Brass C210 (gilding metal) is a copper-rich brass (about 95% copper, 5% zinc) with high electrical and thermal conductivity and good ductility, suited to jewelry components, craft metalwork, and decorative hardware.
C210 (gilding metal, CW500L) is a copper-rich brass of about 95% copper and 5% zinc. The low zinc content gives it among the highest conductivity of the brasses and high ductility, while strength is modest: tensile strength rises from about 240 MPa annealed to about 450 MPa cold worked.
Brass C210 is a good option for jewelry components, craft metalwork, and decorative hardware.
