Machining Brass CZ121 (CW614N)

Machinability is rated excellent — one of the friendlier materials on a machine tool — expect efficient cycle times and good surface finish at sensible cost. Brass CZ121 and CZ131 are among the most economical materials to machine — their outstanding chip-breaking behaviour allows high speeds and excellent surface finish. Beryllium copper must be machined with appropriate respiratory controls in place.

Our standard achievable tolerance on Brass CZ121 (CW614N) is ±0.005mm under normal conditions, with tighter tolerances on critical features agreed at quotation. Standard finishes: As machined, nickel plate, chrome plate. Full material traceability with MTR and CoC documentation on every order.

Typical applications

Precision valves, pneumatic fittings, connectors, instrument housings.
