CuZn10 has very good cold forming properties and is well suited for e.g. coinage, beating, embossing. This alloy has a higher strength as pure copper. It has good welding and brazing properties as well as a good corrosion resistant and is not fragile to stress corrosion and dezincification. CuZn10 is principally used in jewelry, metal goods, and watch industry and in electronic industry for installation parts. We produce qualities with grain sizes below 5 mm if needed.

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 Uses :
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.

Red Brass with a nominal composition of 80 % copper and 20 % zinc approaches the mechanical properties of CuZn30 but with corrosion properties only slightly inferior to CuZn15. This alloy has a color between yellow and golden red and finds distinctive uses in decorative trim applications. Its color and tonal qualities prove advantageous for musical instruments. Thermostatic and instrument bellows and flexible hose utilize the combined ductility, strength and corrosion resistance characteristics of this alloy.

Typical Uses :
Architecture: medallions, ornamental components, spandrels Builders Hardware: decorative panels Consumer: clock dials, musical instrument parts, plaques Electrical: battery caps, rotor bars for AC motors Industrial: flexible hose, flexible hose bellows, pump lines, welding wire other tokens.
