P	0.008

Chinese Standard

ASTM B301

Applications

Electrical, plumbing, heat exchangers, marine, architecture.

Available Forms

Sheet, Plate, Bar, Tube, Rod, Wire, Strip

Uses

Copper-base alloy with high electrical/thermal conductivity, corrosion resistance and antimicrobial properties. Tin forms bronzes with excellent bearing and seawater corrosion resistance. Used for electrical connectors, busbars, heat exchangers, marine hardware, coins and decorative parts.

Heat Treatment

Solution treat (for age-hardening brasses/bronzes) ≈700–900 °C and age; many copper alloys are supplied work-hardened; anneal 300–650 °C.

Precautions

Work-hardens readily; anneal between heavy forming passes. Some leaded grades are less machinable but free-cutting; avoid in potable-water lead restrictions.
