CuAg0.1
CW013ASilver-bearing copper — Ag 0.08-0.12% addition to high-conductivity copper. Ag raises the recrystallization/softening temperature by ~100°C without reducing electrical conductivity (>100% IACS). Used for electric motor commutators, soldered heat exchangers, and any Cu application requiring soldering/brazing without softening. Also welding electrodes and lead frames.

CuZn37
2.0321Lead-free alpha/alpha+beta brass (63% Cu, 37% Zn). Compromise between cold formability (CuZn35) and hot formability (CuZn40). The most widely used unleaded brass. Used for cartridge cases, radiator cores, lamp components, plumbing fixtures, and decorative hardware.
CuZn36Pb3
CW603NFree-cutting leaded brass — the benchmark for non-ferrous machinability (rated 100%). Lead particles act as chip breakers for excellent surface finish. Used for screw machine parts, fittings, valves, watch components, precision mechanics, and electrical connectors. Old DIN number 2.0375.
CuSn6
CW452KPhosphor bronze with 6% tin — better cold formability than CuSn8 at slightly lower strength. Excellent spring properties and fatigue resistance. Used for electrical connectors, spring contacts, switch parts, bellows, bourdon tubes, and precision springs.
