The fastest-cutting brasses — the benchmark for high-speed machining. Pick this when cycle time per part is what decides your cost.
Hot-working alloys built for pressure, heat and complex forged shapes. Pick this for valves, fittings and hardware formed hot in dies.
Tin-bearing, corrosion-resistant alloys for marine and wet environments. Pick this for marine hardware and wet, corrosive environments.
Balanced machinability, strength and pressure-tightness for general engineering. Pick this for the broad middle of turned and milled brass work.
Eco-compliant alloys for potable water, food contact and export markets. Pick this when regulations or export markets rule out lead.
Reading the tables
UNS (American) — C-numbers like C36000, used across ASTM specifications.
EN (European) — CW-numbers like CW614N, from the EN 12164/12165 series.
BS (British) — CZ-numbers like CZ121, still common in legacy drawings.
JIS (Japanese) — C-series like C3604, standard across Asian OEMs.
IS (Indian) — IS 319 and related Indian standards.
ISO symbol — the chemistry itself, like CuZn39Pb3: copper, zinc, lead.
