P0.05

Mechanical Properties

Tensile:≥250 MPa;Yield:≥200 MPa;Elongation:≥10%

Equivalent Grades

CEN / UNS C18800

Applications

Electrical, decorative, industrial

Available Forms

Sheet,Bar,Tube

Uses

Copper-base alloy with high electrical/thermal conductivity, corrosion resistance and antimicrobial properties. Zinc forms the brass family; higher zinc raises strength and machinability. 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.
