copper brasses are known. Moderate strength and good retention of spring properties. Specified for underground service lines since it offers greatest corrosion resistance to all types of portable waters. Applications for C23000 brass include costume jewelry, fire hose couplings, zippers, and condenser and heat exchanger tubes. Popular as an outdoor metal and has found for itself a very important place in modern architecture. also known as Nordic Brass. The EN equivalent for this alloy is CuZn15.

Typical Applications:

  • Architecture: etching parts, trim, weather strip, Builders Hardware: kick plates, Consumer: badges, coinage, compacts, costume jewelry, dials, fire extinguisher cases, lipstick containers, medallions, nameplates, plaques, rouge boxes, tokens, zippers, Electrical: conduit, rotor bars (AC motors), screw shells, sockets Fasteners: eyelets, fasteners, Industrial: condenser tubes, fire extinguishers, flexible metal hose, heat exchanger shells, heat exchangers, pickling crates, pump cylinder liners, radiator cores, tags, tubing for heat exchangers, tubing for instrumentation, Other fire hose couplings Plumbing fittings, j-bends, pipe, pipe nipples, pipe service lines, pump lines, service lines, traps
