Cu-ETP (CW004A)
2.0060Electrolytic tough pitch copper — 99.90% Cu minimum with 0.02-0.04% oxygen from electrolytic refining. The standard electrical-grade copper worldwide (IACS 101% conductivity). Highest electrical and thermal conductivity of any commercial copper grade. Easy to cold form, hot form, and solder/braze. Cannot be welded in oxidizing atmosphere (embrittlement from oxygen). Used for electrical busbars, wire, cable, transformer windings, circuit boards, heat exchangers, roofing, and plumbing. ASTM: C11000, UNS C11000.

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.
