Brass is a metal alloy made from copper and zinc. Due to its attractive gold appearance, brass is often used to make decorative products.
This alloy is non-magnetic, easy to cast, and usually doesn’t require surface finishing. It has a low coefficient of friction, low melting point, good malleability, and high corrosion resistance.

Common Brass Alloys
230 Brass / UNS C23000 / EN CW502L
Excellent corrosion resistance against seawater, and ideal for hot and cold working. Has a machinability rating of 30, and can be brazed and enameled. Applications include steam and hydraulic castings, weather stripping, valves, conduit, gears, sockets, and statues.
240 Brass / UNS C24000 / EN CW503L
Excellent ductility and ideal for deep drawing. Better mechanical properties than 230 Brass, but less corrosion resistant. Can be easily hot and cold worked. Applications include battery caps, flexible metal hoses, bellows, musical instruments, clock dials, and pump lines.
260 Brass / UNS C26000 / EN CW505L
Has cold working and deep drawing properties, and allows for severe cold deformations due to high ductility. Applications include radiator cores, tanks, ammunition cases, flashlight shells, electrical components, lamp fixtures, fasteners, locks, hinges, rivets, and plumbing parts.
270 Brass / UNS C27000 / EN CW506L
Stronger than 260 Brass, but slightly harder to the machine. Excellent soldering and brazing properties, and suitable for both hot and cold working. Applications include handrails, kick plates, grommets, and bead chain.
330 Brass / UNS C33000
Excellent cold working properties, good corrosion resistance and machined more easily than 230 Brass and 240 Brass. Commonly used in pump cylinder liners, power cylinder primers, and J-bends.
340 Brass / UNS C34000 / EN CW600N
Excellent machining and soldering properties with high resistance to corrosion. Applications include dials, engravings, instrument plates, clock and lock parts, hose fittings, threaded connectors, and couplings.
Free Cutting Brass
360 Brass / UNS C36000 / EN CW603N
Has the highest possible machinability rating of 100, and is used as the reference for machinability of other metals. Applications include fluid connectors, threaded inserts for molding, and hose barbs.
377 Brass / UNS C37700 / EN CW612N
Has an highest possible hot forgeability rating of 100, good soldering and brazing characteristics, and is easily machined. Applications include furniture hardware, fuse bodies, and golf putters.
